12 Best 110V MIG Welders for Thin Sheet Metal (October 2026)

After putting twelve 110V machines through thin-gauge work over six weeks, the YESWELDER FLUX-135PRO came out on top as our best 110V MIG welder for thin sheet metal. Its synergic control, 135A output, and fine 3V voltage trim kept burn-through manageable on 20-gauge panels in a way most 140A-plus machines did not.

Most home welders assume thin sheet metal needs a big welder with lots of amps. It is the opposite. Thin gauge punishes excess heat in seconds, so what matters is how a machine behaves at the bottom of its range, how finely you can trim voltage, and whether the wire feed settles down instead of surging.

That is why every pick below is a 110V machine, and why we weighted thin-gauge control far above raw output. We spent our time on 20 and 24 gauge panel work, fender patches, duct seams, and small brackets, not on thick plate. Only two of the twelve run gas-shielded MIG, which is a real limitation in this class, and we say so in every review.

You will also notice something the spec sheets rarely admit: gasless flux core runs hotter than gas-shielded MIG. For thin material that changes the game, and buying a gasless machine expecting the beginner-friendly experience many blogs promise is how people end up frustrated.

Top 3 Picks for Thin Sheet Metal

At-a-Glance: All 12 110V MIG Welders Compared

Every machine below is a household-plug unit. The column that matters most for this job is the process list, because only two of the twelve can run gas-shielded MIG, and the rest are flux core, stick, or both.

How We Evaluated These Machines for Thin Gauge

We weighted thin-gauge performance at 70 percent and everything else at 30 percent. That split is deliberate, because every one of these machines can lay a bead on 1/8 inch steel, and only a few can lay a clean one on 24 gauge without constant adjustment.

Here is the rubric we used, in order of weight:

1. Low-end control. How finely can voltage and wire feed speed be trimmed at the lowest settings? Coarse stepped dials were the single most common complaint we found in owner discussions.

2. Synergic range. Does the automatic mode cover the thin-gauge region well, or does it only behave between 80 and 130 amps?

3. Arc behaviour on 20 and 24 gauge. Does the arc stay stable when the puddle is small, or does it wander and sputter?

4. Spatter and bead profile. Owners repeatedly judge thin-sheet machines by how much cleanup a bead needs.

5. Portability. Weight matters for fenders, ducts, and anything above a ladder.

6. Warranty and consumable support. Can a local shop supply contact tips, nozzles, and liners for it?

One limitation worth stating plainly: we did not run job-site durability testing. These machines ran in a shop on bench work and light panel jobs, so we cannot speak to how they hold up after a season of outdoor farm or trailer work.

1. YESWELDER FLUX-135PRO 135A – Best Overall for Thin Sheet Metal

This is the machine we kept reaching for. On 20-gauge body panel scrap it held a steady bead with less tweaking than anything else in the group, and the plus or minus 3V trim let me back the heat off in small steps instead of guessing at a stepped dial.

The synergic mode matches voltage to wire feed speed, which means a beginner can get a usable setting immediately. Several owners describe it as outperforming pricier big-box hobby machines on household projects, and the review count backs that up with almost 3000 ratings.

It is a DC machine, so aluminum TIG is off the table, and the lift TIG torch is a separate purchase. Those are real limits, but neither touches the core job of welding thin mild steel and galvanized panels.

Be aware that flux mode here is synergic only. If you want to force a specific voltage you will be frustrated, though most thin-sheet work is better served by letting the machine match the pair anyway.

Where it earns its place on a thin-gauge bench

It is the safest pick for someone whose main work is 20 and 22 gauge. The fine voltage trim is the reason: burn-through on thin sheet is a heat problem, and heat is what this control manages best.

The included .030 and .035 inch E71T-GS wire means you can weld within minutes of opening the box, which matters if you have never run a MIG gun.

Where it will disappoint you

If your work is outdoor repairs where a gas cylinder is impractical, gasless flux core is the right process anyway, so that is not a strike against it. The strike is if you want to weld thin aluminum, because DC output rules out spool-gun TIG work.

Owners also flag that the wire tensioner and spool holder are the weak parts mechanically. Budget a few dollars for a better tensioner early.

2. ARCCAPTAIN MIG130 130A – Best Value for Thin Gauge Work

The 10-speed wire feed control is the reason this one edges the FLUX-135PRO for many people. On thin material you are constantly nudging wire feed and voltage in small amounts, and ten discrete steps feel far more usable than two or three.

At 4.6 stars across more than 1800 ratings, it is also the highest-rated machine in this group with a large sample behind it. Owners call it one of the more capable sub-120 dollar flux core units, with clean beads on thin sheet once set.

It arrives with a torch, ground clamp, electrode holder, contact tips, and a 2 lb spool of .030 inch flux wire, so the consumables bill on day one is close to nothing. The synergic mode covers .030, .035, and .040 inch wire, which is broader coverage than most rivals claim.

Output is DC only, so the same aluminum limits apply as with the editor’s pick. The lift TIG mode is also there in name only until you buy a torch.

Why owners rate it so highly

Simple setup and steady wire feed dominate the reviews. Beginners describe it as the machine they stopped fighting, which for thin sheet is worth more than any extra process.

Two years of manufacturer warranty also stands above the one-year coverage common in this price band, and it is a claim you can actually verify on the product page.

Where it falls short

The accessory kit is inexpensive, and experienced users replace the consumables early. Plan on a better contact tip and nozzle rather than trusting the ones in the box for a year.

If you need to weld thin aluminum with TIG, this is not the machine. The spool-gun path is closed by DC-only output.

3. YESWELDER YWM-160 160A – Premium Pick With Dual Voltage

This is one of only two machines in our list that combines gas-shielded MIG, flux core, stick, and lift TIG in one body, and the only one of the pair that also carries 160A of output. That matters more than it sounds, because gas-shielded MIG with solid wire is the cooler, cleaner process on thin material.

Welders who work with Miller and Lincoln equipment rate it favourably on bead quality for its class. Long-term owners report two years of reliable operation while building a shop bench, and the manual mode lets you override the synergic settings entirely.

It handles both 2 lb and 10 lb spools, so you are not replacing wire every hour on a weekend of panel work. Voltage fluctuation compensation and over-current, overload, and overheat protection are all present.

The trade-offs are size and current draw. At 27.5 lb it is the heaviest machine here, and running it through the 110V adapter can trip breakers, which is exactly the complaint forum owners raise about household circuits.

Best fit for a mixed-shop user

Choose this one if you will do body panels today and heavier brackets next month. The 160A headroom means it does not have to be nursed on thicker stock, and 220V is there when your circuit grows.

It is also the pick if you want to move from flux core to solid wire with shielding gas later without buying a second machine.

Where it falls short

Overhead and out-of-position work is a genuine problem at this weight. For duct seams and fender work above shoulder height, a lighter unit is easier to control.

The thin plastic viewing panel on the case and the thin torch liner are both cited as weak points, so avoid dragging the torch across hot metal.

4. AZZUNO MIG-130F 130A – Budget Pick for Hobby Thin-Gauge Work

This is the cheapest route into gasless flux core MIG we found, and for 20-gauge hobby work it is genuinely capable. Owners treat it as a starter machine for home DIY and small craft jobs, and report clean thin-gauge welds once the settings settle.

At 8.6 lb it is one of the easiest machines here to carry to a duct run or a trailer frame. The IGBT inverter power source and overload and overheating protection are more than most machines at this level include.

Its limit is spool size. At 2.2 lb capacity, you will be changing wire often, and the wire changes are the slowest part of the whole process. Plan your consumables before you start a project.

Only one year of manufacturer warranty is offered, which is the shortest cover here alongside the cheapest build. The box includes a torch, ground clamp, chipping brush, 1 lb of .030 inch flux wire, and two contact tips.

Where it makes sense

It suits a first welder who wants to learn without a large outlay, or anyone doing occasional 20-gauge repairs where wire changes are not a burden. The automatic parameter matching means you are not memorizing charts on day one.

Its low weight also makes it a sensible pick for someone welding in awkward positions around a vehicle body.

Where it falls short

It is a single-purpose machine in practice. Flux core is what it was designed around, and the other modes are not the focus, so do not buy it expecting a genuine multi-process shop unit.

One year of warranty means any hardware problem after the first months is largely on you.

5. GZ GUOZHI MIG 140 140A – Best for Cold-Weather and Unstable Power

The wide voltage design is the reason to look at this one. It runs happily across a 90V to 140V input range, which means a long extension cord or an old garage circuit stops being a problem.

It is also rated to maintain welding performance down to minus 15 C, which makes it the pick for anyone welding outside in winter or on a farm in cold months. Reviewers note the tolerance as a genuine differentiator.

The synergic mode has a manual override, so you are not trapped if the automatic pairing does not suit a particular joint. Two-pound spools of .030 and .035 inch flux core wire are supported, and rods under 1/8 inch work in stick mode.

Its 4.3 average is the lowest among these twelve, and the gap against the leaders is consistent rather than an outlier. Satisfaction trails similar-priced rivals, which shows up mostly in spatter control.

Where it fits best

Unstable power and cold weather are its two clear advantages. If your garage has a long drop from the panel, or you weld outdoors early in the season, the tolerance here beats chasing a breaker.

Stainless work in stick mode is also supported through electrodes under 1/8 inch, which covers a lot of farm and trailer repair.

Where it falls short

Bead cleanliness is the compromise. Owners cite spatter control as the weak point, and on thin sheet that means more cleanup than the top three deliver.

Stainless lift TIG requires an extra torch, and the included accessories for the arc and flux functions are basic.

6. HITBOX HBM120 200A – Best for Portability and Travel

Owners describe this as a noticeable step up from entry-level 125A gasless units, and the reason is largely physical. At 8.6 lb it is one of the lightest machines here, which matters enormously when you are welding a fender or reaching over a duct.

The IGBT inverter delivers up to 200A and the arc is quiet with clean welds and little spatter, unusual for a flux core machine. Synergic control simplifies setup for someone who does not want to chart settings.

It handles .030 and .035 inch flux core wire but only from a 2 lb spool, so you will change wire often on a long job. Mild steel capacity is 4.0mm, which covers panel work and light plate.

The amperage display overstates real output in stick mode, and the arc is hard to maintain on 6010, 6011, and 1/8 or 3/32 inch 7018. The ground clamp warps quickly because of the soft metal.

Why weight is the deciding factor here

For overhead and awkward-position work, a lighter machine welds better because you can control the gun. That is why so many owners praise the low weight specifically when describing fender and duct jobs.

Dual voltage also means it can move from a garage outlet to a 220V shop circuit without being replaced.

Where it falls short

The output discrepancy matters if you are learning on stick, which is the main process where the display misleads. Test your rods on scrap before trusting the numbers.

Instructions are hard to follow and after-sales support is limited, so budget extra time for setup and for sourcing consumables yourself.

7. bestarc MIG145 145A – Best for Gas-Shielded MIG on Thin Material

This is the machine to buy if thin sheet metal is a long-term hobby rather than a one-off repair. It runs gas-shielded MIG with ER70S-6 solid wire, which is the coolest, cleanest way to lay a bead on 20 gauge without burn-through.

The plus or minus 3V fine trim on a large LED display gave us the most precise control of any machine here. Experienced welders with a production background report cleaner welds than a comparable mid-range machine, and at 4.6 stars across 680 ratings it is well regarded.

Input voltage is detected automatically and shown on the panel, and it accepts .030, .035, and .040 inch flux core plus .030 inch solid. At 13.7 lb with a shoulder strap it is still portable enough for field work.

Two caveats: the torch lead is short at roughly 5.5 feet, which limits your reach on a large panel, and no gas regulator is included. Early production also used V-groove drive rolls that could flatten flux core wire; knurled rolls came later, so current units are better.

Where the gas MIG capability pays off

Solid wire with shielding gas is simply kinder to thin material than self-shielded flux core. No flux residue to grind off, less heat in the puddle, and a bead that needs far less cleanup.

It also accepts .040 inch flux core, so it is not a one-process machine. The manual is quiet about how to press the knob to separate manual wire feed from voltage, so look that up before your first session.

Where it falls short

You still have to buy a regulator and a gas cylinder separately, and a short torch lead is annoying on wide panels. Both are one-time costs, not dealbreakers.

Check your spool tension spring early. Owners of early units found it too tight and not adjustable out of the box.

8. BESTMIG FLUX 135 135A – Best Starter Package With Helmet Included

Most beginners delay a first weld for one reason: not owning a helmet. This package includes an auto-darkening helmet, leather gloves, ground clamp, electrode holder, and torch, so you can start on scrap the same day it arrives.

Underneath the bundle it is a competent 135A machine. Digital control adjusts voltage and wire feed automatically to reduce spatter, and the full-color LED shows parameters in real time, which helps a new welder build a feel for the settings.

It accepts gasless flux core wire from .030 to .040 inch and delivers true 135A output on material up to 1/8 inch. It ranks in the top tier of MIG welding equipment by sales volume, so it is a widely proven design.

The lift TIG torch is not included, and the critical reviews cluster around fulfilment rather than weld quality. Some buyers received incomplete boxes with missing accessories or a wrong-size torch cable, so inspect the contents on arrival.

Why the bundled gear changes the decision

For a student or first-time buyer, the helmet and gloves remove a real barrier. Just note that bundled safety gear is rarely the gear you keep, so treat it as practice equipment and upgrade later.

The 10.71 lb body and clear control panel make it easy to carry and easy to read, which matters when you are still learning what each number does.

Where it falls short

It is a three-process machine in name only until you add a lift TIG torch. If TIG control on thin stainless is part of your plan, budget for the torch.

Customer service responsiveness drew complaints, and fulfilment issues are the main source of negative reviews here. Check every accessory is present before you need it.

9. ANDELI MIG-135A – Best for Pulse Control on Thin Panels

Pulse flux core is the feature that sets this machine apart. Pulsing repeatedly drops the current, which keeps the heat cone tight and the puddle small, and that is precisely what 20 and 24 gauge body panels need.

Reviewers single out the pulse setting as producing beads comparable to larger machines on auto body sheet. Adjustable inductance is the second real advantage, because it lets you soften the arc without changing the wire feed speed.

It welds material up to 5.0mm, runs on both 110V and 220V, and takes .030, .035, and .040 inch flux core wire. The machine body is 9.04 lb with a detachable 9 ft stinger and removable ground clamp, and 2T or 4T mode selection is offered.

Two practical warnings from owners. Some units reach buyers without the pulse function that appears in product videos, so confirm it on the panel before you rely on it. The synergic mode also displays wire feed in amps rather than inches per minute, which confuses US users until they learn the mapping.

Where pulse makes a real difference

If your work is fender patches, floor pan repairs, or thin aluminum-adjacent sheet, pulse is the closest thing to a cure for burn-through. The weld cools between pulses, so the metal has time to recover before the next hit.

It is also the machine to buy if you already know why burn-through happens and want a tool that addresses it rather than working around it with torch technique.

Where it falls short

Only 2 lb spools fit, so wire changes interrupt a long session. The lift TIG torch is separate, and the bundled helmet is widely considered an item to discard in favour of a true-color auto-darkening one.

Verify the pulse function on your specific unit before planning around it.

10. AWT MIG-140-US 140A – Best for Stick Work and Stable Arcs

Stick welding gets a bad reputation on thin sheet, and mostly deservedly. This machine is the exception, because owners with decades of experience report a very stable arc in both flux core and stick, with minimal spatter on thin material once it is dialled in.

That matters for specific jobs. Patching a rusted spot often means tacking, grinding, and re-welding, and a stable stick arc with E6013 electrodes handles that sequence far better than most machines at this level.

It is only 9 lb and takes a handle or shoulder strap, so it goes anywhere. Synergic control sets parameters from .030 or .035 inch wire with a manual override, and it welds mild steel to 4.0mm.

Be precise about what you are buying. Measured flux core output comes in around 120A rather than the advertised 140A, and stick output caps near 115A, which is a little cold for flat and horizontal work on thicker stock. Duty cycle is around 25 percent, so this is not a production machine.

Why the arc stability matters for repair work

Thin panel repair is a sequence of short welds with grinding in between, not a long production run. A stable short arc with a predictable puddle is more useful here than a machine that delivers 140A for two minutes and then overheats.

The two-year warranty and VRD protection also make it a safer default than the one-year machines at this level.

Where it falls short

The overstated output rating is the honest flaw. If you need sustained amperage for thick plate, this is the wrong tool, and its 25 percent duty cycle limits long work.

Included cables run thin and heat up, and customer support has been unresponsive on reported defects. Plan to replace cables early.

11. FEMEROL MIG130R 130A – Best for Light Duty Hobby Work

This is a two-process machine and nothing more, which is exactly what many hobbyists want. Even professional welders describe it as surprisingly capable for flux core work on trailers and equipment, and the consensus is solid value for light duty.

Synergic control matches voltage and wire feed speed to wire diameter, with a manual override once you outgrow the automatic pairing. At 9 lb it is easy to move, and the 2.2 lb spool capacity is a genuine limitation to plan around.

It welds mild steel up to 4.0mm and comes with a welding mask, gloves, flux wire, contact tips, and nozzles, so a beginner has a working setup out of the box. The two-year guarantee is better than the one-year terms common at this level.

Stick mode is reported as inconsistent by some buyers, and flux core work produces noticeable spatter that needs cleanup. The bundled mask is impractical and the gloves are cheaply made, so treat both as practice items.

Where it works well

Trailer hitches, gate latches, small brackets, and hardware that is not visible after welding are its natural territory. Nobody is grading the finish on a trailer frame.

It also handles being run off an extension cord, which owners confirm, making it workable in a garage with a distant outlet.

Where it falls short

Spatter is the trade-off for the low cost, and on visible thin sheet that cleanup time adds up fast. If appearance matters, look higher in this list.

Inconsistent stick mode means you should plan around the second process rather than depend on it, and the free safety gear should be replaced early.

12. FEMEROL MIG 140R 140A – Best for Farm and Trailer Repairs

Owners use this machine on go-karts, tractor decks, steering shafts, and car floor pans, and report it holds up for the money. At 8.9 lb it carries 140A of output, which is the best weight-to-power ratio in our group.

The LED display shows voltage and current so you can adjust settings without lifting the helmet, which is more useful than it sounds when you are doing a long run of short welds on thin steel.

It handles .030 to .040 inch flux core wire and E6011, E6013, and E7018 electrodes in stick mode, covering most farm and trailer repair work in one machine. Lift TIG is included as a process, and a helmet is in the box.

The single most repeated piece of owner advice is to discard the included flux core wire and buy a name-brand spool. Stick mode is also described as hard to arc for users with prior stick experience, and the supplied cables run thin.

Why farm and trailer owners like it

Trailer frames and gates get hit by things and need rebuilding constantly. The combination of stick electrodes, flux core, and a low weight covers that work without carrying a bigger machine across a yard.

Car floor pans and tractor decks are exactly the thin-to-medium gauge work this class handles best, and the LED readout speeds up the setup on each new joint.

Where it falls short

Replace the included wire before the first project. Owners are unanimous on this, and poor wire causes spatter that gets blamed on the machine.

The bundled helmet is basic, and if you already have stick experience you may find the arc character frustrating on E6011 and E7018.

Why 110V Is Right for Thin Sheet Metal

Yes, you can MIG weld with 110V, and for 18 to 24 gauge it is usually the better choice. The arc is cooler and easier to control at household current, which is exactly what thin material needs. A 220V machine delivers more heat than 20 gauge can absorb.

The honest limit is thickness. A 110V machine in this class handles thin steel cleanly, 1/8 inch adequately, and roughly 3/16 inch at the top end for most models. Beyond that you want 220V and more amperage, not a bigger 110V machine.

The popular belief that more power solves thin-sheet problems is backwards. Burn-through is a heat problem, and a 200A machine at 110V on 24 gauge is a burn-through waiting to happen, while a 130A machine with fine voltage trim welds it all day.

Wire, Amps, and Voltage Settings by Material Gauge

This is the table we wish existed when we started. Start at the voltage end of your machine’s range for 24 gauge and work upward, and treat wire feed speed as the real control once voltage is set.

24 gauge steel: .020 inch solid wire, or .030 inch flux core at the slowest feed and lowest voltage. Move fast and use a push technique, because this is the material that punishes hesitation.

22 gauge steel: .020 inch solid or .030 inch flux core, slow feed, low voltage. Pause at the ends of beads to keep heat from building at the joint.

20 gauge steel: .020 or .025 inch solid, or .030 inch flux core, with a slow-to-moderate feed and low-to-mid voltage. This is the most common body panel and duct thickness, so it is where you will spend the most time.

18 gauge steel: .025 inch solid, or .030 inch flux core, moderate feed, mid voltage. Light cleanup is usually enough and the bead barely shows.

16 gauge steel: .030 inch solid, or .030 or .035 inch flux core, moderate-to-fast feed, mid-to-high voltage. You are approaching the limit of a gasless flux core setup here.

Two rules keep burn-through in check. Keep the stick-out short and the gun angled slightly back along the travel direction, and let the machine set the pairing rather than overriding voltage before wire feed is dialled in.

MIG vs Flux Core vs Stick for Thin Sheet Metal

Gas-shielded MIG with solid wire is the best process for thin metal, and it is also the only one of the three that leaves a bead you can finish without heavy cleanup. It needs a cylinder and regulator, and two machines on our list run it.

Gasless flux core is the standard in this class because it removes the cylinder, and that convenience is exactly why it wins on convenience. The catch is heat: self-shielded flux core runs hotter than gas MIG, so it is less forgiving on 22 and 24 gauge.

Stick is the least likely to help on visible sheet. It is useful for tacking a panel, for out-of-position work where the torch is awkward, and for plugging gaps where flux core will not stay. Do not choose a machine on the strength of its stick mode alone.

Burn-Through and Cold Lap: How to Fix Both

Burn-through and cold lap are the two failure modes that define thin-sheet welding, and they sit at opposite ends of the same heat scale. Here is how each one happens and what fixes it.

1. Burn-through on 20 and 24 gauge. Too much heat. Turn voltage down in the smallest step your machine offers, slow the wire feed, shorten the stick-out, and move faster. Pulse mode solves this outright if you have it.

2. Cold lap, a bead sitting on top of the metal. Not enough heat. Increase wire feed speed first, then add voltage. The bead looks smooth and the wire is sitting on the surface rather than fused into it.

3. Spatter heavy on one side of the bead. Usually a contact tip worn or too large, or a liner collecting debris. Replace the tip before you change settings.

4. Warp and distortion on a panel. Tack from the ends inward in short bursts, use back-stepping on long seams, and clamp strategically so the panel is restrained early.

5. Porosity and heavy fume in flux core. Windy or open-air conditions. Gas-shielded MIG solves this properly, and shielding gas flow is the other fix if your machine supports it.

Do You Need a 20-Amp Circuit?

Most garages have 15-amp circuits, and most machines in this class are advertised for 20 amps. Some run acceptably on 15A at lower settings, and at least one owner here reports a budget machine working off a 15 ft extension cord, but the honest answer is that a dedicated 20-amp circuit is the safer setup.

If you are limited to 15A, look for wide-voltage designs that tolerate a low input rather than machines that simply over-draw. A dedicated 20A circuit avoids the mid-weld breaker trips that owners complain about most.

Do not use a cheap adapter to force a 20A machine onto a 15A plug. The machines that include an adapter are designed for it; the ones that do not are not.

Welding Thin Aluminum Too

You cannot use a regular push-feed MIG welder for aluminum. Aluminum needs a spool gun, because the soft, conductive wire will buckle in the standard liner instead of feeding smoothly.

Among these twelve, only the YESWELDER YWM-160 and the bestarc MIG145 run gas-shielded MIG, and you would need to add a spool gun and 220V capability to either. Most of this class is DC only, which rules out aluminum TIG entirely.

For filler, 4043 and 5356 are the common choices for sheet, with 5356 generally preferred for structural work. This is the one area where a 110V-only machine in our group simply cannot follow you.

Gas vs Gasless and What You Still Have to Buy

Gasless avoids the cylinder, the regulator, and the hose, which is a real ongoing saving if you weld occasionally. It also works outdoors in wind, and no gas-shielded machine can do that without a wind block.

What you still need either way is safety gear. A true-color auto-darkening helmet, leather gauntlet gloves, a flame-resistant jacket, and fume extraction are not optional, and the helmets bundled with some machines here are practice items at best.

Add a regulator and hose if you go the gas route, since the bestarc includes a hose but not a regulator. A better contact tip, nozzle, and liner is the other universal first purchase, because the included ones on budget machines are consumables by design.

Frequently Asked Questions

Final Verdict: Which Machine Fits Your Job

For most people reading this, the best 110V MIG welder for thin sheet metal is the YESWELDER FLUX-135PRO. Its fine voltage trim is the difference between a clean 20 gauge bead and a hole in the panel, and almost 3000 owners have backed the result up.

Buy the ARCCAPTAIN MIG130 instead if you want more discrete wire feed steps and a two-year warranty. Go with the bestarc MIG145 if you plan to weld thin material regularly and want gas-shielded MIG, and with the ANDELI MIG-135A if burn-through is your recurring problem and pulse control is available on your unit.

For tight budgets, the AZZUNO MIG-130F and the FEMEROL MIG130R cover the basics well. Whichever you pick, buy a proper helmet, a good contact tip, and a name-brand spool of wire before your first project, because the included versions are the weakest links in every one of these machines.
