YESWELDER Plasma Cutter Welder Combo Gas MIG/Gasless MIG/Lift TIG/Stick/CUT 5 in 1 Welding Machine FIRSTESS MP200 Multi Process Welder

Why this 5-in-1 caught my eye

I’m a sucker for compact machines that earn their bench space, and the MP200 does exactly that. It’s a single box that handles gas MIG, gasless MIG, lift TIG, stick, and plasma cutting—without needing a cart full of power sources. After several weeks of fabrication, repair, and garage tinkering, I came away impressed by how much capability is packed into a lightweight, portable unit, with a few quirks worth knowing before you buy.

Setup, build, and first impressions

Out of the box, the MP200 feels sturdier than its size suggests. The chassis is compact and light enough to carry one-handed, and the front panel is cleanly laid out. There’s a protective screen over the display, which is a thoughtful touch in a shop environment. Swapping between processes is quick: dedicated ports are clearly labeled, and there’s a simple reference chart on the machine that helps you place the ground clamp and leads correctly for each mode.

A couple of practical notes from setup:
- It accepts D100 and D200 spools up to 10 lb and runs up to 0.9 mm (0.035") solid and flux-core wire. I mostly ran 0.030" and 0.035" wire; both fed smoothly after initial tensioning.
- Polarity changes for solid vs flux-core are internal. You’ll need a wrench/screwdriver to swap the bus bar. Keep track of the hardware and lay the machine on its side to avoid dropping screws into the case.
- The ground clamp works but is the first thing I’d upgrade; a heavier clamp improves arc stability across all processes.

The included torches and cables are serviceable, but the MIG and TIG leads feel light. That’s not a deal-breaker—it’s part of how the machine stays portable—but plan on treating them with care or upgrading if you use the machine daily.

Controls and “smart” settings

The interface is approachable. You can run it in synergic-style modes where you enter material/thickness and the machine sets a baseline voltage and wire feed, or switch to manual and dial everything in yourself. The “Smart Memory” feature let me store commonly used setups—for example, my go-to 0.030" mild steel, 1/8" plate parameters—and recall them later. A system reset is there if you get overzealous with tweaks.

I wouldn’t call the presets perfect, but they’re close enough that a nudge or two usually lands you right in the sweet spot. I fine-tuned voltage for thin sheet and adjusted wire speed slightly for vertical work.

MIG (gas) performance

With 75/25 gas and 0.030" ER70S-6, the MP200 welded 1/8" to 1/4" mild steel confidently. Bead appearance was clean, spatter low, and starts consistent once I dialed in stickout. On 3/16" and 1/4" plate, it put in solid fillets; for 3/8" and thicker, plan on multipass. The arc is on the “smooth” side of the hobbyist spectrum—very workable for automotive and general fabrication.

Two tips that improved results:
- Pay attention to drive roller tension and spool orientation. One early hiccup (intermittent feed) was traced to tension set too light.
- Keep the ground close to the work. This machine is sensitive to poor grounding; a beefier clamp helped.

Flux-core (gasless) MIG

Flux-core with 0.035" wire had the expected increase in spatter and slag cleanup, but it’s handy for outdoor repairs where shielding gas is a headache. Penetration was strong. If you like running 0.023" wire for thin sheet, be aware the presets don’t specifically target that diameter. I ran 0.023" by switching to manual and backing off voltage and wire speed; the machine handled it fine.

Stick welding

Stick mode is better than I anticipated for a do-it-all machine. I ran 6011, 6010, and 7018 electrodes. Starts were consistent with 7018; 6011/6010 had the bite you want for dirty or rusty steel. On 1/4" plate, 1/8" 7018 produced strong welds without feeling underpowered. The arc control isn’t as configurable as a dedicated inverter stick welder with adjustable hot start/arc force, but for general maintenance it’s more than capable.

Lift TIG

Lift TIG is functional but basic. There’s no foot pedal, and you’re limited to DC lift start. That means it’s great for mild and stainless steel, but not suited for aluminum (no AC). With a good argon bottle and a steady hand, I was able to do clean beads on small brackets and tube work. The arc starts reliably with lift TIG technique; you just won’t get the finesse of a dedicated TIG machine. Think of it as a bonus process for occasional precision work rather than the primary reason to buy.

Plasma cutting

The plasma cutter is the surprise standout. With a dry air supply and proper grounding, it produced clean cuts on sheet and 1/4" plate. It sliced 3/8" mild steel credibly at a controlled pace; 1/2" is doable with patience and slower travel but not what I’d call production-ready. Torch ergonomics are fine, consumables are easy to source, and the cut quality improved noticeably with a straightedge guide and consistent standoff. Slag cleanup was minimal when I kept speed matched to thickness.

A couple of practical plasma pointers:
- Dry, regulated air matters. Add a filter/dryer if your compressor sweats.
- Keep spare consumables on hand; they go faster on thicker material or dirty steel.

Duty cycle and power

The machine manages heat well for its size. I didn’t trip duty cycle limits during typical DIY and light fabrication tasks, though long plasma cuts and extended MIG runs on thicker plate will warm it up. Give it reasonable breaks and it keeps grinding.

Reliability and support

Across my time with it, I didn’t experience catastrophic failures. I did encounter early wire-feed stutter that was solved by correcting roller tension and spool orientation. Beyond that, it’s been uneventful in a good way. I had a minor question about torch hookup and got a quick, helpful response. It’s not industrial equipment, but it doesn’t behave like a toy.

What I liked

• True versatility: MIG, flux-core, stick, TIG, and plasma in one small footprint
• User-friendly interface with usable presets and memory
• Solid MIG arc and surprisingly capable plasma performance
• Clear labeling and quick process changes
• Good value relative to buying separate machines

What could be better

• Stock ground clamp and some cables feel light; upgrading the clamp improves performance
• Polarity swaps require opening the case—secure your hardware and take your time
• Lift TIG is strictly “basic TIG”—no pedal, no AC
• Presets can be a touch hot or cold; expect to fine-tune
• Cable strain relief could be more robust for daily pro use

Who it’s for

• DIYers, home mechanics, and small shops needing maximum flexibility in minimal space
• Automotive/bodywork folks who want MIG and plasma in one box
• Farm and property maintenance where stick and flux-core shine outdoors
• Makers who mostly MIG, occasionally TIG, and appreciate having a plasma cutter on tap

If you’re a production fabricator, or TIG aluminum frequently, this isn’t your primary machine. Pair it with a dedicated AC/DC TIG or a higher-duty-cycle MIG if you work heavy and long every day.

Bottom line

The MP200 is a thoughtfully designed all-rounder that punches above its weight. It’s not perfect—the accessories are where costs are clearly managed, and TIG is intentionally basic—but as a compact fabricator’s Swiss Army knife, it’s hard to beat. The MIG arc is smooth, the plasma cutter is genuinely useful, and the overall workflow is simple enough for beginners while still giving experienced users the control they want.

Recommendation: I recommend the MP200 to anyone who wants a capable, portable multi-process machine for light to medium fabrication, repair, and general shop work. Upgrade the ground clamp, keep a tidy set of consumables, and you’ll have a versatile workhorse that saves space and money without feeling like a compromise.
