·Gas Options: Supports 100% Argon for aluminum, 100% CO₂ for carbon steel, and mixed shielding gases for carbon steel and stainless steel, flux-cored (gasless) wires for carbon steel.
·Supports foot pedal control for both switch activation and amperage adjustment.
·Designed for DC TIG applications on stainless steel and carbon steel.
Notice: This welder cannot TIG weld aluminum. The foot pedal is sold separately.
POWERFUL HF CUT
·20-50A output cuts up to 5/8" (16mm) at 220V or 1/2" (12mm) at 110V.
·Equipped with high-frequency contact arc starting, it effortlessly slices through rough, painted, and rusty surfaces with minimal slag by using safe compressed air.
·Air Flow Control: Adjustable pre-gas and post-gas times to extend consumable life and improve cut quality.
·Works on stainless steel, alloy steel, carbon steel, copper, and aluminum.
STICK WELDING ENHANCEMENT
Optimized for stable and reliable stick welding performance, this machine includes the following pre-configured, non-adjustable features:
·Hot Start – Improves arc ignition by momentarily increasing current during start-up.
·Arc Force – Enhances arc stability, especially under low-voltage conditions.
·Anti-Stick – Automatically reduces current to prevent electrode sticking.
These features are factory-set and not user-adjustable, ensuring consistent operation without the need for manual tuning.
·Featuring a high-resolution screen, it delivers crystal-clear visibility for real-time monitoring of welding/cutting parameters.
·The intuitive interface enables precise adjustments with instant feedback, ensuring optimal control over voltage, amperage, and speed, which is designed to streamline workflows.

Introduction
The YESWELDER MCT-520 110/220V Dual Voltage Welder & Plasma Cutter Combo is a compact, professional-use machine designed for metal fabrication and repair with 6-in-1 capabilities. It combines Synergic MIG, Manual MIG, Flux-Core, HF TIG, Stick welding, and HF CUT plasma cutting, providing one platform for a wide range of welding and cutting tasks.
For MIG work, the machine supports Synergic MIG mode (automatically matches voltage based on selected wire feed speed) and Manual MIG mode (independent voltage and wire speed control). It also includes spool gun readiness for aluminum welding, with one-button activation and auto-switch to Manual MIG mode. The product supports Fe/SS wire sizes of 0.8mm and 0.9mm, and aluminum wire sizes of 0.9mm and 1.2mm, with gas options including 100% argon for aluminum and suitable shielding gases for other materials.
HF TIG uses high-frequency, non-contact arc initiation for improved weld starts, with optional foot pedal control for switch activation and amperage adjustment (DC TIG applications on stainless steel and carbon steel; this machine cannot TIG weld aluminum). HF CUT provides 20–50A cutting for multiple metals with adjustable pre-gas and post-gas times. A high-precision digital display helps you monitor and adjust parameters in real time.

It was shipped super fast and the packaging was top notch. I love this little plasma cutter already. It's small and light weight unit but powerful, it's a very good looking unit.
Ive got a lincoln electric 180 pro and for smaller stuff around 3/16 thick so far this welds WAY bettwr, lighter, and much easier to use. Ive worked in the steel industry for 6 year and this machine suprised the hell out of me, worth much more than i paid for it. Easily worth 300$+
So far this little thing has been amazing! It works very well and is super easy to carry around and get small jobs done faster. Definitely worth the money if you’re questioning if it works well, and have already recommended it to several others!
Some people would say “for the money, you can’t beat it” this hood looks & performs like those in the hundreds of dollars range. Plus, you get bright light you can mount wherever you want it. Very comfortable. I have a Jackson I was going to buy a replacement auto lens for it. I’m glad I didn’t.
Does amazing. I’ve weld some pipe and cut a motorcycle neck and weld a raked neck on a frame. Does great on 110 and 220. Bought the spool gun and it also runs flawlessly. Haven’t tried the plasma yet but I’m sure it does just fine too A+
