YESWELDER MCT-520 Review

Finding a welder that does everything — and doesn’t cost a fortune — usually means making compromises. The YESWELDER MCT-520 promises to fix that with a true 6-in-1 design: MIG, Flux Core, TIG, Stick, Spool Gun, and even a Plasma Cutter built into one box.

It’s aimed squarely at serious DIYers and small-shop fabricators who want flexibility without filling their garage with separate machines. After testing and diving into owner feedback, here’s how it holds up.

First Impressions

Out of the box, the MCT-520 feels surprisingly well built for a sub-$800 welder. The metal casing is solid, the controls are clearly labeled, and the digital display makes setup less intimidating than most multi-process welders.

The interface lets you toggle between welding modes quickly, and synergic MIG settings automatically adjust voltage and wire feed speed based on material thickness — perfect for beginners who just want to get started.

It’s dual-voltage too, meaning you can plug it into standard 110V household power or 220V for heavier work.

Welding Performance

MIG & Flux Core

For most hobbyists, the MIG and Flux Core modes are the real draw — and the MCT-520 handles them well. The wire feed is smooth, arc stability is good, and the smart synergy makes it hard to screw up settings. You can also switch to manual mode if you prefer full control.

Some users note that the wire feed speed can be touchy or inconsistent on early batches, but YESWELDER’s support has been quick to replace units with issues. Once dialed in, it welds mild steel, stainless, and even aluminum (with a spool gun) cleanly.

Stick Welding

Stick mode performs just as solidly. It burns 7018 and 6013 rods without fuss and offers enough power to weld thicker plate steel up to around 3/8”. For general repair and farm work, it’s more than capable.

TIG Mode

TIG welding is where the MCT-520 surprises people. The HF start (high-frequency ignition) makes arc starts clean and effortless, avoiding the scratch starts that cheaper combo welders struggle with. You’ll need an argon tank and TIG torch setup, but for light fabrication or detail work, it does a solid job.

---

Plasma Cutting Performance

The built-in plasma cutter is rated for up to 50A output, and while its marketing claims are a bit optimistic, it performs great within reason. On 220V, it clean-cuts up to about 3/8" mild steel easily, and 1/2" with a slower pass.

It uses standard compressed air, meaning no special gas is required. The cut quality is cleaner than expected at this price, though the standoff torch guide can feel a little loose until you get used to it.

---

Ease of Use & Features

YESWELDER made setup beginner-friendly. Each mode has clear icons and adjustable settings, and the gas check feature helps confirm gas flow before welding.

The digital readout is bright and accurate, and switching between welding and cutting functions is as simple as turning a knob. There’s also built-in protection for over-current, voltage spikes, and overheating, which adds confidence for newer welders.

One small gripe — the ground clamp is undersized. Upgrading to a heavier clamp makes a noticeable difference in connection quality.

---

Customer Support & Durability

YESWELDER’s support consistently earns praise. Several owners mentioned quick, hassle-free warranty replacements and helpful troubleshooting via email.

Durability-wise, the machine feels reliable, though a few users have experienced MIG issues over time. The Stick, TIG, and Plasma modes, however, have proven very consistent long-term. For what it costs, the performance-to-value ratio is hard to beat.

---

Real-World Use

From car restoration to small metal art projects, the MCT-520 has been used for just about everything. One owner even cut out and repaired a truck frame using only this welder.

It’s compact enough to move around the shop, and with a quick polarity change and some flux wire, it doubles as a portable field welder.

---

Value & Verdict

At under $800, this machine offers capabilities usually found in multi-unit setups costing double that. It’s not flawless — the MIG system could be more robust and the plasma ratings a little exaggerated — but the flexibility, ease of use, and strong support make it an incredible deal for DIY welders.

If you’re setting up your first real shop or need a do-everything unit that can handle most jobs, the YESWELDER MCT-520 earns a solid recommendation.

✅ Verdict: 4.1 / 5

A versatile, high-value all-in-one welder and plasma cutter. Excellent for home projects, auto repair, and fabrication — just be ready for a few quirks on the MIG side.
