How to Use
Setup
Based on manufacturer instructions, setup involves connecting the desired torch, selecting the correct voltage (110V or 220V) via the internal switch, and loading wire for MIG/flux‑core or installing electrodes for stick. The intelligent parameter matching system reduces guesswork: after setting voltage, the machine automatically suggests wire speed. YESWELDER provides step‑by‑step video tutorials that reportedly allow beginners to start welding within five minutes.
Operation
Select mode using the mode selector. Adjust amperage and voltage with the physical dials. For TIG, a foot pedal (sold separately) can be connected for hands‑free amperage control. For plasma cutting, set the cut current and follow standard cutting technique. The glove‑friendly controls are designed for heavy‑weld‑glove use.
Maintenance
Typical upkeep includes cleaning and replacing consumables (contact tips, nozzles, electrodes), checking gas connections for leaks, and ensuring ventilation openings are clear. The unit’s automatic protections help prevent damage from overloads, but regular inspection is recommended.
Troubleshooting
Common issues: poor arc start (check ground clamp, voltage setting, or wire speed), erratic plasma cut (clean torch, verify air pressure, replace worn electrode). YESWELDER offers 24/7 technical support via phone/chat and promises a response within 24 hours. The 2‑year warranty covers defects.
Performance & User Experience
The YESWELDER MCT‑520 has earned a 4.3‑star rating from 62 customer reviews (as of its release date). Many users highlight its versatility: the ability to switch from MIG to plasma cutting without changing machines is a significant time‑saver for small shops. The plasma cutter’s 50A output is noted as adequate for sheet metal and thin plate up to 5/16″ clean cut, while the welder handles up to 200A for heavier steel sections.
The large LED display and physical controls receive positive feedback for ease of use, even with gloves. However, a few users mention that the dual‑voltage switching requires opening the side panel, which can be inconvenient. Also, the spool gun (for aluminum) is sold separately, and some users wish it were included.
Overall performance appears solid for its price range, though professional users should note that it’s not a heavy‑duty industrial machine. It is best suited for light fabrication, automotive repair, farm equipment maintenance, and home projects.

Who Should Buy This Product?
Ideal for:
- Home DIYers and hobbyists who want to tackle various metal joining and cutting tasks without buying multiple machines.
- Farm and ranch owners performing repairs on equipment, trailers, or fencing.
- Small repair shops needing a compact, versatile unit for light to medium fabrication.
- Beginners learning MIG, TIG, and stick welding – the smart parameter matching and video support reduce the learning curve.
Not ideal for:
- Industrial or production environments requiring high duty cycles or continuous multi‑pass welding.
- Welders who need a dedicated plasma cutter with higher cut capacity (e.g., > 1/2″ plate).
- Those who prefer a separate machine for each process due to risk of crossover contamination or convenience.
Expert Tips
- Always select the correct primary voltage (110V or 220V) before connecting power – incorrect selection can damage the unit.
- For plasma cutting, ensure your compressed air supply is clean and dry; water or oil in the air reduces cut quality and consumable life.
- When MIG welding, start with the recommended voltage/wire speed chart in the manual, then fine‑tune inductance to minimize spatter.
- Use the foot pedal for TIG to improve control on thin materials – it allows you to ramp amperage up and down without moving away from the arc.
- Keep extra consumables (contact tips, nozzles, electrodes) on hand – swift replacement keeps projects moving.
Common Mistakes
- Incorrect voltage selection: Failing to switch the internal tap when moving from 110V to 220V outlet can fry the machine.
- Using wrong shielding gas for MIG: For steel, use 75% Argon / 25% CO₂; pure CO₂ is cheaper but produces more spatter.
- Overlooking ground clamp placement: A poor ground connection leads to arc instability and inconsistent welds.
- Cutting too fast or too slow: Plasma cutting speed should be adjusted so the arc penetrates fully without dragging – practice on scrap.
- Neglecting duty cycle: At 200A, the machine likely has a duty cycle around 60% (6 minutes of welding per 10). Exceeding it triggers thermal shutdown.
- Running TIG without a foot pedal: The machine’s built‑in amperage control is less responsive; a pedal greatly improves control.

FAQ
Can the YESWELDER MCT‑520 weld aluminum?
Yes, but for MIG welding aluminum you need a spool gun (sold separately). TIG mode can also weld aluminum with AC current – the MCT‑520 offers HF TIG, but check the manual for AC aluminum capability; the provided specs only mention HF TIG, which typically works on DC. Contact YESWELDER for confirmation.
Does it come with a TIG foot pedal?
No. The foot pedal is an optional accessory sold separately. The machine does have a connector for it.
What is the difference between clean cut and sever cut?
Clean cut (5/16″) refers to the maximum thickness at which you can get a smooth, dross‑free edge at typical travel speeds. Sever cut (5/8″) means the arc can separate the metal, but with a rough edge; it is used for rough cutting.
Is the MCT‑520 suitable for use on a 110V household circuit?
Yes, it operates on both 110V and 220V. However, on 110V the maximum output is lower – you won’t reach 200A welding or 50A cutting. For full performance, a 220V circuit is recommended.
What gases are recommended for this welder?
For MIG: 75% Argon / 25% CO₂ (C25) for steel; 100% Argon for aluminum (with spool gun). For TIG: 100% Argon. For plasma cutting, clean compressed air (at least 60 PSI).
How does the warranty work?
YesWelder provides a 2‑year warranty covering manufacturing defects. They have a North American service center, and support is available 24/7 via phone/email. Claims require contacting support and may involve return authorization.
