YesWelder welders: what the manuals say about power, duty cycle and support

YesWelder sells inverter welders, plasma cutters and helmets direct and through Amazon, at a fraction of what Hobart, Lincoln and Miller charge. The question for a buyer is not whether the brand is real. It is whether the numbers are published, and what they mean for your garage.

YesWelder is more open than most budget brands about what its machines draw: the manuals print both nameplate input currents for every process. Those currents are 29 to 54 amps on a 110 volt supply, well beyond a household outlet. YesWelder publishes no breaker, wire or generator guidance, so your electrician works from the nameplate alone.

The machines we have checked

All figures from YesWelder’s own manuals and product pages, checked 2026-09-19. I1max is the most the machine draws from the wall at its maximum rated output. Duty cycle is the share of ten minutes it can weld before cooling: see duty cycle as minutes of arc.

Model	Processes	Rated output, 110 V	Rated output, 220 V	I1max, 110 V / 220 V
FLUX-135PRO	Flux core, stick, lift tig	135 A at 60 percent	110 V only	54 A
MIG-205DS PRO	Gas mig, flux core, stick, lift tig, spool gun	160 A at 60 percent (mig)	205 A at 60 percent (mig)	43 A / 34 A
MCT-520	Mig, flux core, high frequency tig, stick, 50 A plasma cut	130 A at 60 percent (mig)	200 A at 60 percent (mig)	37 A / 41 A (mig); 45 A / 43 A (stick)

Two things stand out. Every machine claims 60 percent at its full output, which is two to three times what Hobart and Lincoln publish for comparable machines. And every machine asks far more of a 110 volt supply than a household circuit gives.

What YesWelder publishes, and what it does not

Published: output range per process, duty cycle at a stated amperage and voltage (at both the 60 and 100 percent points), I1max and I1eff per process, open circuit voltage, an operating temperature range of 14 to 104 F, and downloadable manuals for each product.

Not published, in the documents we read:

• The temperature or standard the duty cycle was rated at. The international standard, IEC 60974-1, uses 40 C (104 F). YesWelder gives 40 C as an operating limit without tying the rating to it. Until it does, we cannot say its 60 percent is measured the same way as a Hobart’s 30.
• A recommended breaker, supply wire gauge or generator size.
• What output is available on a 15 or 20 amp circuit.
• For the MCT-520 cutter, a consistent cut rating. The product page and the maker’s own setting chart disagree on clean cut, sever cut and air pressure. We print the lower figures in plasma cutters explained.

One more finding from the FLUX-135PRO manual: it says not to use the machine on a GFI outlet. Many garages have exactly those.

What this means for your garage

If you have, or will add, a 240 volt circuit, a YesWelder dual voltage machine gives a lot of published capability for the money. If you have only household outlets, expect reduced output and tripped breakers when you turn it up. The arithmetic is in welder amp draw and 110v vs 220v welders.

Either way, download the manual for the exact model, find the spec table, and take I1max and I1eff to a licensed electrician. We do not publish wiring instructions.

Warranty, parts and support

• Warranty. Two years is stated on the product pages for the welders above. Helmets get one year under the warranty policy page.
• Manuals. Available by product on yeswelder.com, which is better than several rivals manage.
• Parts. YesWelder sells helmet lens packs and accessories on its own site, and a spool gun for its mig models. Check the manual for your model’s contact tip and nozzle type before buying spares, because the manuals we read do not all name the pattern.
• Helmets. The product page for the popular LYG-M800H names no safety standard. We explain why that kept it out of our ranked list in best welding helmets.

Where YesWelder machines rank on this site

The MIG-205DS is our top pick in best multiprocess welders, with the MCT-520 as the welder and cutter combo. The FLUX-135PRO is the low cost pick in best welder for beginners, with its 54 amp input stated plainly. The MIG-250 PRO is in best mig welders and the multiprocess list. All three sit beside Hobart, Lincoln, ArcCaptain and Weldpro machines in the welder comparison table.
