YESWELDER YWM-200 MIG Welder: up to 200 A, 110/220 V

What it welds

The YESWELDER YWM-200 MIG Welder is a MIG / gas with a maker-stated output of up to 200 amps on 110 or 220-volt input.

Miller's starting rule, 1 amp for each 0.001 inch of steel, puts 200 amps at roughly 0.200 in of steel in one pass; thicker work means bevels and more passes. Run the amperage selector.

The listing doesn't give a duty cycle with its amperage, which makes long beads hard to plan; the rating plate or manual should state it. Why it matters.

It runs solid wire under shielding gas (Gasless) for the cleanest wire-feed welds; most machines like it also run flux-core wire outdoors.

Dual-voltage input gives portability on 120 volts and full output on 240; the maker's ratings for each input differ. 120 V vs 240 V.

Eye protection: OSHA's minimum is shade 10 for most of this machine's range. Full table.

Also on the listing: a weight of 39.2 lb.
