YESWELDER 165A Multi-Process Welder: up to 165 A, 110/220 V

What it welds

The YESWELDER 165A Multi-Process Welder is a multi-process with a maker-stated output of up to 165 amps on 110 or 220-volt input.

By Miller's rule of thumb of 1 amp per 0.001 inch of steel, 165 amps reaches about 0.165 in in a single pass. Amps by thickness.

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.

Processes, per the maker: MIG/Gas MIG/Stick/Lift TIG. Check which torches and guns come in the box; a TIG torch or spool gun is often extra. Process guide.

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 (shade 10 for stick above 160 A). Full table.

Also on the listing: a weight of 25.8 lb.
