YESWELDER 250A Multi-Process Welder: up to 250 A, 110/220 V

What it welds

The YESWELDER 250A Multi-Process Welder is a multi-process with a maker-stated output of up to 250 amps on 110 or 220-volt input.

At its top output of 250 amps, Miller's 1-amp-per-thousandth rule points to about 1/4 in of steel per pass. Where the rule comes from.

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/Flux Core/Spool Gun. Most multi-process machines' TIG is DC lift-arc, so no aluminium unless AC is stated. Choosing a process.

Running on 120 or 240 volts, it trades output for convenience on the lower input. What input voltage changes.

Use a lens of at least OSHA's minimum shade for the current: shade 10 or darker for typical MIG work here. Shade chart.

Also on the listing: a weight of 37.6 lb.
