What it welds

The Everlast PowerTIG 255EXT AC/DC TIG Welder is an AC/DC TIG on 240-volt input; its listing doesn't state an output range, so check the rating plate.

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's AC/DC, so it can weld aluminium as well as steel and stainless. Pulse: ac pulse.

It needs a 240-volt circuit; have a licensed electrician install the receptacle the manual specifies. 120 V vs 240 V.

Eye protection: OSHA's minimum is shade 8 for most of this machine's range (shade 10 for stick above 160 A). Full table.

Also on the listing: dimensions of 22 in (L) x 9 in (W) x 17 in (H) and a weight of 85 lb.
