AHP AlphaTIG 203Xi AC/DC TIG Welder: 220 V

What it welds

The AHP AlphaTIG 203Xi AC/DC TIG Welder is an AC/DC TIG on 220-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.

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

It's AC/DC, so it can weld aluminium as well as steel and stainless. Pulse: 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 19 x 23 x 12 inches and a weight of 69 lb.
