Weldpro ACDC 250GD AC/DC TIG Welder: up to 250 A, 220 V

What it welds

The Weldpro ACDC 250GD AC/DC TIG Welder is an AC/DC TIG with a maker-stated output of up to 250 amps on 220-volt input.

Miller's starting rule, 1 amp for each 0.001 inch of steel, puts 250 amps at roughly 1/4 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.

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.
