What it welds
The Weldpro 155 Multi-Process Welder is a multi-process with a maker-stated output of up to 155 amps on 220-volt input.
By Miller's rule of thumb of 1 amp per 0.001 inch of steel, 155 amps reaches about 5/32 in in a single pass. Amps by thickness.
The maker's thickness claim reads "up to 1/4" steel". Makers often mean multiple passes or flux-core wire when a claim runs past the amps rule; the wording here says which.
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/MMA/Stick. Check which torches and guns come in the box; a TIG torch or spool gun is often extra. Process guide.
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 10 for most of this machine's range (shade 10 for stick above 160 A). Full table.
Also on the listing: dimensions of 14.96 x 13.58 x 6.69 inches and a weight of 21.2 lb.
