LOTOS MIG175 MIG Welder: up to 175 A, 240 V

What it welds

The LOTOS MIG175 MIG Welder is a MIG / gas with a maker-stated output of up to 175 amps on 240-volt input.

Miller's starting rule, 1 amp for each 0.001 inch of steel, puts 175 amps at roughly 0.175 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.

It runs solid wire under shielding gas (Gasless) for the cleanest wire-feed welds; most machines like it also run flux-core wire outdoors.

Plan a 240-volt circuit sized as the manual states before it arrives. 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: dimensions of 18 x 12.5 x 10.5 inches and a weight of 38.9 lb.
