I sold my inverter machine to buy a three phase arc welding machine because I read it's more solid, but I can't figure out how to wire it, the seller is clueless he doesn't know what is the difference between three phase and single phase, the manual is in Chinese with bad translation to English and for a different model; I returned it to the seller, and I tried to find another one but I couldn't find any three phase AC arc welder there are only single phase welders so I bought it back from the same seller again. The model is BX1-250 "BX1 Series" it has two inputs "1" for 240V and "2" 380V. I think I should connect N-L1 in input 1 and L2-L3 in input 2, but I'm afraid I'm going to toast it. Anyone is familiar with these AC ARC welding Machines?
