I have an old syncrowave 250 ac/dc Tig welder. Can someone tell me if it needs single or three phase power supply The name plate says it’s single phase ( but does this mean USA “two” phase or UK single phase). It has a red three phase plug on it with wires going to L1, L2 and earth. and the primary terminal jumper is set to 380v. ( jumpers can bet set to 220v, 380v or 415v). Is it possible to get this to run off UK single phase power supply with jumper set to 220v. ??
Thanks
