I have bought a topweld 180 (there is no other information inside or on the ouside of the box) that is switchable from 240 volts to 415 volts via a rotary switch on the front, It is set up for 240 volts at the moment. I would like to change it to 3 phase, but I do not have the manual for it. I take it that I have to change the connections on the back of the switch and put a 4 or 5 wired cable on in place of the standard 3.
The connections are labelled UT1 A, RL1, U1 T4.
Would be gratefull if anyone can help.
