i have a parweld 140XTI its just scratch start, up to 140amp, gas is regulated by a valve on the torch, only really ment to use it to 110amp on 13amp plug and need 16 amp to use the full 140, and you can use it for arc welding had that at 120amp in 13a with no probs.
i leaned to weld on a 3phase Kemppi 2200 with hf, great unit. sadly company went under, so i got myself somin cheap in case i wanted to do some tig.
think my parweld is about £180 ish
