That would be really cool. This is one of the inverter arcs I've spotted but not sure about it on a 13 amp domestic plugAnyone close to L2wis (Leicestershire) who could give him a shot on MIG or ARC?

There is a 80 amp version too but I'm thinking that might be too limiting. I'm gutted I missed out on a cheap £30 sip.
