Powerfist/Princess Auto MIG

Has anyone ever used the 220V MIG sold at Princess Auto? It's made by
PowerFist which I believe is their offshore import house brand. The unit
has a 3/16" barb for a gas regulator and it comes with the gauges. I need
it to do some light body work and maybe the odd exhaust repair. At this
point I can't commit to a high end machine so I wanted to know if anyone had
feedback on this one???

Thanks.
Andrew.
