Hi Guys ive got alot of box and mild steel plates to weld ranging from 5mm up to 10-12mm at the moment ive only got a old sureweld 120 ARC, thats ok for 4mm stuff but even then it cuts out after 10 or 15mins of use (abuse).

Ive been looking at the Oxford welders on MigTigArc's websites, but these are MIGs
i also like the look of the kemppi welders but if im going to splash out on a good welder i want to make sure i get the right one for the job.

So what would be best a modern Arc/Inverter or a good MIG Something like the Oxford270
