Hi I'm looking at buying a new MIG, I do some blacksmithing and have been using a little arc inverter for a few years to make jigs etc but want to upgrade to a half decent MIG to make life easier. Wondering if the Sealey at £375 is a decent machine or is the R-tech worth spending the extra £100 on? I can buy the Supermig locally if support is required and I know r-tech support is very good. An suggestions? Thanks
