ESAB MIG Welder
MIG (Metal Inert Gas) welding (also known as GMAW - Gas Metal Arc Welding) uses wire fed through a welding 'gun' or 'torch'. The arc is struck between the wire and the workpiece, and shielded by an inert gas pumped through the torch. For more information or an introduction to MIG welding, see the references at the bottom of this page.
Our MIG welder is an ESAB MIG 510W witha separate wire feeder. The feeder is an ESAB MEK 4. The mig torch is a 400 amp water cooled Binzel model.
Current Status
It has been tested, and it welds very nicely. However, the earth clamp and one socket need replacing, as do the feed rollers and contact tip. The feed roller mechanism needs some tuning.
Power Supply
Currently shares a 32A 415V socket with the SMAW (stick) welder. A separate socket will be installed soon.
