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 LAW 500W 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 lead needs work (underway at the moment), and the feed rollers and contact tip need replacing. 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.
Controls
This is the power switch (the larger one on the right) and the switch for the water cooling pump (the smaller one on the left).Running the water cooling pump without a torch attached will damage the pump. The pump needs to be able to circulate through something.
