Semi Automatic MIG (Metal Inert Gas) welding is an Electric Arc Fusion process using bare or flux cord wire with a gas shield of argon or CO2 or mixture of gases to protect the weld pool for atmosperic contamination.
The equiptment comprises of a D.C. constant potential or variable characteristic power source, a wire feed unit and torch. The electrode wire passses through the torch and on touching the work -piece an arc is established. The arc voltage is maintained constant automatically resulting in better quality welds with minimum welders skill.
D.C. Power Sources : GR-200/GR-400/GR-600.
The Power Sources are designed for use with a MIG Wire Feeder Unit, Thyristor controlled for spray transfer MIG Welding.
Available for current upto 600 Amps; an Auxiliary Internal provision
