Tig (Argon Arc) Manual Welding Equipment .
|
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

given for supply to the Wire feeder Unit Attachment & to the CO2 heater. The welder has available delay drop out to adjust the desired burnback.
WIRE FEEDERS :
Wire feeder Units are Portable Units having Twin. Roll Drive system designed to feed 0.8 to 2.4mm dia. welding wires to a hand operated MIG welding Torch.
For ease in installation & operation as well as maintenance the Wire feeders are compartmentalized for different circuitery/ parts for different operations. Maintenance is made easy with Plug-in type printed circuit Boards (PCBmodules). A specially designed hub Assembly at the rear of the Wire feeder Units, accomodates a standard 12" dia. reel of welding wire.
The wire feeder units are fully solid state & Thyristor controlled, has in addition latching facility, fine control & overload protection.
