MIG Welding Torch Operation

Wire Feed: The consumable wire electrode is continuously fed through the torch.

Arc Initiation: The welder pulls the trigger, starting the wire feed and gas flow, and touches the wire to the workpiece to start the arc.

Arc Maintenance: The wire feed speed and voltage are set to maintain a stable arc.

Shielding: Gas flows through the torch nozzle, protecting the weld area.

Welding: The welder moves the torch along the joint, with the wire continuously melting and joining the base metals.
