Welding Torch (Gun)

A critical component of welding systems that serves as the operator's interface for directing heat and material to create welds. As part of the Welding Power Source & Torch system, it connects to the power source via cables and typically includes a handle, trigger mechanism, nozzle, and consumable parts like contact tips and gas diffusers. It precisely controls the delivery of electrical current, shielding gas (in processes like MIG/TIG), and filler wire to create controlled fusion between metal workpieces.

The welding torch receives electrical current from the power source and channels it through a contact tip to create an arc with the workpiece. In gas-shielded processes, it simultaneously delivers shielding gas through a nozzle to protect the molten weld pool from atmospheric contamination. For wire-fed processes, it mechanically feeds consumable electrode wire through the torch body to the arc zone. The operator controls arc initiation, wire feed, and gas flow via trigger mechanisms while manually manipulating the torch position.
