Welding Gun

A welding gun, or torch, is a specialized tool for fusing metal by applying intense heat, melting it to create a joint. It directs an electrical current, and often a consumable wire electrode and shielding gas, to a specific point. The gun typically includes a handle, trigger, nozzle, and contact tip, and is a key component of processes like MIG welding, where it feeds a continuous wire, and is used in applications ranging from auto repair to industrial manufacturing.
