Functions of a Welding Torch

Heat Generation: The primary function of a welding torch is to generate and direct heat to melt the base metals and, when used, the filler material.

Gas Delivery: In many welding processes, the torch delivers shielding gas to protect the weld pool from atmospheric contamination.

Filler Material Delivery: Some welding torches are designed to feed filler material into the weld pool automatically.

Arc Control: In arc welding processes, the torch helps control the electrical arc that generates the heat for welding.

Precision: Welding torches are designed to allow welders to direct heat and filler material with precision, enabling accurate and high-quality welds.
