Components of a Welding Torch

Handle
The handle is the part of the torch that the welder holds. It’s designed for comfort and control during welding operations. The handle often contains switches or triggers to control gas flow and, in some cases, arc initiation.

Body
The torch body houses the internal components and provides structural support. In water-cooled torches, the body contains channels for coolant circulation.

Collet
The collet is a holding device that grips the tungsten electrode. It ensures proper electrical contact and alignment of the electrode.

Collet Body
The collet body holds the collet and helps direct the shielding gas around the electrode.

Gas Nozzle (Ceramic Cup)
The gas nozzle, often made of heat-resistant ceramic, directs the flow of shielding gas around the weld area. It comes in various sizes to suit different welding applications.

Tungsten Electrode
In TIG welding, the tungsten electrode carries the electrical current to create the arc. It’s non-consumable and comes in various types and sizes for different welding tasks.

Back Cap
The back cap covers the rear of the torch, protecting the tungsten electrode and allowing for easy electrode changes.

Gas Diffuser
In some torch designs, a gas diffuser helps distribute the shielding gas evenly around the electrode.

Power Cable
The power cable delivers electrical current from the power source to the torch.

Gas Hose
The gas hose connects the torch to the shielding gas supply.
