17F-25 Standard TIG Torch

A 17F-25 Standard TIG torch is a type of welding torch commonly used in Tungsten Inert Gas (TIG) welding processes. Here is a description of its key features and components:

1. Handle/Grip: The torch handle is typically made of heat-resistant materials and designed for a comfortable grip. It often includes a trigger or button for controlling the flow of shielding gas and the welding current.

2. Cable: The torch is connected to the welding machine via a flexible cable that carries both the electrical current and the shielding gas. The cable is usually made of durable, insulated materials to withstand the harsh welding environment.

3. Head/Body: The head or body of the torch contains the consumables and components necessary for the welding process. It typically includes:

   • Gas Nozzle: The gas nozzle directs the flow of shielding gas to protect the weld area from atmospheric contamination. It can vary in size and shape depending on the specific welding application.

   • Collet: The collet holds the tungsten electrode in place. It is an essential component for maintaining a stable and precise arc.

   • Collet Body: The collet body threads onto the torch head and secures the collet and tungsten electrode. It also provides electrical contact for the electrode.

   • Tungsten Electrode: The tungsten electrode is the non-consumable electrode used in TIG welding. It can withstand high temperatures and is essential for creating the arc that melts the base metal.

   • Back Cap: The back cap secures the collet body and provides electrical contact. It can be removed to access the collet and tungsten electrode for maintenance.

4. Trigger/Button: The torch often includes a trigger or button that the welder can press to initiate the welding process. This control allows the welder to start and stop the welding arc easily.

5. Gas Hose: The gas hose is connected to the torch handle and delivers the shielding gas from the gas source to the gas nozzle on the torch head.

6. Power Connector: At the other end of the cable, there is a power connector that plugs into the welding machine's power source. This connector allows the welding machine to provide the necessary electrical current to the torch.
