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:
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
