Which component is NOT part of a water cooled torch's connection?

In a water-cooled torch used in GTAW, the connection typically involves three main components: electricity supply, shielding gas, and water supply. Each of these plays a crucial role in the welding process.

The electricity supply provides the needed current for the welding arc, allowing the electrode to melt and join the base materials. The shielding gas, often argon or helium, protects the weld pool from atmospheric contamination, which is essential for producing a clean and quality weld. The water supply is vital because it helps to dissipate the heat generated during the welding, preventing damage to the torch and ensuring consistent performance.

The gas supply refers specifically to the flow of shielding gas and does not encompass all the necessary elements of a water-cooled torch setup. While shielding gas is essential for the operation, the term "gas supply" may imply other types of gases or applications not specific to cooling or protecting the arc. Therefore, it is not considered a component of the water-cooled torch connection in this context.
