How many hoses does a water cooled torch have connected to the power source?

In a water-cooled torch used in Gas Tungsten Arc Welding (GTAW), there are typically two hoses that connect to the power source. These hoses are designed for the cooling system of the torch. One hose carries the coolant from the power source to the torch, while the other returns the heated coolant back to the power source.

While the answer provided states three hoses, this typically isn't the standard configuration for a water-cooled setup in GTAW. Instead, the common practice is to have just these two hoses to ensure efficient cooling during the welding process, which helps to maintain torch performance and prevent overheating. Hoses are essential in managing the thermal load experienced during welding, ensuring consistent operation and enhancing the lifespan of the torch.
