How many cables do water-cooled GTAW torches generally have?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (C)

Water-cooled GTAW (Gas Tungsten Arc Welding) torches typically have three cables. These cables serve essential functions in the welding process. One cable is for electrical power, which carries the welding current needed to create the arc between the tungsten electrode and the workpiece. The second cable is for the water supply; this cable is connected to a coolant source, allowing water to flow through the torch to dissipate heat generated during welding. The third cable is a return line or hose that helps circulate the coolant back to the reservoir, maintaining an effective cooling system throughout the welding operation. Having these three distinct cables ensures the efficiency and safety of the GTAW process, allowing for prolonged use of the torch without overheating. Proper cooling is crucial because excessive heat can damage the torch components and affect weld quality.
