About TIG Back Caps

TIG back caps are welding torch and gun components that shield the back of the tungsten electrode. Buyers check several details before buying these parts. A buyer checks the torch model to ensure proper compatibility. The buyer verifies the correct torch series and accessory setup. A buyer selects the appropriate length, such as long, medium, or short options. Manufacturers supply parts that must match the front end design of the torch. The buyer checks the electrode diameter and the manufacturer part number. The buyer matches these items to prevent unusable stacks. The buyer reviews the verified combination of the torch model, the collet, the insulator, the cup, and the back cap.
