Using this Lincoln Caliber Collet Body is easy. First, make sure your TIG torch is turned off. Then, insert the tungsten electrode into the collet body. Place the collet body back into your 17/18/26 TIG torch. When you start welding, the collet body will direct the gas to the weld puddle. Remember to always wear proper safety gear. After each use, let the collet body cool down. Clean it gently with a soft cloth to remove any debris. If you notice any signs of wear, it's a good idea to replace it to keep your welding work in top shape.
