Using this Lincoln Caliber Collet Body is easy. First, make sure your TIG torch is turned off and cool. Then, insert the collet body into the appropriate place in your 9/20 TIG torch. Next, place the tungsten electrode into the collet body. It will hold the electrode securely. When welding, the collet body will direct the gas to the weld puddle for a better result. As for maintenance, after each use, clean the collet body gently with a soft cloth. Avoid using abrasive materials that could damage the copper alloy body. Also, keep it in a dry place. If you notice any signs of wear or damage, replace it right away to ensure continued good performance.
