Using these Lincoln Caliber Collets is easy. First, make sure your TIG torch is the 17/18/26 type. Select the right size collet according to your welding needs, which range from.020' to 5/32' (0.5 - 4.0 mm). Insert the tungsten electrode into the collet and then place it in the torch. When using, avoid overheating the collet for too long, as it may reduce its lifespan. After use, clean the collet gently with a soft brush to remove any debris. Store it in a dry place to prevent corrosion. This way, you can keep your collets in good condition and get the best performance out of them every time you weld.
