A TIG torch can be either water cooled or air cooled and is designed to provide shielding gas as well as welding current through a tungsten electrode. A ceramic nozzle directs the shielding gas to the weld puddle and internal copper parts like the collet and collet body hold the electrode in place. The tungsten electrode is sharpened for applications where the arc needs to be pinpointed and for very low amperage. One of things that is importatnt to know before you buy a cheap TiG welder is how it works. Understanding a few basic things can really help keep things from falling apart, and help if something goes wrong.
