Tungsten Inert Gas (TIG) welding is a popular type of welding that utilizes tungsten electrodes to join various metals. The tungsten electrode is a critical component in the process, as it channels the current required to establish the arc. The tungsten electrodes can be alloyed with a variety of metals. Different types and sizes of electrodes are used for different types of welds and materials, and welders develop preferences based on welding style and project. Certain electrode types perform better with alternating current (AC) as opposed to direct current (DC). Electrodes are shipped without a ground tip. If grinding a tip, make a tight, sharp point in order to achieve a powerful and precise arc to ensure a clean weld.
