TIG (GTAW)

TIG (tungsten inert gas) welding is used to make precise, critical welds when joining metals such as mild steel, aluminum, or stainless steel. TIG welding is a two-handed process (one hand holds the torch while the other feeds filler metal) and commonly involves a foot pedal or fingertip remote to control the arc voltage while welding. Like MIG welding, a shielding gas (typically argon) is required.
