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 amperage while welding. Like MIG welding, a shielding gas (typically argon) is required.  View Miller TIG Product Comparison Chart [PDF]
