Tungsten Tig Electrodes

Two key types of Tungsten Tig Welding Electrode are available, Thoriated (red tip) for DC Tig Welding applications and Zirconiated (white tip) for AC Tig Welding applications. When a Tig Welder is in AC welding mode, the welding arc will cause the tungsten to "ball" at the end. The diameter of this ball should not exceed the diameter of the tungsten, if it does a larger tungsten should be used. When a Tig Welder is in DC welding mode, the tungsten should be ground to a point. This point should be as sharp as possible with the grinding lines running from the point, down the length, NEVER around the point.
