Sep 10, 2018 · 2% Thoriated Tungsten Electrodes Red Tip are available in a number of diameters and sold in packs of 10. Used to strike and maintain a TIG welding arc. Red Tip 2% Thoriated tungstens are used when tig welding mild and stainless steel. You would be welding in DC negative mode. Guidelines To Gas Tungsten Arc Welding (GTAW)Guidelines for preparing a tungsten for AC TIG welding are:Select a tungsten with 2% cerium (2% thorium as your second choice). Grind the electrode to a point (grind in the long direction, make the point roughly two times as long as the diameter).
- Pure TungstenThoriatedCeriatedLanthanatedZirconiatedRare EarthTungsten Preparation Balled, Pointed, Or truncated?After selecting a type of electrode, the next step is to select an end preparation. The three choices are balled, pointed, and truncated. A balled tip generally is used on pure tungsten and zirconiated electrodes and is suggested for use with the AC process on sine wave and conventional square wave GTAW machines. To ball the end of the tungsten properly, simply apply the AC amperage recommended for a given electrode diameter (seeFigure 1), and a ball will form on the end of the eleHow to Correctly Grind, Cut & Prepare Tungsten Welding Cut tungsten electrodes .040/.062 diameter with wire cutters or used their hands. Cut tungsten electrodes 3/32 to 1/8 diameter by using 2 pairs of pliers and a twisting motion or notched the electrode on the grinding wheel and used two pairs of pliers. Cut tungsten electrodes over 1/8 diameter using a sharp hammer blow to the electrode on
