A balled tip is generally used for pure tungsten electrode
and is suggested for use with the AC process on sine wave and conventional
square wave TIG welders. To properly ball the end of the tungsten, simply apply
the AC amperage recommended for a given electrode diameter and the ball on the
end of the tungsten will form itself. The diameter of the balled end should not
exceed 1.5 times the diameter of the electrode (for example, a 1/8-in.
electrode should form a 3/16-in. diameter end), as having a larger sphere at
the tip of the electrode can reduce arc stability and/or fall off and
contaminate the welding.
