Chamfering and gouging of both ferrous and non-ferrous metals. When chamfering and beveling cast iron, it not only produces a clean groove but the arc "sears" the base metal and burns out grease, oil, moisture and some of the excess carbon. On stainless steel, this electrode is superior to oxygen/fuel torches that use mild steel rods or powders because 1.)there is less oxidation of the weld zone since it is surrounded with ionized metal instead of oxygen; 2.)less carbide precipitation because the chamfering speed is so fast, the weld area is held at the critical heat range for a shorter time. No air or special equipment is needed.

Procedure

The use of DC straight polarity will produce the cleanest, fastest grooves, but AC may be used. Hold electrode at a low angle to the work (between 7 and 15 degrees)Strike the arc, point electrode in the direction of travel, and push the electrode along the line to be cut. Keep the electrode in contact with the work and move as fast as possible. If a deeper cut is required, repeat in the same groove until desired depth is reached.
