Arc Gouging Equipment

"Gouging" is a technique that liquefies metal in a narrow groove and then removes it using compressed air. Gouging products are often used in joint preparation prior to a welding process. Numerous other applications exist for these gouging systems, such as removal of defective welds, removal of trim in foundries and repair of track, switches and freight cars in the railroad industry. The air carbon-arc process (CAC-A) remove metal physically, not chemically (as in oxy-fuel cutting - OFC). Gouging or cutting occurs when the intense heat of the arc between the carbon electrode and the workpiece melts part of the workpiece. Meanwhile, air passes through the arc quickly enough to blow the molten material away.
