A hand-held torch is great for cutting quickly through sheet metal or gouging and removing defective welds or for back-gouging. It's good for cutting small shapes from steel plate, however it does not provide good enough edge quality and part accuracy for most metal fabrication applications. For accurate, clean cuts, use a CNC plasma machine.
Extreme angle-arc gouging torches and extreme straight handle gouging torches speed up weld removal, back-gouging, edge preparation, defect repair and many other metal removal jobs. They are ideal for almost all metals with little or no deformation because the heat input is so low.
The SYMEX SEMI-AUTOMATIC GOUGING TORCH is used by metal fabricators to make machine-like "U" or "J" grooves in light or heavy plate, flat or round. The "Star-Trac" grooves, bevels, gouges, or cuts any kind of metal quickly and at a low cost.
Jun 08, 2004· Plasma arc gouging is one of four common gouging methods. The others are mechanical, oxyfuel, and air carbon arc gouging. Mechanical Gouging. Mechanical gouging methods—grinding, hand milling, routing, and chipping—are widely used. These methods are suitable for metalworking shops, but typically they are slow and often loud. Oxyfuel Gouging.
Back Gouging: The removal of weld and base metal by arc gouging or grinding from the other side of a partially welded joint to assure complete fusion and penetration upon subsequent welding from that side. ... welding machine when no current is flowing in the welding circuit.
Air carbon arc gouging works as follows. An electric arc is generated between the tip of a carbon electrode and the workpiece. The metal becomes molten and a high velocity air jet streams down the electrode to blow it away, thus leaving a clean groove.
