233-P-US02455 ELECTRODE DRIVE AND NOZZLE SYSTEM FOR AUTOMATIC AIR-CARBON ARC CUTTING AND GOUGING TORCH ABSTRACT OF THE INVENTION An automatic air-carbon arc cutting and gouging torch having drive means for the elongated electrode consisting of opposed wheels biased toward the electrode for frictional contact to drive the electrode by driving one of the wheels. Each wheel can be adjusted about a pivot point to compensate for curvature of the electrode, changes in diameter, or mis-aligned joints in successive electrodes. The torch includes an improved nozzle to conduct both current and process air to the electrode thus lower- ing the operating temperature of the torch.
