The Diamond Ground Products Piranha III (DGP-PG3-A) is a heavy-duty, high-precision tungsten electrode grinder engineered for TIG welding (GTAW) applications. Powered by a 1/3 HP motor (120V AC, 60 Hz), it features a universal collet arm that handles six tungsten electrode diameters (.040 in to 3/16 in) with no tool changes required. It provides longitudinal 20 Ra grinding, an adjustable grinding angle scale from 10° to 60°, an integrated electrode notching/cut-off station, and a sliding dust shield for 100% dust containment.
