Follow the advice presented here to optimize the life of your plasma-arc-cutting consumables-swirl ring, retaining cap, electrode, nozzle orifice and more - and ensure optimum and consistent cut quality. Buildup of dirt, grease and metal dust from daily use can easily clog the small holes in the swirl ring and inner retaining cap. These holes are of a specific diameter and direction as to create a vortex of plasma and shielding gas, to constrict the arc. Contaminated holes will cause the plasma arc to become skewed, resulting in poor cut quality. Wipe down pieces with a clean shop towel every time they are removed from the torch. When not in use, properly store the swirl ring and retaining cap away from contaminants.
