| The parts within the SG-100 are designed to be self-aligning and assembled easily and quickly while maintaining concentricity; i.e., the center line of the electrode on the axis of the nozzle (anode). The more precise this alignment is, the more centered the arc is within the nozzle. Good concentricity and proper gas flow patterns produce: • Minimum heat loss to the nozzle • Long nozzle (anode) life • Simpler more reliable powder injection into the plasma stream • Minimal nozzle powder buildup • Improved coatings (through improved powder injection, maximum heat to the powder and symmetrical arc position on the axis of the anode). |
