Use the brass tapered retaining cap part no. 020034 above 400 amperes.
To obtain optimum cut quality, plasma arc cutting nozzles are usually operated at an arc current slightly below the
level that results in double-arcing. Attempting to operate nozzles above the maximum limit will cause a deterioration
in performance.
The conditions listed above are chosen for optimum cut quality (not speed) and will generally produce excellent
results. If deviations from these conditions are necessary, they should be limited to changes in arc current, arc
voltage, and travel speed. These parameters have a significant effect on cut quality. Do not deviate from specified
gas and water flows.
