Maximum current for this nozzle is 750 amp.
Use the brass tapered retaining cap part no. 020034 above 400 amperes.
When cutting materials greater than 1-1/2 inches (40mm) thick, lower the level of water in the water table to
3 inches (75 mm) below the lower surface of the workpiece. Also de-energize the Water Muffler pump to improve
arc penetration.
For cutting thicker plate refer to the chart Operating Data for High Current Cutting on page 4-10.
