Use the brass tapered nozzle retaining cap – part no. 020034
High Current Cutting is conventional cutting. It does not use the Water-Injection principle. The water sprayed from
the nozzle is for nozzle cooling purposes only. It does not constrict the arc.
Always remove the Water-Muffler and lower the water level in the Water-Table when operating in the High Current
Mode.
Caution:
Use of the Inductive IHS at high currents may damage the Inductive probes due to the high
amount of reflected heat and ejected metal during the pierce process.
Warning:
The plasma console is not vented for combustible gases. The optional ARGON/HYDROGEN
MANIFOLD part number 028057 is required when using Argon/Hydrogen gas mixtures.
Caution:
Never operate Water-Injection nozzles with Argon/Hydrogen gas mixtures.
