3.5 Power Supply Input Connections - Gas Supply
Connectors are sized for 3/8” inside diameter hose. Do not change the inlet gas
supply fittings to quick-connect fittings. Using quick-connect fittings to connect and
disconnect pressurized hoses may cause damage to the System. Gas supply hoses
can be supplied as an option. Refer to Figure 3 for the physical location of all
connections.
Make connections in the order shown below.
When making brass
fitting connections, use two opposing wrenches and only tighten enough to make
gas seals. The fittings are subject to damage if over tightened.
Argon Inlet
Argon is optional and provides improved marking capabilities. If not used, this
inlet should be capped.
Nitrogen Inlet
Nitrogen must be supplied for cutting stainless steel and aluminum; not required
for cutting mild steel.
H17 Inlet
H17 gas must be supplied to the unit when stainless steel is to be cut with H17
as the plasma gas. If not used, this inlet should be capped.
Air Inlet
Air must be supplied at all times, except when cutting stainless steel with H17.
Oxygen Inlet
Oxygen must be supplied to the unit at all times for cutting mild steel; not
required for cutting stainless steel or aluminum.
