Use only clean, dry air with 90 to 120 psi (621 to 827 kPa) pressure. Prevent moisture from entering air supply at extreme cold temperatures. 3 Gas/Air Inlet Opening 4 Hose Hose must have a minimum inside diameter of 3/8 in (9.5 mm). 5 Teflon Tape Obtain hose with 1/4 NPT righthand thread fitting. Wrap threads with teflon tape (optional) or apply pipe sealant, and install fitting in opening. Route hose to gas/air supply. Or Install supplied quick connect male 1/4 in NPT pipe fitting. Connect female quick connect fitting to pipe fitting. Route hose to gas/air supply. Incorrect plasma gas can cause torch and power source damage. Use only air or nitrogen for the plasma gas.

If a flexible cord or cable is used, minimum conductor size may increase. See NEC Table 400.5(A) for flexible cord and cable requirements. . Caution: Failure to follow these fuse and circuit breaker recommendations could create an electric shock or fire hazard. 4-8.

Selecting A Location And Connecting Input Power 1 Plug (NEMA Type 6-50P) 2 Receptacle (NEMA Type 6-50R) Connect plug to receptacle. 3 Input And Grounding Conductors For single-phase operation: Make input power connections to the machine before making connections into a deenergized line disconnect device. In the line disconnect device, always connect green or green/yellow grounding conductor to supply grounding terminal first, never to a line terminal. Connect directly to line disconnect device if hard wiring is required. 4 Line Disconnect Device See Section 4-7.
