GAS INPUT CONNECTIONS

Supply the PRO-CUT 80 with clean compressed air or nitrogen.

•Supply pressure must be between 80 psi and 150 psi.

•Flow rate should be approximately 6.0 cfm (170 I/min.).

NOTE: Oil in the air supply to the PRO-CUT 80 can cause severe problems. Use only a clean air supply.

•Connect the gas supply to the PRO-CUT 80’s pneumatic nipple at the air filter. See Figure A.3.

•Compressed gas should be supplied to the fitting connection mounted on the filter at the rear of the machine. If necessary, this fitting can be removed allowing plumbing access through the 1/4 in. (6.4mm) NPT input port on the filter body.

WARNING

CYLINDER could explode if damaged.

• Keep cylinder upright and chained to a fixed support.

• Keep cylinder away from areas where it could be damaged.

• Never lift machine with cylinder attached.

• Never allow the cutting torch to touch the cylinder.

•Keep cylinder away from live elec- trical parts.

•Maximum inlet pressure 150 psi.

NOTE: When using nitrogen gas from a cylinder, the cylinder must have a pressure regulator.

•Maximum psi from nitrogen gas cylinder to PRO- CUT 80 regulator should never exceed 150 psi.

•Install a hose between the nitrogen gas cylinder regulator and the PRO-CUT 80 gas inlet.
