AIR INPUT CONNECTIONS

Supply the PRO-CUT 60 with clean compressed
air or nitrogen.
• Supply pressure must be between 70 psi
and 120 psi (482 kPa and 827 kPa).
• Flow rate should be approximately 4.7
cfm (133 I/min.).
NOTE: Oil in the air supply to the PRO-CUT 60
can cause severe problems. Use only a clean air
supply.
1. Connect the air supply to the PRO-CUT 60
regulator.
a. Remove the plastic thread protector from
the machine's regulator input port located

ulator with an appropriate gas connection
fitting. Sealing the connection with Teflon
tape is recommended.
2. Tighten the air fitting connection to prevent
leakage.
-Do not overtighten.
NOTE: When using nitrogen gas from a cylinder,
the cylinder must have a pressure regulator.
• Maximum psi from nitrogen gas cylinder to
PRO-CUT 60 regulator should never
exceed 120 psi (827 kPa).
• Install a hose between the nitrogen gas
cylinder regulator and the PRO-CUT 60
regulator's gas inlet.
