80 – 100 psi (5.5 – 6.9 bar) gas supply
(maximum 135 psi or 9.3 bar)
Connection
Connect the gas supply to the system using an inert gas hose with a 3/8 inch (9.5 mm) internal
diameter and a 1/4 NPT quick-disconnect coupler. The Powermax30 consumables kit includes a
1/4 FPT x 1/8 NPT air fitting reducer as well.
Gas supply
The gas supply for the Powermax30 can be shop-compressed or cylinder-compressed. A high-
pressure regulator must be used on either type of supply and must be capable of delivering gas to
the filter on the power supply at
3.5 scfm @ 65 psi (99.1 l/min @ 4.5 bar) . To ensure adequate
pressure to the power supply, set the regulator to 80 to 100 psi (5.5 to 6.9 bar).
If gas supply quality is poor, cut speeds decrease, cut quality deteriorates, cutting thickness
capability decreases, and the life for consumables shortens.
Optional reducer
WARNING
Do not allow the gas supply pressure to exceed 135 psi (9.3 bar). The filter bowl may
explode if this pressure is exceeded.
Caution: Synthetic lubricants containing esters that are used in some air
compressors will damage polycarbonates used in the air
regulator bowl.
