Additional Air Filtration
Use a three-stage coalescing filtration system as shown in Fig. 3-12 when site conditions introduce
moisture, oil or other contaminants into the air line.
Nitrogen Supply Quality
Nitrogen must be supplied to the Powermax1100 at 99.995% purity. If the purity level of the nitrogen is
too low, cut speeds decrease, cut quality deteriorates, cutting thickness capability decreases, and parts
life shortens. (Note: These conditions also occur if there are leaks in the gas supply hoses or
connections.) The nitrogen supply can be compressed gas cylinders or liquid containers.
GAS SUPPLY CONNECTION
Use a 3/8 inch (9.5 mm) ID inert gas hose to connect the gas supply (air or nitrogen) to the power
supply filter. To connect the hose, install a 1/4 NPT nipple to the filter block as shown in Fig. 3-13.
Apply liquid pipe sealant to the threads to ensure a leak-free installation. A nipple and adapters are
included in the consumable parts kit.
CAUTION: Never use Teflon tape when installing the nipple or adapters. Bits of tape can break off
and enter the air line and harm the pressure regulator, pressure switch and valve.
