SETUP
Air and Gas Supply Requirements
If making hard plumbing connections, avoid using iron pipe. Never use PTFE tape on any joint preparation. After
installation, pressurize the entire system and check for leaks.
Air Supply
Two different sources of air can be used to supply the plasma and shield gas requirements of the MAX200: cylinder
compressed air or shop compressed air. Use an inert gas hose to connect the air supply to the input connection on the
filter/pressure regulator mounted on the rear of the power supply.
Cylinder Compressed Air
The cylinder air supply must be clean, dry and oil-free. A high-pressure regulator on the cylinder must be used and must
be capable of delivering air at a pressure of between 110 and 130 psi to the filter/pressure regulator on the power
supply. The filter/pressure regulator must be set for a 90 psi input to the power supply (refer to the procedure below).
Refer to Section 4, Cut Charts for detailed information.
Shop Compressed Air
The shop air supply must be clean, dry and oil-free. Shop air must capable of delivering air at a pressure of between
110 and 130 psi to the filter/pressure regulator on the power supply. The filter/pressure regulator must be set for a 90
psi input to the power supply (refer to the procedure below). Refer to Section 4, Cut Charts for detailed information.
WARNING
Do not exceed 150 psi to the filter/pressure regulator when using cylinder compressed air or
shop compressed air. The plastic filter bowl may explode if this pressure is exceeded, causing
serious injury. See the warning label on the filter bowl for other safety warnings.
