Gas Pressures, Flows, and Quality Requirements
Note 2: The tap water source does not need to be deionized, but in water systems with
extremely high mineral content a water softener is recommended. Tap water with high levels of
particulate matter must be filtered.
Note 1: The air source must be adequately filtered to remove all oil or grease. Oil or grease
contamination from compressed or bottled air can cause fires in conjunction with oxygen.
8. Parts - In - Place (PIP)
The torch is designed for use with a power supply which senses coolant return flow to confirm that torch parts are
in place. If coolant return flow to the power supply is absent or insufficient the power supply will not provide
power to the torch. Coolant leakage from the torch also indicates that torch parts are absent or installed improperly.
9. Type of Cooling
Combination of gas stream through torch and liquid cooling.
