gas Purging:
When switching between H-35 and an oxidizing gas (air or oxygen) it is recommended that the following procedure be
followed:
1 . Turn off the gas .
2 . Put the system into plasma gas test until line pressure is exhausted . If the start gas is being switched to or from
H-35, switch to start gas test until that line is exhausted as well .
3 . Disconnect the old gas and connect a relatively inert gas such as nitrogen, argon, carbon dioxide, C-25, etc . Set the
pressure to 50 psig (3 .5 bar) and purge each affected line for 60 seconds .
4 . Then shut off the gas and exhaust each line per Step 2 .
5 . Connect the gas to be used . Set the pressure to recommended values for the cutting condition to be used, and
purge each affected line for 15 seconds per 25 ft . (7 .6 m) of line .
