(PSR), Full CNC Available with Remote
8. Coolant Pressure
Internal Service-adjustable
130 psi (8.8 BAR) at zero flow
120 - 125 psi (8.2 - 8.5 BAR) at 0.6 gpm (2.6 lpm)
9. Coolant Flow Rate
0.5 gpm (2.2 lpm) with 150 feet of total torch and torch
leads at 70°F (21°C)
NOTE
The flow rate varies with lead length, torch con-
figuration, ambient temperature, amperage level,
etc.
10. Cooling Capacity
4,000 to 10,000 BTU
NOTE
Maximum value based on "free flow" condition.
11. Coolant Reservoir Capacity
2 gallons
Capable of handling a total of 150 feet of torch lead
length
12. Secondary Water
Tap water can be used as a secondary gas and must
be capable of delivering the following minimums:
• Water pressure of 50 psi (3.5 BAR)
• Flow of 8 gph (35.2 lph)
NOTES
Tap water should only be used as a secondary gas
on machine torches.
The tap water source does not need to be deionized,
but in water systems with extremely high mineral
content a water softener is recommended.
