Adjust the cut pressure
The compensator has a compensating valve that limits the maximum cutting water pressure, which is set at the factory
at 217 bar or 2,1 718 kPa (3,150 psi). This setting can be adjusted.

The differential pressure valve limits the minimum hydraulic pressure. The differential pressure valve is set at 21 bar
or 2,068 kPa (300 psi). If the differential pressure valve requires adjustment, contact Hypertherm Technical Service
for support.
Compensating valve
Required tools, materials, and parts
13 mm open-ended wrench (for a compensator with a cap)
17 mm open-ended wrench (for a compensator without a cap)
3 mm hex wrench
Do this with the pump running and the intensifier disabled. Refer to page 57 for instructions for disabling and enabling
the intensifier.
1. If the compensator has a cap, remove it.

The sealing washer under the cap might stick to the cap. The compensator will leak if the washer is not in position
when the cap is installed.
2. Use an open-ended wrench to loosen the jam nut 1 full turn (anticlockwise).
3. Use a 3 mm hex wrench to turn the adjustment screw to the right (clockwise) to increase pressure or to the left
(anticlockwise) to reduce the pressure.
4. Tighten the jam nut.
5. If the compensator has a cap, put it back on the compensator.
CAUTION
Do not adjust the hydraulic pressure higher than 217 bar or 21,718 kPa (3,150 psi). This can damage
the hydraulic and high-pressure systems.
