Low water pressure
From the intensifier
It is normal for the pump pressure to fall when the cutting head is turned on. If the pressure falls lower than 276 bar or 27
579 kPa (4,000 psi), take these actions.
Make sure that the orifice is not defective.
Make sure that the intensifier does not stroke when it is in cut-pressure mode with the cutting head turned off. If it
does stroke, check the bleed-down valve and the high-pressure tubing for leaks.
If there are no leaks, make sure that the low-pressure and high-pressure poppets are in good condition.
Examine the check valves. Repair or replace them if necessary.
To the intensifier
A pressure switch downstream from the water filters senses water pressure to the intensifier. A sustained pressure lower
than 2.8 bar or 275 kPa (40 psi) causes the pump to turn off. This protects the system from running without enough
pressure to the intensifier.
The most common cause of this alarm is a lack of water to the pump. If this is suspected to be the cause of the alarm,
take these actions.
Make sure that the utility water to the pump is turned on.
Make sure that the water filters are not clogged.
Make sure that the water valve is not plugged.
Make sure that the cutting water solenoid fuse is not blown.
The fuse holder light comes on when a fuse blows.
Determine the cause of a blown fuse before replacing it. For fuse sizes and locations, refer to the technical drawings.
Some spare fuses are included with the controller. All fuses can be purchased from Hypertherm or an electrical supply
store.
If a fuse blows because of a damaged solenoid valve, replace the valve.
