If both sides of the intensifier are stroking too fast, is a leak visible?
The intensifier does not stroke to either side
Yes The high-pressure tubing or a fitting is leaking. Identify the source of a leak and correct the
problem.
A high-pressure water seal is worn or damaged.
If the high-pressure seal is removed from
the plunger when you disassemble the
intensifier, replace the seal.
• Disassemble the intensifier.
• Examine the parts. Look for flaws,
deterioration, erosion marks, corrosion, or
cracks.
• Make sure that the mating surfaces are
smooth and clean.
• If damage is found, replace the component.
The bleed-down valve is leaking or has failed. Repair or replace the bleed-down valve.
The needle and the seat in the cutting head are
leaking.
• The on-off valve has failed.
• The cutting head has failed.
• Examine the parts. Look for flaws,
deterioration, erosion marks, corrosion, or
cracks.
• Make sure that the mating surfaces are
smooth and clean.
• If damage is found, replace the component.
No The orifice is worn, has failed, or is incorrectly
installed.
A worn or damaged orifice can increase the
demand for high-pressure water from the
intensifier. The orifice is the wrong size.
Replace the orifice.
The low-pressure water relief valve is venting
water to the drain. Remove the 3/8-inch tube from the valve at the
outlet fitting and monitor for leaks.
Cause Solution
Intensifier control is off.

Turn intensifier control on.
Refer to Intensifier Control on page 216.
The cutting head is off. Turn on the cutting head.
A proximity switch or the
proximity switch cord
has
failed.
Replace the component. Contact a Hypertherm

support.
An indicator spring is broken or damaged.
An indicator pin is stuck.
If the amber lights are on at the same time, a
proximity switch might have failed, an indicator
spring could be broken, or an indicator pin might
be stuck.
Examine all parts to find the cause of the fault.
