The gas pressure is lower
than the minimum pressure
for the selected process,
operating mode, torch, lead
length, and Hypertherm
cartridge type.
The gas pressure is
inconsistent at your work site.
This fault code does not stop the system from
operating. Do the following.
• Examine all the connections for the input
gas supply. Make sure that there are no
leaks or loose connections.
• Make sure that the incoming gas supply
hose has an internal diameter of 10 mm
(3/8 inch) or greater if the hose is less than
15 m (50 feet). For hoses that are
15 m – 30 m (50 feet – 100 feet), use an
internal diameter of 13 mm (1/2 inch) or
greater.
• Make sure that there is sufficient inlet gas
pressure from the gas supply source.
• Manually adjust the gas pressure on the
plasma power supply.
• Do a gas test to see if the plasma power
supply’s actual output gas pressure is lower
than the set pressure by more than an
acceptable quantity. Refer to page 26.
• If there is no apparent problem with the inlet
gas supply, examine the air filter bowl and
air filter element in the plasma power supply.
Clean or replace as necessary.
• If the gas pressure or air compression is
inconsistent at the work site, and cut quality
and performance are satisfactory, you can
set the low gas pressure detection feature
to off. Use the UPL field on the Feature
Configuration screen. Refer to Default
feature configuration on page 153.
• With correct air connected to the plasma
power supply, do Test 10 – Solenoid valve
pressure sensor on page 115.
