Problem This may mean Cause Solution
Gas flows when the
system is powered ON.
The incoming gas
pressure is too high.
• The gas pressure from
the compressor or
cylinder may be too
high.
• The gas solenoid valve
may be faulty.
• Check the gas supply to
make sure that it does not
exceed 135 psi (9.3 bar).
If necessary, reduce the
pressure.
• Perform test 4 to verify
that the gas solenoid
valve is functioning
correctly.
When pulling the torch’s
trigger, gas flows from the
torch, but the torch does
not fire or fires only for a
short period of time.
The consumables, torch,
or torch lead are not
functioning correctly, the
gas pressure may be too
low, or there is a voltage
imbalance on the power
board.
• The consumables may
be worn or damaged.
• The torch or torch lead
may be damaged.
• The gas pressure is too
low or the gas supply is
restricted.
• The power board is
faulty.
• Inspect the consumables,
torch, and lead. Replace
any damaged parts.
• Verify that the gas supply
is providing at least 65 psi
(4.5 bar). Repair any
restrictions in the supply
line.
• Perform test 3 to test the
voltage balance on the
power board.
Arc goes out while
cutting or intermittently
will not fire.
The arc lost contact with
the workpiece.
• The work lead or work
lead connection may be
faulty.
• Check for loose
connections at the work
clamp and at the power
supply.
• Reposition the work lead
on the workpiece.
• Clean the cutting surface
to ensure a better
connection with the work
lead.
When pulling the torch’s
trigger, the pilot arc starts
but then extinguishes
before the normal
5-second time-out period.
The consumables, torch,
or torch lead are not
functioning correctly, the
gas pressure may be too
low, the air quality may
be poor, or there is a
voltage imbalance on
the power board.
• The consumables may
be worn or damaged.
• The torch or torch lead
may be damaged.
• The gas pressure is too
low or the gas supply is
restricted.
• The air filter element is
dirty.
• The power board is
faulty.
• Inspect the consumables,
torch, and lead. Replace
any damaged parts.
• Verify that the gas supply
is providing at least 65 psi
(4.5 bar). Repair any
restrictions in the supply
line.
• Perform test 3 to test the
voltage balance on the
power board.
