Trouble Remedy
Arc goes out while cutting.
Be sure work clamp is securely attached to a clean, paint-free, rust-free workpiece.
Make sure drag shield is on the workpiece or the extended tip is 1/16 in. (1.6 mm) to 1/8 in. (3.2 mm) from
workpiece while cutting (see Section 5-4).
On thin metal, check travel speed. Constant travel speed must be maintained when cutting thin material.
Check that compressed air is clean, dry and oil-free. Use filter kit 300491 or 228926, if necessary.
Check retaining cup. DO NOT overtighen cup, hand-tighten only.
Clean or replace worn consumables as necessary (see Section 7-3).
Cup status light flashes steady for 15
seconds or until torch trigger is pressed,
whichever happens first.
System failed to strike an arc. Power source failed to deliver current to the output. Check continuity of
torch connections (pilot lead and electrode lead). If torch connections are good, have a Factory Autho-
rized Service Agent check unit.
Cup status light flashes at a rate of two
quick cycles and then a one second
pause for 15 seconds or until torch trig-
ger is pressed, whichever comes first.
No pilot arc established. The power source failed to maintain a pilot arc. Try a different set of torch con-
sumables (tip and electrode). Check for input pressure between 90-120 PSI.
Cup status light flashes at a rate of three
quick cycles and then a one second
pause for 15 seconds or until torch trig-
ger is pressed, whichever comes first.
Power source detected that tip and electrode failed to separate when gas valve turned on. Check that
cup is not too tight (finger tight only). Check for correct torch consumables. Check for gas flow through
the torch head.
Short tip life. Check and clean drag shield of any slag, particles, and debris.
Check position of cut/gouge switch. Place switch in correct position to match the process.
Check input air pressure.
Check that compressed air is clean, dry and oil-free. Use filter kit 300 491 or 228 926, if necessary.
Maintain 1/8 in (3.2 mm) standoff for extended tip cutting over 40 amps. Do not drag tip on workpiece.
If trouble persists, have system checked by a Factory Authorized Service Agent.
