WELDER
DOES
NOT
FUNCTION
WHEN
SWITCHED ON
Tripped thermal protection device: Shut the
welder's switch to off and allow it to cool for at
least 20 minutes. Reduce duration or frequency
of welding periods to help reduce wear on the
welder. Refer to Duty Cycle section.
Faulty or improperly connected control Switch:
Have a technician check and secure/replace Con-
trol Switch.
Internal fuse blown: Have a qualified techni-
cian check/replace.
WEAK ARC STRENGTH
Incorrect line voltage: Check the line voltage
and, if insufficient, have a licensed electrician
remedy the situation.
WIRE FEEDS, BUT ARC DOES NOT IGNITE
Improper ground connection: Make certain
that the workpiece is contacted properly by the
Ground Clamp and that the workpiece is prop-
erly cleaned near the ground clamp and the
welding location.
Improperly sized or excessively worn contact
tip: Verify that Contact Tip is the proper size for
the welding wire used. Check that the hole in
the tip is not deformed or enlarged. Also, check
that the tip is not dirty; this would prevent a
good connection. If needed, replace Contact
Tip with proper size and type.
WIRE FEEDS, BUT SHIELDING GAS DOES NOT
FLOW
Empty Gas cylinder: Check gas cylinder.
Nozzle plugged: Clean nozzle.
If damaged,
replace.
Regulator or cylinder valve closed: Make sure
both valves are adjusted properly.

within Torch cable.
