PROBLEM
POSSIBLE CAUSE
POSSIBLE SOLUTION
Neither
INDICATOR
LED is
illuminated
and nothing
works on the
welder.
Machine is not turned ON.
Turn machine ON with
ON/OFF SWITCH
No input power present.
Make sure machine is
plugged in.
Verify that circuit breaker has
not been tripped.Reset if
needed.
Verify output power from the
outlet.
Do not use the machine on a
GFI outlet.
INDICATOR
LEDS are
illuminated and
there is no
output power
from the welder.
Exceeded duty cycle;thermal
protector
engaged.
Allow welder to cool at least
10 minutes with machine ON
(observe and maintain proper
duty cycle).FAULT/THERMAL
OVERLOAD INDICATOR
LED should turn off after the
machine has cooled
Insufficient air flow causing
machine to
overheat before reaching
duty cycle.
Check for obstructions
blocking air flow and ensure
that there are 12 inches of
clearance between any
obstacles and the vents on all
sides of the machine.
Incorrect voltage supplied to
welder.
Check the voltage of your
outlet. If it is 10% more or less
than 120V, call a qualified
electrician.
Low output or
non-penetrating
weld.
Too long or improper
extension cord.
Use a proper extension cord
(#12 AWG wire or heavier,no
longer than 25 ft.)
Poor ground connection or
torch/electrode
connection.
Reposition clamp and check
cable to clamp connection.
Check connection of ground
cable,torch or electrode
holder
Input power too low.
Have a qualified electrician
verify the voltage at your
outlet. If the voltage is
appropriate, verify that the
circuit wiring is sufficient for
40A.
