PROBLEM
POSSIBLE CAUSE
POSSIBLE SOLUTION
FAULT CODE F09 DISPLAYED.
Output short or abnormal voltage
feedback.
Make sure the MIG wire is not touching
the grounded work piece.
Make sure the TIG electrode is not
touching the grounded work piece.
Stick electrode stuck to work piece
Make sure that your stick electrode is not
stuck to the grounded work piece.
No 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.
Low output or non-penetrating
weld.
Weld parameters too low.
Adjust welding parameters
Too long or improper extension cord.
Use a proper extension cord (#12 AWG
wire or heavier, no longer than 25 ft.). See
“Extension Cords”, page 11.
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 the circuit breaker size.
Ground clamp, ground cable,
and/or welding cable get hot.
Bad ground or loose ground connection.
Check connection of ground cable, torch
or electrode holder.
Check connection of the ground cable
to the ground clamp. Tighten cable
connection to ground clamp if needed.
Ensure the connection between the ground
clamp and workpiece is good and on
clean, bare (not painted or rusted) metal.
Make sure cable is not damaged.
FREQUENT CIRCUIT BREAKER
TRIPS
Machine is drawing too much amperage
due to use of larger size electrode.
Use a smaller electrode.
Machine is not the only piece of electrical
equipment on the circuit.
Make sure the welder is on a dedicated
circuit or is the only thing plugged into a
circuit.
Circuit breaker is incorrect/insufficient for
use with this machine.
Verify that the circuit breaker for the circuit
is a 20A time-delay (slow-blow) breaker
for 120V and a 50A for 230V. If it is not,
have a qualified electrician install the
proper breakers.
