Troubleshooting (continued)
Problem
No welder output when

indicator LED is
illuminated.
No welder output when
switched on and tripped
protection/alert indicator
is illuminated.
Frequent circuit breaker
trips.
Poor welds.
Possible Cause
Loose ground clamp connection.
No input power supply.
Tripped thermal protector by
overheating (tripped
protection/alert indicator turns
on).
Overheat caused by
environmental factor (high room
temperature or insufficient air
flow).
Incorrect input voltage to
welder.
Circuit breaker is insufficient for
the working current of the
welder.
Too much amperage is drawing
due to the use of overlarge
welding wire.
Improper current/voltage
setting.
Workpiece is not clean (such as
rusty, painted or greasy).
Poor ground clamp or
torch/electrode holder
connection.
Rusty or dirty welding wire.
Insufficient shielding gas at
welding area.
Check and make sure the ground clamp is well attached
to the workpiece.
Check and make sure welder is plugged in.
Verify outlet output power.
Check the circuit breaker to see whether it is tripped or
not. Reset if necessary.
Cool the welder for at least 10 minutes. The tripped
protection/alert indicator LED should turn off after welder
cools down.
Reduce the duration of the welding period, or duty cycle,
or duration of use.
Check whether the fan inside the welder is working
properly.
Relocate to a cool working environment.
Check whether there is obstruction blocking air flow in
the room. Clear the obstruction if needed.
Check the outlet voltage.
Make sure the circuit breaker fits the working current of
the welder.
Refer to a qualified electrician if you are unable to resolve.
Recommended welding wires are 0.030/0.035 in. flux core
welding wire.
Make sure the welding current/voltage matches the
recommended setting on chart.
Ensure workpiece is clean and dry.
Check and make sure ground clamp/workpiece have good
connection; torch/electrode holder and machine have
good connection.
Check your wire. Clean it or replace with a new wire
spool.
Check whether gas cylinder is empty or not.
Check gas regulator setting and make sure the settings
are correct.
Check whether the shielding gas is being blown away. If
yes, move to a shielded area.
