Troubleshooting (continued)
Problem
No welder output when
switched on and neither
indicator LED is
illuminated
No welder output when
switched on and tripped
protection/alert indicator
is illuminated.
Frequent circuit breaker
trips.
Poor welds.
Arc is wandering (TIG).
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.
□
Tungsten is too large.
□
Current is too low.
□
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.
□
Use a smaller tungsten.
□
Increase welding current.
