Troubleshooting (continued)
Problem
No welder output when
switched on and Tripped
protection/alert
indicator is illuminated.
Weak arc strength/non-
penetrating weld.
Frequent circuit breaker
trips.
Poor welds.
Dif ult to start an arc.
Possible Cause
□
Tripped thermal protector by
overheat (Tripped
protection/alert indicator turns
on).
□
Overheat caused by
environmental factor (high room
temperature or insuf
ow).
□ Incorrect input voltage to
welder.
□
Long or improper extension
cord.
□
Input power is too low.
□
Poor ground clamp, torch or
electrode holder connection.
□
Wrong size or worn contact tip.
□
Wrong welding wire size or type.
□
Circuit breaker is insuf
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.
□
Welding amperage is low.
□
Clogged contact tip.
□
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 ow in the
ent air
room. Clear the obstruction if needed.
□ Check the outlet voltage.
□
Use a proper extension cord.
□
Verify your welder's output voltage and current. Ask a
quali ed electrician for help if necessary.
□
Check connection of ground cable, torch or electrode holder
and make sure they are well connected.
□
Replace with the correct size contact tip or replace with a
new contact tip.
□
Recommended welding wires are 0.030/0.035 in. flux core
welding wire.
□
ent for Make sure the circuit breaker ts the working current of
the welder.
□
Refer to a quali ed electrician if you are not able to gure
out.
□
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.
□
Increase welding amperage.
□
Clean or replace contact tip.
