Possible Cause
Unit is not plugged in
Input power circuit breaker not
on
The main power switch is not
working
Workpiece is painted or rusty
Ground clamp
where there is paint or rust
Ground clamp is not electrically
connected to the workpiece
Amperage too low for electrode
is The internal temperature is too
high.
The voltage of power supply is
lower or higher than required
range
Weld cable connections loose
Weld cable connections have
corroded.
Damp electrode
The electrode is kept in contact
with the workpiece for too long
while striking an arc
The welding travel speed is too
fast
The welding travel speed is too
slow
Plug in socket

This will take practice. Keep
trying.
Reduce the welding travel
speed. Maybe incorporate a
