10 TROUBLE SHOOTING CHART
Problem
Likely Reason
Outcome
All Inverter Multi-Process Models
No welding current, no
display.
The machine is not turned on
at both the mains supply and
the machine power switch.
If confirmed that the machine
is switched on correctly,
test the same outlet using a
known serviceable appliance.
Circuit breaker nuisance
tripping during welding.
Circuit breaker inadequately
rated, or duty cycle exceeded.
The circuit breaker may
be rated for Ieff (effective
current). Welding machines
can draw considerable
amounts more than the
effective current at maximum.
The duty cycle should be
observed and understood.
Machine continually cuts
out on thermal overload
The machine duty cycle has
been exceeded.
Leave the machine
energized, with the fan
running until the machine
has cooled sufficiently.
The duty cycle should be
observed and understood.
No welding current,
display on.
The connections may not be
made securely.
Ensure all connections are in
position and securely made.
Machine gives poor
quality weld.
The polarity of the electrode/
return cables is incorrect.
The return lead contacts, or
workbench surface requires
cleaning.
Polarity should be confirmed
for the process/wire type in
use.
The return lead contacts
and connections should be
inspected and cleaned, and
the workbench cleared of
waste materials.
Machine works fine on
mains power but does not
work when connected to
a generator.
Machine works fine on
mains power but does not
work when connected
with extension lead.
Incompatibility of the
welding machine and the
generator.
Extension leads in use
creating additional
resistance.
Generators and inverter
welding machines can have
compatibility issues due to
the run up/down cycles of
generators.
The extension leads may also
contribute to considerable
volts drop, making the welder
inoperative.
