10 TROUBLE SHOOTING CHART
Problem Likely Reason Outcome
All Transformer 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.
Mains Circuit breaker
nuisance tripping during
welding.
Mains Circuit breaker
inadequately rated, or duty
cycle exceeded.
The circuit breaker may be
rated for Ieff (effective current).
If Weld output is greater
than the 100% rating the
machine will require mains
current higher than Ieff
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,
but 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.
Generator cannot provide
high peak cycle currents for
inverter
Extension leads creating
additional resistance, and
voltage drop
Use larger kVA generator or
sometimes a different band
generator will work.
Use larger cable size, and
keep extension lead as
short as possible.
