6.09 Power Source Error Codes
Description Possible Cause Remedy Remarks
1 E01 error code displayed
Temperature sensor TH1
(protects IGBTs) is
greater than 80ºC for
about 1 second.
A
B
C The Welding Power
Source’s duty cycle
has been exceeded.
Fan ceases to
operate.
Air flow is
restricted by vents
being blocked. A
B
C Let Power Source
cool down then keep
within its duty cycle.
Have an accredited
Cigweld Service
Provider investigate.
Unblock vents then
let Power Source
cool down. Weld current ceases.
Buzzer sounds
constantly.
Fan operates at max
speed.
E01 resets when TH1
decreases
to 70ºC for about 30
seconds.
2 E02 error code displayed
Temperature sensor TH2
(protects secondary
diodes) is greater than
80ºC for about 1 second.
A
B
C The Welding Power
Source’s duty cycle
has been exceeded.
Fan ceases to
operate.
Air flow is
restricted by vents
being blocked. A
B
C Let Power Source
cool down then keep
within its duty cycle.
Have an accredited
Cigweld Service
Provider investigate.
Unblock vents then
let Power Source
cool down. Weld current ceases.
Buzzer sounds
constantly.
Fan operates at max
speed.
E02 resets when TH1
decreases to 70ºC for
about 30 seconds.
3 E03 error code displayed
Primary (input) current
too high.
A
B Primary current is
too high because
welding arc is too
long.
Mains supply
voltage is
more than 10%
below
nominal voltage. A
B Reduce length of
welding arc.
Have an accredited
Cigweld Service
Provider or a
qualified electrician
check for low
Mains voltage. Weld current ceases.
Buzzer sounds
constantly.
Switch machine OFF then
ON to reset E03 error.
4 E04 error code displayed
Output voltage exceeds
the secondary voltage
specification.
TIG torch cable
and/or work lead
are too long or
leads are coiled.
Reduce the length of
the TIG torch cable
and/or work lead or
un-coiled leads.
Weld current ceases.
Buzzer sounds
constantly.
Switch machine off then
on to reset E04 error.
5 E11 error code displayed
Over Primary supply
(input) voltage at
primary capacitors is
exceeded for one
second.
Primary supply
voltage is greater
than the nominal
voltage plus 10%.
Have an accredited
Cigweld Service
Provider or a
qualified electrician
check the Primary
voltage.
Weld current ceases.
Buzzer sounds
constantly.
Error code E11
automatically will reset
when the voltage
reduces.
6 E12 error code displayed
Under mains supply
(input) voltage primary
capacitors is reduced for
one second.
Mains supply
voltage is down to
a dangerously low
level.
Have an accredited
Cigweld Service
Provideror a qualified
electrician check the
Mains voltage.
Weld current ceases.
Buzzer sounds
constantly.
Error code E12
automatically will reset
when the voltage
increases.
