12.0 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 Thermal
Arc Service Agent 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 Thermal
Arc Service Agent 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 Thermal
Arc Service Agent 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 Thermal
Arc Service Agent or a
qualified electrician check
the Primary voltage. Weld current ceases.
Buzzer sounds constantly.
Error code E11 automatically
will reset when the
voltage reduces.
