SECTION 11:
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 fl ow 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.
E01 resets when TH1 decreases
to 70ºC for about 30 seconds.
2 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 qualifi ed
electrician check for low Mains
voltage.
Weld current ceases.
Buzzer sounds constantly.
Switch machine off then on to
reset E03 error.
3 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 qualifi ed
electrician check the Primary
voltage.
Weld current ceases.
Buzzer sounds constantly.
Error code E11 automatically will
reset when the voltage reduces.
4 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.
A
B
Have an Accredited Thermal
Arc Service Agent or a qualifi ed
electrician check the Mains
voltage.
Have an Accredited Thermal
Arc Service Agent or a qualifi ed
electrician check the primary
cable & fuses.
Weld current ceases.
Buzzer sounds constantly.
Error code E12 automatically
will reset when the voltage
increases.
5 E93 error code displayed
Memory chip (EEPROM) on control PCB
can not read/write weld parameters
Memory chip (EEPROM) error. Have an Accredited Thermal Arc
Service Agent check the control
PCB.
Weld current ceases.
Buzzer sounds constantly.
Switch machine off.
6 E94 error code displayed
Temperature sensor TH1 for IGBT’s is an
open circuit.
The Welding Power Source’s
temperature sensors have
malfunctioned.
Have an Accredited Thermal Arc
Service Agent check or replace
the temperature sensors.
Weld current ceases.
Buzzer sounds constantly.
Switch machine off.
