SECTION 12:
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. E02 error code displayed
Temperature sensor TH2 (protects
secondary diodes) is greather than 80
o
C
for about 1 second
A. The Welding Powe Source’s duty
cycle has been exceeded.
A. Let Power Source cool down
then keep within its duty cycle.
Weld current ceases. Buzzer
sounds constantly.’Fan operates at
max speed.
E02 resets when the TH2 decreases
to 70
o
C for about 30 seconds
B. Fan ceases to operate. B. Have an accredited Thermal Arc
Service Agent investigate.
C. Air fl ow is restricted by vents being
blocked.
C. Unblock vents then let Power
Source cool down.
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 qualifi ed
electrician check for low Mains
voltage.
Weld current ceases.
Buzzer sounds constantly.
Switch machine off then on to reset
E03 error.
4. E94 error code displayed
Temperature sensor TH1 for IGBT’s or
sensor TH2 for secondary diodes are open
circuit.
The Welding Power Source’s
temperature sensors have
malfunctioned.
Have an Accredited Thermal
Arc Service Agent or a qualifi ed
electrician check or replace the
temperature sensors.
Weld current ceases.
Buzzer sounds constantly.
Switch machine off.
6. E99 error code displayed
Mains supply (input) voltage has been
turned off but control circuit has power
from the primary capacitors.
A. Main on/off switch on machine has
been turned off.
A. Turn on/off switch on. Weld current ceases.
Buzzer sounds constantly.
Must switch machine off and then
on to reset E99 error code.
B. Mains supply (input) voltage has
been turned off.
B. Have an accredited Thermal Arc
Agent or a qualifi ed electrician
check the Mains voltage and
fuses.
