POWER SOURCE ERROR CODE

Description
1 E01 error code displayed
Temperature sensor TH1
(protects IGBTs) is
greater than 80°C for
about 1 second.
2 E02 error code displayed
Temperature sensor TH2
(protects secondary
diodes) is greater than
80°C for about 1 second.
3 E03 error code displayed
Primary (input) current too
high.
4 E94 error code displayed
Temperature sensor TH1
for IGBTs or sensor TH2
for secondary diodes are
open circuit.
5 E99 error code displayed
Mains supply (input)
voltage has been turned
off but control circuit has
power from the primary
capacitors.
POWER SOURCE ERROR CODE
Possible Cause
A The Welding Power
Source's duty cycle has
been exceeded.
B Fan ceases to operate.
C Air flow is restricted by
vents being blocked.
A The Welding Power
Source's duty cycle has
been exceeded.
B Fan ceases to operate.
C Air flow is restricted by
vents being blocked.
A Primary current is too
high because welding arc
is too long.
B Mains supply voltage is
more than 10% below
nominal voltage.
The Welding Power
Source's temperature
sensors have
malfunctioned.
A Main on/off switch on
machine has been turned
off.
B Mains supply (input)
voltage has been turned
off.

Remedy
A Let Power Source cool
down then keep within its
duty cycle.
B Have an Accredited
Thermal Arc Service Agent
investigate.
C Unblock vents then let
Power Source cool down.
A Let Power Source cool
down then keep within its
duty cycle.
B Have an Accredited
Thermal Arc Service Agent
investigate.tt
C Unblock vents then let
Power Source cool down.
A Reduce length of welding
arc.
B Have an Accredited
Thermal Arc Service Agent
or a qualified electrician
check for low Mains
voltage.
Have an Accredited
Thermal Arc Service Agent
check or replace the
temperature sensors.
A Turn on/off switch on.
B Have an Accredited
Thermal Arc Service Agent
or a qualified electrician
check the Mains voltage
and fuses.
