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 TH2 ecreases
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.
