SECTION 12:
POWER SOURCE ERROR CODES
Description
Possible Cause
Remedy
Remarks
A The Welding Power
Source’s duty cycle
has been exceeded.
A Let Power Source
cool down then
keep within its duty
cycle.
B Fan ceases to
operate.
B Have an Accredited
Thermal Arc Service
Agent investigate.
C Air flow is restricted
by vents being
blocked.
C Unblock vents then
let Power Source
cool down.
A The Welding Power
Source’s duty cycle
has been exceeded.
A Let Power Source
cool down then
keep within its duty
cycle.
B Fan ceases to
operate.
B Have an Accredited
Thermal Arc Service
Agent investigate
C Air flow is restricted
by vents being
blocked.
C Unblock vents then
let Power Source
cool down.
A Primary current is
too high because
welding arc is too
long.
A Reduce length of
welding arc.
B Mains supply
voltage is more than
10% below nominal
voltage .
B Have an Accredited
Thermal Arc Service
Agent or a qualified
electrician check for
low Mains voltage.
E04 error code
displayed
Output voltage
exceeds the
secondary voltage
specification.
1 E01 error code
displayed
Temperature sensor
TH1 (protects
IGBTs) is greater
than 80ºC for about
1 second.
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.
Weld current
ceases. Buzzer
sounds constantly.
Fan operates at max
speed.
E02 resets when
TH2 decreases to
70ºC for about 30
seconds.
3 E03 error code
displayed
Primary (input)
current too high.
Weld current
ceases. Buzzer
sounds constantly.
Fan operates at max
speed.
Switch machine off
then on to reset E03
error.
4
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.
