POWER SOURCE ERROR CODES

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 E11 error code displayed
Over Primary supply
(input) voltage at primary
capacitors is exceeded
for one second.
5 E14 error code displayed
Under mains supply
(input) voltage warning
primary capacitors is
reduced for one second.
6 E12 error code displayed
Under mains supply
(input) voltage primary
capacitors is reduced for
one second.
7 E81 error code displayed
Wrong Primary supply
(input) voltage
connected.
8 E82 error code displayed
Link switch plug not
connected.
Power Source Error Codes
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 voltag.
Primary supply voltage is
greater than the nominal
voltage plus 10%.
Mains supply voltage is less
than the nominal operating
voltage less 10%.
Mains supply voltage is
down to a dangerously low
level.
When 3 phase machine is
first turned on with the wrong
Primary supply (input)
voltage connected.
Link switch plug not
connected.
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.
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 or a
qualified electrician check
the Primary voltage.
Have an Accredited Thermal
Arc Service Agent or a
qualified electrician check
the Mains voltage.
Have an Accredited Thermal
Arc Service Agent or a
qualified electrician check
the Mains voltage.
Have an Accredited Thermal
Arc Service Agent or a
qualified electrician check
the Mains voltage.
Have an Accredited Thermal
Arc Service Agent check
connector plug on input PCB.
