8.02 Power Source Error Codes
Description Possible Cause Remedy Remarks
1. E01 error code displayed
Temperature sensor TH1
(protects IGBT) is too
hot. A.
The Welding Power 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.
When the detection temperature
of TH1 falls and the Control
Knob is pressed, E01 is reset.
B. Fan ceases to operate. B.
Have an Accredited SanRex
Service Agent investigate.
C. Air flow is restricted by
vents being blocked. C. Unblock vents then let Power
Source cool down.
2.
E02 error code displayed
Temperature sensor TH2
(protects secondary
diodes) is too hot.
A.
The Welding Power 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.
When the detection temperature
of TH2 falls and the Control
Knob is pressed, E02 is reset.
B. Fan ceases to operate. B.
Have an Accredited SanRex
Service Agent investigate.
C. Air flow 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. Primary current is too high
because welding arc is too
long A. Reduce length of welding
arc. Weld current ceases.
Buzzer sounds constantly.
Switch machine off, wait 3
seconds, and then switch on to
reset E03 error.
B. Mains supply voltage is more
than 10% below nominal
voltage. B. Have an Accredited SanRex
Service Agent or a qualified
electrician check for low
Mains voltage.
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.
Error code E04 resets when the
voltage reduces and the Control
Knob is pressed.
