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

E02 resets when TH1
decreases 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.

5 E11 error code displayed

Over Primary supply
(input) voltage at primary
capacitors is exceeded for
one second.

Primary

supply

voltage is greater
than the nominal
voltage plus 10%.

Have an accredited

Thermal Arc Service
Agent or a qualified
electrician check the
Primary voltage.

Weld current ceases.
Buzzer sounds
constantly.
Error code E11
automatically will reset
when the voltage
reduces.
