Check regularly that the wel ing power source is not clogge with irt.
How often an which cleaning metho s apply epen on: the wel ing process,
arc times, placement, an the surroun ing environment. It is normally
sufficient to blow own the power source with ry compresse air (re uce
pressure) once a year.
Clogge or blocke air inlets an outlets otherwise result in overheating.
B).Welding tor h
The wel ing torch's wear parts shoul be cleane an replace at regular

Check that the correct current value is
set.
Check
the
mains
power
supply.
The wel ing current is
interrupte uring wel ing.
Check to see whether the thermal
cut-outs have trippe .
Check
the
mains
power
supply
fuses.
The thermal cut-out trips
frequently.
Make sure that you are not excee ing
the rate ata for the
wel ing power source (i.e. that the
unit is not being
overloa e ).
Poor wel ing performance. Check that the wel ing current supply
an return cables are
correctly connecte .
Check that the correct current value is
set.
Check that the correct electro es are
being use .
Check the gas flow.
14) ERROR CODES :-

ERROR 001 :-
If
the
water
circulation
pump
is
off
or
the
water
is
not
passing through the torch then the Err 001 will be isplaye on the isplay.
B)
ERROR 002 :-
If

wel ing
machine
is
over
heate
then
the
Err
002
will be isplaye on the isplay.
15). DISMANTLING AND SCRAPPING
