9 - MAINTENANCE

Twice a year, depending on the use of the device, inspect the following:
cleanliness of the power source
■
electrical and gas connections
■
WARNING
NEVER CARRY OUT CLEANING OR REPAIR WORK INSIDE THE
DEVICE BEFORE MAKING SURE THAT THE UNIT HAS BEEN
COMPLETELY DISCONNECTED FROM THE MAINS.
DISMANTLE THE GENERATOR PANELS AND USE SUCTION
TO REMOVE DUST AND METAL PARTICLES ACCUMULATED
BETWEEN THE MAGNETIC CIRCUITS AND THE WINDINGS OF THE
TRANSFORMER.
WORK MUST BE PERFORMED USING A PLASTIC TIP TO AVOID
DAMAGE TO THE INSULTATION OF THE WINDINGS.
WARNING
THE CLOGGING OF THE DUST FILTER MAY LEAD TO THE
DECREASE OF THE DUTY CYCLE OF THE GENERATOR.
WARNING : TWICE A YEAR
COMPRESSED AIR BLOWING.
■
PERFORM CALIBRATION OF THE CURRENT AND VOLTAGE
■
SETTINGS.
CHECK ELECTRICAL CONNECTIONS OF THE POWER,
■
CONTROL AND POWER SUPPLY CIRCUITS.
CHECK THE CONDITION OF INSULATION, CABLES,
■
CONNECTIONS AND PIPES.
WARNING :
AT EACH START-UP OF THE WELDING UNIT AND PRIOR TO
CALLING CUSTOMER SUPPORT FOR TECHNICAL SERVICING,
PLEASE CHECK THAT:
POWER TERMINALS ARE NOT IMPROPERLY TIGHTENED.
■
THE SELECTED MAINS VOLTAGE IS CORRECT.
■
THERE IS PROPER GAS FLOW.
■
TORCH CONDITION.
■
TYPE AND DIAMETER OF THE WIRE.

9.1 - ROLLERS AND WIRE GUIDE

Under normal conditions of use, these accessories have a long serviceable
life before their replacement becomes necessary.
Sometimes, however, after being used over a period of time, excessive
wear or clogging due to adhering deposits may be noted.
To minimize such harmful effects, make sure the wire feeder plate remains
clean.
The motor reduction unit requires no maintenance.

9.2 - TORCH

Regularly check the proper tightness of the connections of the welding
current supply. Mechanical stresses related to thermal shocks tend to
loosen some parts of the torch, particularly:
The contact tube
■
The coaxial cable
■
The welding nozzle
■
The quick connector
■
Check that the gasket of the gas inlet tip is in good condition.
Remove the spatter between the contact tube and the nozzle and between
the nozzle and the skirt.
Spatter is easier to remove if the procedure is repeated at short intervals.
Do not use hard tools that may scratch the surface of these parts and
cause spatter to become attached to it.

■
Blow out the liner after each change of a spool of wire. Carry out this
procedure from the side of the quick fitting connector plug of the torch.
If necessary, replace the wire inlet guide of the torch.
Severe wear of the wire guide may cause gas leaks towards the rear of
the torch.
The contact tubes are designed for long use. Nevertheless, the passage of
wire causes them to wear off, widening the bore more than the permissible
tolerances for good contact between the tube and the wire.
The need to replace them becomes clear when the metal transfer process
becomes unstable, all the settings of the work parameters remaining
otherwise normal.
