5 – MAINTENANCE

5.1 GENERAL

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 insulation of the windings.
At each start-up of the welding unit and prior to
calling customer support for technical servicing,
please check that:
● Power terminals are properly tightened.
● The selected mains voltage is correct.
● There is proper gas flow.
● Type and diameter of the wire.
● Torch condition.
TWICE PER YEAR
● Check electrical connections of the power,
control and power supply circuits.
● Check the condition of insulation, cables,
connections and pipes.
● Perform a compressed air cleaning.

5.2 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 minimise such harmful effects, make sure the wire feeder plate
remains clean.
The motor reduction unit requires no maintenance.

5.3 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 spigot 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.
● SPRAYMIG SIB, W000011093
● SPRAYMIG H20, W000010001
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.

5.4 COOLER PART

PREVENTIVE MAINTENANCE

Before use ensure to check the level of the liquid.
Clean the radiator of dust every six months. Once a year drain off the
Cooler II and refill with FREEZCOOL.
CAUTION
Never use the cooler without FREEZCOOL liquid.
Any use of a product different from FREEZCOOL
would invalidate the warranty. Water or any other
products is prohibited.
The FREEZCOOL must not be disposed of the
natural environment. You have must observe the
local country rules concerning the treatment and
the correct disposal of the cooling liquid. The safety
datasheets are available on the www.safetywelding.
com. The motor/pump requires no maintenance.
