9 - MAINTENANCE
9.1. ENTRETIEN
Twice a year, depending on the use of the device, inspect the following:
cleanliness of the generator
electrical and gas connections
9.2. 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.
9.3. 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.
The need to replace them becomes clear when the metal transfer process becomes unstable, all the settings of the work parameters remaining otherwise normal.
DIGIWAVE III
The clogging of the dust filter may lead to the decrease of the duty cycle of the generator.
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.
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.
Torch condition is very good.
Type and diameter of the wire.
