Turning the screw M10 counterclockwise decreases the
spring tension and you can decrease the brake torque.
After finishing of adjustment, you should screw in the
fastening cap again.
Adjusting of Pressure Roll Force
WARNING
ELECTRIC SHOCK can kill.

Turn the input power OFF at the welding power
source before installation or changing drive rolls
and/or guides.

Do not touch electrically live parts.

When inching with the gun trigger, electrode and
drive mechanism are "hot" to work and ground and
could remain energized several seconds after the
gun trigger is released.

Do not operate with covers, panels or guards
removed or open.

Only qualified personnel
maintenance work.
Pressure force is adjusted by turning the adjustment nut
clockwise to increase force, counterclockwise to
decrease force.
The pressure arm controls the amount of force the drive
rolls exert on the wire. Proper adjustment of pressure
arm gives the best welding performance. Set the
pressure arm as follows:

Aluminum wires:

Cored wires:

Steel, Stainless wires:
WARNING
If the roll pressure is too low the roll will slide on the wire.
If the roll pressure is set too high the wire may be
deformed, which will cause feeding problems in the
welding gun. The pressure force should be set properly.
Decrease the pressure force slowly until the wire just
begins to slide on the drive roll and then increase the
force slightly by turning of the adjustment nut by one
turn.
Inserting Electrode Wire into Welding
Torch
Connect the proper welding torch to the Euro socket, the
rated parameters of the torch and of the welding source
shall match.
Remove the gas diffuser and contact tip from the
welding torch.
Switch the Cold Inch / Gas Purge switch [2] (see Figure
3.) in the position "Cold Inch" and keep in this position
until the electrode wire leaves the contact tip of the
welding torch.
Set the wire feeding speed in the position of about
10m/min by the Left Knob [2] (see Figure 1.).
WARNING
Take precaution to keep eyes and hands away from the
end of the torch while feeding wire.
English
should perform
between 1 and 3
between 3 and 4
between 4 and 6
4
WARNING
Once the wire has finished feeding through the welding
gun turn the machine "OFF" before replacing to contact
tip and gas diffuser.
Changing Driving Rolls
The machine is equipped with drive rolls for the wire of
1.0 and 1.2mm (factory default). For others wire sizes,
is available the proper drive rolls kit (see chapter
Accessories for ordering the desired kit). Below is the
drive rolls replacement procedure:

Switch off the machine.

Release the pressure roll lever [32].

Unscrew the fastening cap [33].

Open the protection cover [34].

Change the drive rolls [35] with the compatible ones
corresponding to the used wire.
For wires with the diameter greater than 1.6mm, the
following parts are to be changed:

The guide tube of the feeding console [36] and
[37].

The guide tube of the Euro socket [38].

Replace and tighten the protection cover [34] to the
drive rolls.

Screw the protection cover by fastening screws [33].
