Welding GMAW and FCAW Process in
non-synergic mode
During non-synergic mode wire feed speed and welding
voltage are independent parameters that must be set by
the user.
Procedure of begin welding for GMAW or FCAW-SS
process:

First turn the machine off.

Connect by dedicated interconnection cable (see
„Accessories chapter"). wire feeder with a dedicated
welding power source that using the CAN protocol for
communication

Place the welding set near the work area to minimize
exposure to chipping and avoid sharp bend on the
welding cable.

Specify the polarity for the electrode wire that you
would like to use. See the specifications of the wire.

Connect GMAW or FCAW welding torch to the Euro
socket [1].

Connect work lead to proper output socket in power
source. For more information please refer to power
source instruction manual.

Connect the work lead to the welding piece with the
work clamp.

Install the proper wire.

Install the proper drive roll.

Insert the wire through the guide tube, over the rolls
and through the second guide tube of Euro Socket into
liner of gun. The wire can be pushed into the liner
manually for a few centimeters, and should feed easily
and without any force.

Make a sure if it is needed (GMAW process), that the
gas shield has been connected.

Turn the machine on.

Push the gun trigger to feed the wire through the gun
liner until the wire comes out of the threaded end.
WARNING
Keep the gun cable as straight as possible when loading
electrode through cable.
WARNING
Never use defected gun.

Check gas flow with Gas Purge Switch [14].

Close the wire drive door.

Close the spool wire case.

Select the right welding program.

Set the welding parameters.

The welding machine is now ready to weld.
WARNING
The wire drive door and wire spool case have to be
completely closed during welding.
WARNING
Do not kink or pull cable around sharp corners.

By applying the principle of occupational health and
safety at welding, welding can be begun.

Welding GMAW and FCAW Process in
synergic mode CV
In synergic mode, the welding voltage is not set by user.
The correct welding voltage will be set by the machine
software. Optimal voltage value depends of input data:

Wire Feed Speed, WFS.
If it is needed, the welding voltage can be adjusted by the
right knob [33]. When the right knob is rotated, the display
will show a positive or negative bar that indicates if the
voltage is above or below the optimal voltage.
Additionally user can manually set:

Burnback Time

Run-in WFS

Preflow Time

Postflow Time

Spot Welding Settings

2-Step/4-Step

