Welding GMAW and FCAW Process in
non-synergic mode
During non-synergic mode wire feed speed and welding
voltage are independent parameters and must be set by
the user.
Procedure of begin welding of GMAW or FCAW-SS
process:
Determine the wire polarity for the wire to be used.
Consult the wire data for this information.
Connect output the gas-cooled gun to GMAW / FCAW
process to Euro Socket [4].
Depending on the using wire, connect the work lead
[17] to output socket [2] or [3]. See [25] point –
terminal block of changing polarity.
Connect the work lead [17] to the welding piece with
the work clamp.
Install the proper wire.
Install the proper drive roll.
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.
Install a proper contact tip.
Depending on the welding process and the type of the
gun, install the nozzle (GMAW process) or protection
cap (FCAW process).
Close the Left side panel.
The welding machine is now ready to weld.
By applying the principle of occupational health and
safety at welding, welding can be begun.
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 [23].
Close the side panel.
Close the spool wire case.
Select the Right welding program.
Note: The list of available programs depends on the
power source.
Set the welding parameters.
The welding machine is now ready to weld.
WARNING
The side panel and wire spool case have to be completely
closed during welding.
WARNING
Keep the gun cable as straight as possible when welding
or loading electrode through cable.
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 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
