Welding GMAW, FCAW-GS and FCAW-SS Process in non-synergic mode
During non-synergic mode wire feed speed and welding
voltage or work (for the 40 program) are independent
parameters and must be set by the user.
Table 17. GMAW and FCAW non-synergic Welding
Programs
Process Program
GMAW, standard CV 5
GMAW, "POWER MODE" 40
FCAW-GS, standard CV 7 or 155
FCAW-SS, Standard CV 6
Note: The list of available programs depends on the
power source.
Procedure of begin welding of GMAW, FCAW-GS or
FCAW-SS process:

Connect Lincoln Electric power sources using
ArcLink
®
protocol to communication to wire feeder.

Place the machine conveniently near the work area
in a location to minimize exposure to weld spatter
and to avoid sharp bends in the gun cable.

Determine the wire polarity for the wire to be used.
Consult the wire data for this information.

Connect output the gun to GMAW, FCAW-GS or
FCAW-SS process to Euro Socket [1].

Connect the work lead to output sockets of the power
source and lock it.

Connect the work lead to the welding piece with the
work clamp.

Install the proper wire.

Install the proper drive roll.

Manually push the wire into the gun’s liner.

Make a sure, if it is needed (GMAW, FCAW-GS
process), that the gas shield has been connected.

Turn the input power ON.

Insert the wire into the welding gun.
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 [19] – GMAW
and FCAW-GS process.

Close the wire drive door.

Close the spool wire case.

Select the right welding program. Non-synergic
programs are described in the Table 17.
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 wire drive door 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.
For 5, 6 and 7 program can set:

Wire Feed Speed, WFS [9]

The welding voltage [10]

Burnback Time

Run-in WFS

Preflow Time/ Postflow Time

Spot Time

2-Step/4-Step

Crater

Wave Control

Pinch
For 40 program can set:

Wire Feed Speed, WFS [9]

Power in kW [10]

Burnback Time

Run-in WFS

Preflow Time/ Postflow Time

Spot Time

2-Step/4-Step

Crater

Wave Control

Pinch
The 2-Step - 4-Step changes the function of the gun’s
trigger.

2 Step trigger operation turns welding on and off in
direct response to the trigger. Welding process is
performed when the gun’s trigger is pulled.

4-Step mode allows to continue welding, when the
gun’s trigger is released. To stop welding, the gun’s
trigger is pulled again. 4-step mode facilitates to
making long welds.
Note: 4-Step does not work during Spot Welding.
