Note: The list of available programs depends on the power source.
In non-synergic mode wire feed speed and welding
voltage are independent parameters and must be set by
the user.
Procedure of beginning welding of GMAW, FCAW-GS or
FCAW-SS process:

Connect a recommended Lincoln Electric power
source (see ʺAccessoriesʺ chapter).

Place the welding set close to the work area, in the
place that minimize exposure to weld spatter and
guarantee avoid sharp bends of torch cable.

Determine the wire polarity for the wire to be used.
Check data sheet of wire to determine the wire
polarity.

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 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 [7] – 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 8.
Note: The list of available programs depends on the
power source.

Set the welding parameters.


The welding machine is now ready to weld.
The wire drive door and wire spool case have to be
completely closed during welding.
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 non-synergic mode you can set:

Wire Feed Speed, WFS

The welding voltage

Burnback Time

Run-in WFS

Preflow Time

Postflow Time

Spot Time

2-Step/4-Step

Crater

Polarity

Wave Control:

Pinch
Pinch controls the arc characteristics during short-arc
welding. Increasing Pinch Control results in a crisper arc
(more spatter) while decreasing provides a softer arc (less
spatter).

Adjust range: from -10 to +10.

Default value: 0.
