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 ʺAccessoriesʺchapter).
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 [12] – 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.
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.
For 6 and 7 program 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
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.

Note: The list of available programs depends on the power source.
In synergic mode, the welding voltage is not set directly
by user.The correct welding voltage will be set by the
machine’s software.
Optimal voltage value is related to the input data:
Wire Feed Speed, WFS.
If it is needed, the welding voltage can be adjusted by
the right control [23]. When the right control is rotated,
the display will show a positive or negative bar indication
if the voltage is above or below the optimal voltage.
Voltage setup above

Additionally can manually set:
Burnback
Run-In WFS
Preflow Time/ Postflow Time

Note: The list of available programs depends on the
power source.
Procedure of beginning welding of SMAW process:
Connect Lincoln Electric source to wire feeder
(mentioned in Introduction chapter).
Determine the electrode polarity for the electrode to
be used. Consult the electrode data for this
information.
Depending on the polarity of using electrode,
connect the work lead and the electrode holder with
lead to output sockets and lock them. See the Table

Install the proper electrode in the electrode holder.
Turn the input power ON.
Set the SMAW 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.
By applying the principle of occupational health and
safety at welding, welding can be begun.
For program number 1 can be set:
Welding current
Switch on / switch off the output voltage on the
output lead
Wave Controls:
ARC FORCE
HOT START
ARC FORCE - the output current is temporarily
increased prevents the electrode from sticking and
facilitates the welding process.
Lower values will provided less short circuit current and
a softer arc. Higher settings will provided a higher short
circuit current, more forceful arc and possibly of more
spatter.
Default value: 0.
Regulation range: from -10.0 to +10.0
HOT START – percentage regulation of increasing
nominal current value during arc start with electrode. It
cause temporarily increased of output current and made
easy arc start with electrode.
Default value: +5.
Regulation range: from 0 to +10.0.
