3.2 WF115 XP front control panel
L1: comes on as soon as the power source is powered.
L2: indicates cut-in of any protection devices such as
the thermal protection.
L3: comes on when voltage is present at the welder out-
put.
D1, D2 7-segment display: permits dis-
play of general welder information
during start-up, the settings and current and voltage rea-
dings during welding, and alarm codes.
E1 encoder key: permits adjustment of the wire speed
in manual MIG
MIG
Gives access to set up, selection and setting of the parameters.
T1, synergy: permits selection of the manual MIG process
or synergic MIG setting the type of material to be welded.
Manual MIG process.
Synergic MIG process, carbon steel welding.
Synergic MIG process, stainless steel welding.
Synergic MIG process, aluminium welding.
T2, wire diameter: in synergy, permits selection of the diame-
ter of the wire used.
Diameter of wire used in mm
T3: used to select 2-stage, and 4-stage welding, it causes wire-
feeding when operating cover is open.
Two-Stage: in two-stage mode, pressing the button
causes the gas to flow, activates the voltage on the wire
and moves it forward; when released, the gas, the voltage and
the wire feed are de-activated.
Four-Stage: in four-stage mode, the first time the but-
ton is pressed, the gas flows, running a manual pre-gas
time; when released, the wire voltage and feed are activated. If
the button is pressed again, the wire is blocked and the final
process is initiated, setting the current to zero; final release of
the button stops the gas flow.

Wire feeder: permits manual wire feed, a function that
is enabled with the coil compartment gate open (for
the passage of the wire along the torch sheath during prepara-
tion operations). When the gate is open, the torch button ena-
bles only the flow of gas.
3.2.1 Set up
Permits set up and adjustment of a series of additional parame-
ters for improved more accurate control of the welding system.
The parameters present at set up are organised in relation to the
welding process selected and have a numerical code.
Entry to set up: by pressing the encoder key for 3 sec. (the cen-
tral zero on the 7-segment display confirms entry).
Selection and adjustment of the required parameter: by turning
the encoder until displaying the numerical code relating to that
parameter. If the encoder key is pressed at this point, the value set
for the parameter selected can be displayed and adjusted.
Exit from set up: to quit the "adjustment" section, press the
encoder again.
To exit the set up, go to parameter "O" (save and quit) and press
the encoder.
List of set up parameters
0 Save and quit: allows you to save the changes and quit the
set up.
1 Reset: allows you to reset all the parameters to the default
values.
3 Pre-gas: allows you to set and adjust the gas flow prior to
sparking of the arc.
Permits filling of the torch with gas and preparation of the
environment for welding.
Minimum off, Max 25 sec., Default 0.01 sec.
4 Soft start: permits adjustment of the wire feed speed in the
phases prior to sparking.
Given as a % of the wire speed set.
Permits sparking at reduced speed, therefore softer and
with fewer splashes.
Minimum 10%, Max 100%, Default 50%
5 Motor ramp: allows you to set a gradual transition between
the sparking wire speed and the welding wire speed.
Minimum off, Max 1.0 sec., Default off
18 Burn back: permits adjustment of the wire burn time, pre-
venting sticking at the end of welding.
Permits adjustment of the length.
Permits adjustment of the length of the piece of wire outsi-
de the torch.
Minimum 0.01 sec., Max 2 sec., Default 0.02 sec.
20 Post-gas: permits setting and adjustment of the gas flow at
the end of welding.
Minimum off, Max 10 sec., Default off
25 Spot welding: allows you to enable the "spot welding" pro-
cess and establish the welding time.
Minimum off, Max 25, Default off
26 Pause point: allows you to enable the "pause point" process
and establish the pause time between one welding opera-
tion and another.
Minimum off, Max 25, Default off
3.2.2 Alarm codes
01/02 Overtemperature.
05 Secondary short circuit.
08 Wire feed motor blocked.
11 Machine configuration not valid.
14 Welding not possible with the step set.
20 Communication error.
21 Machine not calibrated or loss of data.
