5 7-segment display
Allows the general welding machine parameters to be
displayed during start-up, settings, current and voltage
readings, while welding, and encoding of the alarms.
6 Main adjustment handle
Allows the welding (MMA) current to be continuously
adjusted.
Allows entry to set up, the selection and the setting of
the welding parameters.
Allows continuous adjustment of the wire feed speed.
Allows the regulation of the welding current.
Allows the thickness of the part being welded to be set.
Allows the setting of the system via the regulation of the
part being welded.
7 Main adjustment handle
Allows the regulation of the arc voltage.
Allows regulation of the arc length during welding.
High voltage = long arc
Low voltage = short arc
Manual MIG/MAG
Minimum 5V, Maximum 55.5V
Synergic MIG/MAG
Minimum -5.0, Maximum +5.0, Default syn
8 Welding process
Allows the selection of the welding procedure.
Electrode welding (MMA)
2 Step
In two step, pressing the button causes the gas to flow,
feeds voltage to the wire and makes it advance; when
it is released, the gas, the voltage and the wire feed are
turned off.
4 Step
In four step first pressure on the button causes the gas
to flow with a manual pre-gas time; releasing it activates
the voltage to the wire and its feed.
The following pressure on the button stops the wire and
causes the final process to start which brings the current back
to zero; finally releasing the button turns off the gas flow.

Crater filler
Allows welding to be done with three different power
levels able to be directly selected and controlled by the
welder using the torch button.
The first pressure on the button causes the gas to flow,
activates the voltage to the wire and feeds it at the
speed set by the "initial increment" parameter (during
set up) and with the relative synergic values of the weld-
ing parameters.
When the torch button is released, the wire speed and
the relative synergic parameters change automatically
to the main values set on the control panel.
The next pressure on the torch button brings the wire
speed and the relative synergic parameters to the pre-
set (during set up) crater filler parameter values.
Releasing the torch button stops the wire feed and sup-
plies the power for the burn back and post-gas stages.
11 Synergy (WF...Smart)
Allows selection of the manual MIG
process by setting the type of material to be welded.
Manual MIG/MAG process.
Synergic MIG/MAG process, welding of carbon steel.
Synergic MIG/MAG process, welding of stainless steel.
Synergic MIG/MAG process, welding of aluminium.
Synergic MIG/MAG process, welding of flux-core wire.
12 Wire diameter (WF...Smart)
In synergy, allows selection of the wire diameter used
(mm).
13 Synergy
Lets you select a preset welding program (synergy) by
choosing a few simple settings:
- wire type
- gas type
- wire diameter
