This has different functions depending
on the selected procedure:

adjusts ”Arc Force” dynamic overcurrent (adjustment 0-100%) with a brief
indication on the display of the percentage increase in the value of the pre-
selected welding current. This adjustment is used to improve welding fluidity
and prevent the electrode from sticking to the piece being welded.
- TIG:
adjusts the welding current downslope (adjustment 0-100%) when the torch
button is released (SLOPE DOWN), with a brief indication on the display.
This adjustment is used to prevent the formation of craters at the end of
welding.
NOTE: ”POST-GAS” is adjusted automatically, using a time that is
proportional to the welding current setting.

10- Key for selecting welding parameters.
Pressing the key repeatedly will light up one of the LED's from (10a) to (10h)
associated with a specific parameter. The setting for each activated parameter is
made using the knob (13) and is shown on the display (15). While making these
settings knob (14) adjusts the value of the main welding level shown on the display
(16), either current or wire feed rate (see the explanation at point (14)).
Knob (14) will only allow adjustment of the secondary level if LED (10b) is ON (see
the description of LED (10b)).
Note: Parameters that cannot be modified by the operator, depending on whether
you are working with a synergy programme or in manual mode (“PRG 0”), are
automatically excluded from the selection; the corresponding LED will not light up.

5% to +5%) (LED (15c) ON).
Used to regulate the welding current (from 10A minimum to 350A maximum).
In the same mode, setting the bi-level function will cause the parameter to take the
value of arc length correction at the main welding level, calculated in synergy as
above (range from -5% to +5%) (LED (15c) ON).
Also in MIG/MAG Short arc mode, manual programming (“PRG 0”) is used to set
the actual arc voltage (range 10-40) (LED (15a) on)
In the same mode, setting the bi-level function will cause the parameter to take the
value of actual arc voltage at the main welding level (range 10-40) (LED (15a) ON).
10b-
Arc length (secondary level).
In MIG/MAG pulse arc mode, setting the bi-level, pulse-on-pulse or Tstart function
makes it possible to adjust current I2 (using knob (14)) and arc length correction
(using knob (13)) for the secondary welding level, calculated in synergy (range
from -5% to +5%) (LED (15c) ON).
In MIG/MAG short arc synergic programmes, setting the bi-level function makes it
possible to adjust wire feed rate (using knob (14)) and arc length correction (using
knob (13)) for the secondary welding level, calculated in synergy (range from -5%
to +5%) (LED (15c) ON).
If manual programming is selected (“PRG 0”) with the bi-level function it is possible
to adjust wire feed rate (using knob (14)) and actual arc voltage (using knob (13))
for the secondary welding level, (range 10-40) (LED (15a) ON).
10c-
MIG/MAG Pulse arc pinch-off, MIG/MAG short arc electronic
reactance or MMA Arc force.
In MIG/MAG pulse arc mode the parameter determines arc pinch-off. The higher
the value the more concentrated will be the arc during welding. In a welding mode
using two current levels (bi-level, pulse-on-pulse or Tstart) arc pinch-off has the
same setting for both levels.
In MIG/MAG manual mode (“PRG 0”) the parameter is used to adjust electronic
reactance (adjustment 20-80% and LED (15c) ON). A higher value will cause a
hotter weld pool. In bi-level mode electronic reactance has the same setting for
both levels.
In MMA electrode mode, the parameter takes on the meaning “Arc force” allowing
a dynamic overcurrent setting (0-100% adjustment and LED (15c) ON). During
MMA welding the display (15) shows the actual arc voltage (LED (15a) on), LED
(10c) also stays on to allow Arc force adjustment even during welding.

welding current time (regulation 0.1-10 seconds and LED (15b) ON).
In manual mode (“PRG 0”) it is used to adjust wire feed rate as welding starts so as
to optimise arc strike (1-100% adjustment and LED (15c) ON).
10e-
Secondary level time in MIG/MAG Pulse-on-Pulse mode or wire
burn-back when welding stops.
In MIG/MAG Pulse-on-pulse mode this parameter can be used to regulate
secondary welding current time (regulation 0.1-10 seconds and LED (15b) ON).
In MIG-MAG short arc manual mode (“PRG 0”) it takes the value of burn-back time.
That is, it is used to prevent the wire sticking to the piece when welding stops
(adjustment 0.01-1 seconds and LED (15b) ON).
10f-

arc Post-gas time.
In MIG-MAG Pulse arc 2-STROKE mode it is used to regulate start current time
(Tstart). If the parameter is set to zero the function is disabled, while with any other
setting greater than zero (adjustment 0.1-3 seconds) it is possible to select LED
(10b) to regulate the arc voltage correction and start current value (secondary
level). The start current can have either a higher or lower setting than the main
welding current; a higher start current is very useful especially when welding
aluminium and its alloys, and this actually makes it possible to heat the piece more
quickly (“Hot start”).
In any MIG-MAG Short arc mode the parameter corresponds to “Post-gas” time,
: MIG/MAG bi-level operation.
making it possible to adjust the time for which protective gas will flow after welding
stops (adjustment 0.1-10 seconds and LED (15c) ON).
