(ref.25 page 9) until the led A (ref.4 page 9) goes out. The A/wire speed encoder (ref.6 page
9) may be used to set the wire advance speed from 1.4 to 16 metres per minute, shown on
the left-hand display (ref.5 page 9). The optimised welding voltage will also be set
automatically.
6a) Regulating the wire speed from the wire feeder – The A/wire speed potentiometer
(ref.41 page 10) is used to regulate the wire speed following the scale indications or
checking its value on the left-hand display of the generator (ref.5 page 9). The optimised
welding voltage will also be set automatically.
7) Adjusting the welding voltage from the generator – Regulating the wire speed
automatically sets the optimised voltage for welding; if you want to correct the welding
voltage, it is sufficient to regulate the V/SET encoder (ref.8 page 9), obtaining a variation
from – 4V to +4V with respect to the original synergy value
To view the set adjustment value at any time, turn the V/SET encoder by one position.
7a) Adjusting the welding voltage from the wire feeder – The potentiometer V (ref.42 page
10) can be used to correct the welding voltage obtaining a variation from – 4V to +4V with
respect to the original synergy value. This may be obtained following the scale indications or
checking its value on the right-hand display of the generator (ref.7 page .).
As regards the regulations from the generator or from the wire feeder, the last regulations
made will remain operative also at the time of restarting the machine.
8) Exclusion of synergic mode – Press the SYNERGIC button (ref.26 page 9), this will
switch off the ON led (ref.27 page 9) .
DOUBLE PULSE FUNCTION
Regulation active only for the pulsed programs P
To make welds using the machine's double pulse function, the following settings must be
carried out:
1) Set the desired MIG mode and activate a pulsed synergic mode (see previous
paragraphs)
2) Inserting double pulse function DP – Press the DP button (ref.20 page 9), this will switch
ON the respective led (ref.18 page 9). The right-hand display will show the letters Std,
indicating that this is a pre-set standard regulation.
3) Changing the double pulse frequency – Press in sequence the DP button (ref.20 page 9),
the letters PFr will appear on the right-hand display. At this point, using the DP regulating
encoder (ref.19 page 9), it is possible to vary the frequency from 0.5 to 4 Hz. The ON led
