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 (MMA)
0 Save and quit
Allows you to save the changes and exit the set up.
1 Reset
Allows you to reset all the parameters to the default
values.
3 Hot start
Allows adjustment of the hot start value in MMA.
Permits an adjustable hot start in the arc striking phases,
facilitating the start operations.
Parameter set as a percentage (%) of the welding current.
Minimum Off, Maximum 500%, Default std 80%,
Default cls 150%
7 Welding current
Permits adjustment of the welding current.
Parameter set in Amps (A).
Minimum 3A, Maximum Imax, Default 100A
8 Arc force
Allows adjustment of the Arc force value in MMA.
Permits an adjustable energetic dynamic response in
welding, facilitating the welder's operations.
Increasing the value of the arc force to reduce the risks
of sticking of the electrode.
Parameter set as a percentage (%) of the welding current.
Minimum Off, Maximum 500%, Default std 30%,
Default cls 350%
204 Dynamic power control (DPC)
It enables the desired V/I characteristic to be selected.
I = C Constant current
The increase or reduction in arc length has no effect on
the welding current required.
Basic, Rutile, Acid, Steel, Cast iron
1÷ 20* Falling characteristic with adjustable slope
The increase in arc length causes a reduction in welding
current (and vice versa) according to the value imposed
by 1 to 20 amps per volt.
Cellulose, Aluminium
P = C* Constant power
The increase in arc length causes a reduction in the
welding current (and vice versa) according to the law:
V.I = K.
Cellulose, Aluminium
312 Arc detachment voltage
Allows you to set the voltage value at which the electric
arc switch-off is forced.
It permits improved management of the various oper-
ating conditions that occur. In the spot welding phase,
for example, a low arc detachment voltage reduces
re-striking of the arc when moving the electrode away
from the piece, reducing spatter, burning and oxidisa-
tion of the piece.
If using electrodes that require high voltages, you are
advised to set a high threshold to prevent arc extinction
during welding.
Never set an arc detachment voltage higher than
the no-load voltage of the power source.
Parameter set in Volts (V).
Minimum 0V, Maximum 99.9V, Default std 57V,
Default cls 70V
500 Allows the selection of the required graphic interface:
XE (Easy Mode)
XA (Advanced Mode)
XP (Professional Mode)
Allows access to the higher set-up levels:
USER: user
SERV: service
vaBW: vaBW
551 Lock/unlock
Allows the locking of the panel controls and the inser-
tion of a protection code (consult the "Lock/unlock"
section).
552 Buzzer tone
Permits adjustment of the buzzer tone.
Minimum Off, Maximum 10, Default 5
601 (U/D) Adjustment step
Permits adjustment of the variation step on the up-
down keys.
Minimum Off, Maximum MAX, Default 1
602 CH1, CH2, CH3, CH4 External parameter
Allows the management of external parameter 1, 2, 3, 4
(minimum value, maximum value, default value, param-
eter selected).
(Consult the "External controls management" section).
751 Current reading
Allow the real value of the welding current to be dis-
played.
752 Voltage reading
Allows the real value of the welding voltage to be dis-
played.
List of set up parameters (Standard MIG/MAG,
Pulsed MIG/MAG)
0 Save and quit
Allows you to save the changes and exit the set up.
1 Reset
Allows you to reset all the parameters to the default
values.
2 Synergy
Allows selection of the synergic MIG process by setting
the type of material to be welded.
(Consult the "Synergic curves screen" section).
