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.
Parameter set as a percentage (%) of the welding current.
Minimum Off, Maximum 500%, Default 30%
201 No-load voltage VRD
Minimum 12V, Maximum 73V, Default 73V
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
* Increasing the value of the arc force to reduce the risks
of sticking of the electrode.
205 MMA Synergy
Allows you to set the best arc dynamics, selecting the
type of electrode used:
1 Standard (Basic/Rutile)
2 Cellulose
3 Steel
4 Aluminium
5 Cast iron
Default standard (1)
Selecting the correct arc dynamics enables maximum
benefit to be derived from the power source to achieve
the best possible welding performances.
Perfect weldability of the electrode used is not guaran-
teed (weldability depends on the quality of the consum-
ables and their preservation, the operating and welding
conditions, the numerous possible applications, etc.).
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 operat-
ing 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.
24
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 57V
500 Allows access to the higher set-up levels:
USER: user
SERV: service
vaBW: vaBW
602 CH1 External parameter
Allows the management of external parameter 1 (mini-
mum value).
603 CH1 External parameter
Allows the management of external parameter 1 (maxi-
mum value).
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.
