Cast Iron electrode
Minimum
0/off
Welding current
7
Allows the regulation of the welding current.
Minimum
3 A
Arc force
8
Allows adjustment of the Arc force value in MMA.
Permits an adjustable energetic dynamic response in welding, facilitating the welder's operations.
Increase the value of the Arc force to reduce the risk of electrode sticking.

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.
Recommended for electrode: Basic, Rutile, Acid, Steel, Cast irons
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.
Recommended for electrode: Cellulosic, Aluminum
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
Recommended for electrode: Cellulosic, Aluminum
Arc detachment voltage
312
Allows you to set the voltage value at which the electric arc switch-off is forced.
In the spot welding phase, for example, a low arc detachment voltage reduces re-striking of the arc when moving the
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.
