Arc-power
The arc power function is used to stabilise the
arc in MMA welding. This can be acheived by
increasing welding current during the short-circuits.
The additional current ceases when the short circuit is
no longer present.

Arc power can be adjusted between 0 and 100% of
the welding current setting.
E.g. If the welding current is set to 40A and arc
power to 50% the additional current is 20A
equals 60A when doing arc power. If the arc
power is set to 100% the additional current is
40A equals 80A when doing arc power.

Internal/external adjustment
It is possible to choose between internal and
external adjustment. The external adjustment is
active when the indicator is illuminated.
Anti-freeze
This machine is provided with an anti-freeze control.
The anti-freeze-control reduces the current when the
electrodes stick to the weld piece. This makes it easier
to break off the electrode and welding can continue.
