Parameter
Pinch – controls the arc characteristics during short-arc
welding. Increasing Pinch value results in a crisper arc
(more spatter) while decreasing provides a softer arc
(less spatter).

Regulation range: from -10.0 to +10.0.

Default value: 0.
Frequency - influences the width of the arc and the
amount of heat input to the weld.

Default value: 0.
Note: Adjust range depend on the power source.
Background Current - percentage value of nominal
welding current. Adjusts the overall heat input into the
weld. Changing the background current changes the
shape of the back bead.
Note: Adjust range depend on the power source.
UltimArc™ – for pulse welding programs adjusts the
focus or shape of the arc. In consequence of increasing
UltimArc™ value the arc is tight, stiff for high speed sheet
metal welding.

Adjust range: from -10 to +10.

Default value: 0.
ARC FORCE - the output current is temporarily
increased prevents the electrode from sticking and
facilitates the welding process.
Lower values will provided less short circuit current and a
softer arc. Higher settings will provided a higher short
circuit current, more forceful arc and possibly of more
spatter.

Default value: 0.

Regulation range: from -10.0 to +10.0
HOT START - percentage regulation of increasing
nominal current value during arc start with electrode. It
cause temporarily increased of output current and made
easy arc start with electrode.

Default value: +5.

Regulation range: from 0 to +10.0.
This parameter is for SMAW only.
Pulse Period - - influences the width of the arc and the
amount of heat input to the weld. If the value of
parameters is lower:

Improves penetration and the microstructure of the
weld.

The arc is narrower, more stable.

Reduces the amount of heat input to the weld.

Reduces distortions.

Increases welding speed.
Note: Adjust range depend on the power source.
