Definition
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-
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 only for SMAW.
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.
