4.2 Function explanations for settings
Voltage
Higher voltage increases the arc length and produces a hotter, wider weld pool.
The voltage setting differs between synergy and non synergy modes. In synergy
mode, the voltage is set as a positive or negative offset from the synergic line of the
voltage. In non synergy mode, the voltage value is set as an absolute value.
The voltage is set in the measure, weld data setting ,or fast mode menus. When the
remote control unit is used, the setting can be adjusted from here.
Wire feed speed
This sets the required feed speed of the filler wire in m/minute.
The wire feed speed is set in the measure, weld data setting ,or fast mode menus.
When the remote control unit is used, the setting can be adjusted from here.
Inductance
Higher inductance results in a wider weld pool and less spatter. Lower inductance
produces a harsher sound but a stable, concentrated arc.
Inductance is set in the weld data setting menu.
Only applies to MIG/MAG welding with short--/sprayarc.
Regulator type
Affects the short circuit process and heat in the weld.
The setting should not be altered.

Pulse current
The higher of the two current values in the event of pulsed current.
Pulse current is set in the weld data setting menu with the synergy function switched
off.
Only applies to MIG/MAG welding with pulsing.
Pulse time
The time the pulse current is on during a pulse period.
Pulse current is set in the weld data setting menu with the synergy function switched
off.
Only applies to MIG/MAG welding with pulsing.
Pulse frequency
Time for background current which, along with the time for pulse current, gives the
pulse period.
Pulse frequency is set in the weld data setting menu with the synergy function
switched off.
Only applies to MIG/MAG welding with pulsing.
Background current
The lower of the two current values in the event of pulsed current.
Background current is set in the weld data setting menu with the synergy function
switched off. Only applies to MIG/MAG welding with pulsing.

Slope
“Slope” means that the pulse current slowly increases/decreases to the set value.
The “Slope” parameter can be set in nine stages, with each stage corresponding to
100 μs.
The slope is important as regards the sound. A steep slope produces a louder and
sharper sound. Too gentle a slope can, in the worst case scenario, impair the pulse’s
ability to cut off the droplet.
