3.3.1.6. "Inductance Corr" - Impedance value correction.

HD excepted)
Allows correction of the impedance value.

3.3.1.7. "Start Mode" -selecting the welding start mode.
2T (active in MIG/MAG and TIG processes).
The machine begins welding when the torch trigger is
pressed, and stops when released.
4T (active in MIG/MAG and TIG processes).
To begin welding press and release the torch trigger; to stop
welding press and release it again.
3L (active in synergic MIG/MAG processes).
Welding starts when the torch trigger is pressed; the welding
current set by means of "Start current" will be used. This
current will be kept as long as the torch trigger is held down;
when it is released the current returns to the preset value in
the time set as "Slope time" and it is kept until the torch
trigger is pressed again. When the torch trigger is pressed
again, the welding current will connect to the third current
("Crater-filler current") set with parameter "Crater Cur- rent"
according to the time set by "Slope time" and it will be
maintained until the torch trigger is released. When the torch
trigger is released welding stops.

according to "Slope Time".

3.3.1.13. "Double
processes and only in double pulsed machines).
This type of welding varies the intensity between two levels.
Before setting the double level welding, it is necessary to make
a short bead to determine the wire speed and the current to
obtain the penetration and the bead width closest to the type of
welding to be made.
The wire feed speed is thus determined (and the corresponding
current); the meters per minute that will be set will be
alternatively added to and subtracted from this value.
Before start working you should not forget that for a correct
bead, the minimum overlapping between two "meshes" must be
50%.

3.3.1.13.1. "Frequency" of double level.
The Hertz frequency is the number of periods per second.
Period means the speed alternating from the higher to the lower
values.
The lower value, that does not penetrate, is used by the operator
to change from one mesh to the next one; the higher speed,
corresponding to the maximum current, is the penetrating speed;
the operator will stop to make the mesh.
3.3.1.13.2
"Pulse Step": it is the amplitude of the
speed change in/min.
The speed change determines the sum and the the subtraction
of m/min from the reference speed described above. Parameters
being the same, when the number in- creases the mesh is wider
and penetration is deeper.
3.3.1.13.3
"Duty cycle": double level time.
Expressed as a percentage, this is the higher speed/current time
as compared to period duration.
