lecting and pressing Short or Pulsed for at least 2 seconds.
Short
indicates that the short synergic welding mode is
selected.
Pulsed indicates that the pulsed synergic welding mode
is selected.
• Welding mode (Start Mode).
To choose the welding start mode 2T, 4T or 3L, select
one of the 2 modes by means of the knob B and
press the knob B for less than 2 seconds to confirm
the choice. This operation always returns us to the

Mode 3L Specially well suited to weld aluminium.
3 currents are available that can be used in welding by
means of the weling torch start button. The current and
the slope time values are set as follows:
Start Curr, starting current, adjustable from 10 to
200% of set welding current.
Slope time, possibility of adjusting from 0.1 to 10
seconds. Defines the connection time between starting
current (Start Curr) and welding current and between
welding current and crater filler current or crater filling
at the welding end (Crater Curr).Possibility of adjusting
from 10 to 200% of the set welding current.
Welding starts at the welding torch button pressure.
The named current will be the starting current Start
Curr. This current is kept as long as the welding torch
button is held down; when the welding torch button is
released the starting current connects to the welding
current, which is kept as long as the welding torch

• Spot and pause time (Spot).
If we select the spot ON time, the Spot Time function
appears on the display screen. If we select this, we
can adjust it from 0.3 to 25 seconds by means of
the adjustment bar. Besides this function, the display
screen also shows Pause Time. If we select this, by
means of the adjustment bar, we can regulate the
pause time between one welding point or section and
another. The pause time varies between 0 (OFF) and 5
seconds.
To access the Spot Time and Pause Time functions,
press the knob B for less than 2 seconds. Adjustment
is always made by means of the knob B. To confirm,
simply press it for less than 2 seconds. Once the
choice has been confirmed, return is always made to
the display page (PROCESS PARAMS).
• Inductance
Adjustment can vary from -9.9 to +9.9. Factory setting
is zero. If the figure is negative, the impedance drops
and the arc becomes harder, while if it increases, the
arc is softer.
To access this function, simply highlight it using the
knob B and press it for less than 2 seconds. The display
screen A shows the adjustment bar. The figure can be
changed and confirmed by pressing the knob B for less
than 2 seconds.
