ADJUSTING THE WELDING VOLTAGE (ARC
LENGTH)
If the wire tends to disappear within the gas nozzle while you
would like to see its length, for instance to easily reach corners
or to direct it where you wish, then we need to shorten the arc
by setting it to a lower value of voltage, thus creating a greater
stick out.
With more wire out (stick out), you have a more concentrated
arc that generates a higher, more pronounced and a
slightly stretched out weld bead; if you wish to intervene,
it is necessary to increase the arc voltage value.
A higher arc voltage greater contributes to further spread
the weld bead material, keeping practically unchanged
the penetration that instead depends mainly on the value
of current, on the wire speed and on the inductance.
To change the welding
voltage V
,
simply press the
knob
B
for less than 2
seconds. The display screen
will show (
Arc Length
) an
adjustment bar with central
0. The value can be changed by means of the knob
B
from -9.9 to 9.9. To exit from the function, briefly press the
knob
B
.
By changing the value, once having exited the sub-menu,
alongside the voltage V, an arrow will appear turned
upwards to indicate a higher adjustment of the set value,
while the arrow turned downwards will indicate a lower
adjustment.
ADVANCED SETTING
•
Process
Use knob
B
to choose or confirm a welding mode by se
-
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
previous display page (
PROCESS PARAMS
).
Mode
2T
, the machine starts welding when the torch
button is pressed and stops when this is released.
Mode
4T
, to start welding, press and release the torch
button. To complete welding, press and release again.
Mode
3L
Specially well suited to weld aluminium.
3 currents are available that can be used in welding by
means of the welding 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 Cur
r) 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
button is held down. When the torch trigger is pressed
again, the welding current will connect to the crater-
filler current (
Crater- Curr
) and it will be maintained
until the torch button is released.
