Arc length: Used to vary the basic voltage
used for welding.
Deposit: Used to modify the deposit of filler
material (wire speed) compared to the pre-
determined synergic value.
Double pulse: Used to activate (ON) or
deactivate (OFF) the mode at two levels, in
other words the continual switching between
two different welding current levels.
L1 span: When the two level mode is active
this function is used to set the duration of the
first current level.
L2 span: When the two level mode is active
this function is used to set the duration of the
first current level.
L2 amplitude: When the two level mode is
active this function is used to set the second
level current (L2) compared to the current
set (L2l)
L2 arc length: When the two level mode is
active this function is used to modify the arc
length of the second level (L2) independently
of the arc length of level L1 (arc length
parameter)
2s: In 2 time operating mode the machine
welds for the entire time the torch button is
held down.
4s In 4 time operating mode pressing the
torch button once starts the weld and press-
ing it a second time ends the weld.
4bi: This operation is similar to the 4t mode
with the only difference that pressing the
torch button for short periods (< 1s) during
welding causes the passage of the current
from the first level I1 to the second level I2;
holding the button down (> 1s) causes the
start of the end of the weld
2nd level: Used to set the value of the
current relative to the second power level,
active when the value of the 2t-4t-4bilevel
parameter is set to 4bi.
start/End level: Used to activate (ON) or
deactivate (OFF) the mode with the initial
and final current.
Start level: Used to set the initial value as a
percentage of the welding current (e.g. 130%
implies Is=1,30xI1).
Start level time: Used in 2t mode to set the
time the initial current ls is applied
Ls->L1 slope: Used to set the duration of
the current ramp from the initial level Is to the
welding current I1.
L1->Lf slope: Used to set the duration of the
current ramp from the welding current I1 to
the final level If.
End level: Used to set the final current as a
percentage of the welding current (e.g. 80%
implies If=0.80xI1).
End level time: Used in 2t mode to set the
time of application of the final current If.
Spot welding: Used to set (if other than 0)
the maximum duration of the weld.
Pause: Used to set (if other than 0) the dura-
tion of the pause between two successive
spot welds..
Pre gas time: Used to set the time for
delivery of gas before striking the electric arc.
Post gas time: Used to set the time of gas
delivery after the welding current has
stopped.
Burnback: Used to vary the burnback time
of the wire at the end of the weld.
Soft-start: Used to modify the speed at
which the wire approaches in order to obtain
a soft arc ignition; high values correspond to
low approach speeds.
Hot start: Used to set the ignition current in
order to obtain a soft ignition; generally used
together with the Soft-start parameter.
Inductance: Used to modify the speed of
variation of the welding current to obtain a
harder arc (low values) or softer arc (high
values).
Water pump: Used to switch on (ON) or
switch off (OFF) the water pump unit if pres-
ent.
