Pulse Synergic Mig Welding - Fimer TM 355 EVO Manual De Instrucciones

Ls->l1 slope: Used to set the duration of the
current ramp from the initial level Is to the
welding current I1.
L1->le slope: Used to set the duration of the
current ramp from the welding current I1 to
the final level Ie.
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
duration of the
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.
Water pump: Used to switch on (ON) or
switch off (OFF) the water pump unit if
present.

4.3 Pulse synergic MIG WELDING

Pulse synergic MIG welding allows obtaining
a relatively cold welding bead and good
penetration.
The low energy input makes this welding
process particularly suitable for thin layers
and for materials such as stainless steel and
aluminium.
During welding with synergic adjustment, the
wire speed (i.e. welding power) can be
adjusted with knob 9 shown in Fig.1.

The other parameters are automatically
adjusted to the set power depending on the
type and diameter of the wire selected.
By turning switch 10 it is possible to choose
from the different MIG-MAG welding modes;
press the switch to select the desired option.
Once selected, the screen with the welding
wire material options will appear:
Settings that do not appear on the screen
are accessible by turning switch 10.
Once the type of wire has been selected
(using switch 10), the settings page for the
welding wire diameter will appear.
The wire's diameters could not be available
for all models.
