c e s s . N . B .
the box for
the process
in use is
highlighted
in green and
boxed in red.
The processes available are as follows:
MMA Welding with covered electrodes (see
chapter 13))

See chapter 16)
6 CHOICE OF TYPE OF ARC IGNITION (P SECTOR)
Select and
confirm P
sector for
arc ignition.
Select and
confirm type
of ignition.
N.B. the box
for the pro-
cess in use
is highlight-
ed in green.
By adopting this method, it is possible to select, modify
and confirm all the types of ignition presented below.
High frequency (HF) ignition, the arc ignites by
high frequency/voltage discharge.
Contact ignition, touch the workpiece with the
electrode tip, press the welding torch trigger and
raise the electrode tip.
EVO LIFT Touch the workpiece with the electrode
tip, press the welding torch trigger and raise the
electrode tip; as soon as the electrode is raised, a
high frequency/voltage discharge is generated which
lights the arc. Particularly suitable for precision spot
welding.
EVO START After the frequency/voltage dis-
charge, which lights the arc, the parameters are
set that favour joining of the edges of the material
to be welded during the first stage of welding.
The duration of the parameters mentioned above may be
adjusted from the main screen by selecting parameter
EVO ST . (see chapter 15).
After lighting the contact arc, the parameters are
set that favour joining of the edges of the material
to be welded during the first stage of welding.
The duration of the parameters mentioned above
may be adjusted from the main screen by selecting pa-
rameter
EVO ST (see chapter 15)
.
Touch the workpiece with the electrode tip, press
the welding torch trigger and raise the electrode
tip; As soon as the electrode is raised, a high fre-
quency/voltage discharge is generated which
lights the arc. Parameters are also set that favour joining
