2D) SYN PULSE
TIG pulse welding with synergic setting of parameters.
WARNING: This can only be programmed when the TIG DC with
HF ignition or TIG DC with “Lift” type ignition weld-
ing processes are used.
Press the PULSE key (T5) until the requited pulsation
is active.
Press the WELDING PARAMETERS SELECTION Key
(T10) a number of times to set the following (in addi-
tion to the WELDING PARAMETERS defined as be-
ing “BASIC”):
L20 L21
L23
T10
L20 BASE CURRENT I
b
2200 AC/DC 3000 AC/DC
25 ÷ 220 A 25 ÷ 300 A
This function, which is good for less skilled operators, makes it
possible to change the pulsation parameter (Peak current I
p
) and
the other values for the corresponding pulsation parameters (Base
current
I
b
- Pulsation frequency
f
) vary automatically.
To exit the setting phase, hold the WELDING PARAMETERS SE-
LECTION key (T10) down for about 1 second .
3 - WELDING PARAMETERS with PULSE mode and
CYCLE welding mode active (CYCLE LED on)
When this welding mode is active it is possible to work at 2 differ-
ent pulse current levels (
I
1
and
I
2
). To do so you must also set (not
only pulse parameters I
b
, I
p
, and f ), but also the 2 nd level PEAK
current ( I
2p
). The other 2 nd level pulse parameters (BASIC CUR-
RENT I
2b
and FREQUENCY f ) are achieved synergically. The
FREQUENCY remains constant while the 2 nd level BASIC CUR-
RENT
I
2b
is proportional to the ratio between the 1 st level currents.
3A - SLOW PULSE + CYCLE
Press the PULSE key (T5) until the requited
pulsation is active (SLOW LED on).
Press the WELDING MODE SELECTION key
(T9) until the CYCLE welding mode is active
(CYCLE LED on).
Press the WELDING PARAMETERS SELEC-
TION Key (T10) a number of times to set the
following (in addition to the WELDING PARAM-
ETERS defined as being “BASIC”):
