L29 FREQUENCY of the AC welding current
The high frequency makes it possible to weld minor thicknesses
with excellent results, while the low frequency is ideal for welding
average thicknesses, or where edge preparation is poor.
WARNING: LED L29 switched on and flashing.
■ PULSE
When using one of the 3 TIG welding processes, it makes it pos-
sible to set one of the 4 pulsation modes available on the welding
machine, using the relevant button:
L25 SYN PULSE
L26 SLOW PULSE
L26 FAST PULSE
L26 ULTRA FAST PULSE
ON
FAST
ULTRA
FAST
SLOW
SYN
PULSE
L25 Synergic pulsations (SYN PULSE)
WARNING:
LED L25 switched on and steady.
This can only be programmed when the TIG DC with HF ignition
or TIG DC with “Lift” type ignition welding processes are used.
L26 Slow pulsations (SLOW PULSE)
WARNING:
LED L26 on and flashing slowly (hold the PULSATION button
down until the LED L26 flashes slowly).
This can only be programmed when the 3 TIG welding process-
es are used.
L26 Fast pulsations (FAST PULSE)
WARNING:
LED L26 on and flashing quickly (hold the PULSATION button
down until the LED L26 flashes quickly).
This can only be programmed when the TIG DC with HF ignition
or TIG DC with “Lift” type ignition welding processes are used.
L26 Ultra fast pulsations (ULTRA FAST PULSE)
WARNING:
LED L26 on and flashing very quickly (hold the PULSATION but-
ton down until the LED L26 flashes very quickly).
Attivabile solo con i processi di saldatura TIG DC con innesco HF
o TIG DC con innesco tipo “Lift”.
WARNING: The operator can decide to TIG weld without using
any pulsation mode. If this is the case, the 2 LEDs are switched off.
■ WELDING PARAMETERS
Each time the button is pushed, the welding machine selects the
next function according to the machine configuration, the welding
process, the welding mode, etc...
1A - STANDARD CONFIGURATION
Electrode welding (MMA)
When using the electrode welding process, this allows you to select
the following welding parameters, based on which LED is flashing:
