CEA MATRIX 4000 AC/DC - 3 WELDING PARAMETERS with PULSE Mode and CYCLE Welding Mode Active (CYCLE LED On)

12
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 welding process-
es are used.
Press the PULSE key (T5) until the requited pulsa-
tion is active.
SYN LED on.
Press the WELDING PARAMETERS SELECTION

“BASIC”):

This function, which is good for less skilled operators, makes it
possible to change the pulsation parameter (Peak current Ip ) and
the other values for the corresponding pulsation parameters (Base
current Ib - 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 ( I1 and I2 ). To do so you must also set (not
only pulse parameters Ib , Ip , 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 I2b is proportional to the ratio between the 1
st
level currents.
3A - SLOW PULSE + CYCLE (TIG AC-TIG DC)
Press the PULSE key (T5) until the re-
quited pulsation is active (the LED ON
SLOW flashing slowly).
Press the WELDING MODE SELEC-
TION key (T9) until the CYCLE weld-
ing mode is active (CYCLE LED on).
