DTX-2200-3000 AC/DC
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 SELECTION key (T10) down for about 1 second.
3. WEIDING PARAMETERS with PULSE mode and Bi-Level Welding mode active (Bi-Level LED on)
When this welding mode is active it is possible to work at 2 different 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 CURRENT I
2b
and FREQUENCY f ) are achieved synergically. The FREQUENCY
remains constant while the 2
nd
level BASIC CURRENT I
2b
is proportional to the ratio between the 1
st
level currents.

Press the PULSE key (T5) until the requited pulsation is active (SLOW LED on).
Press the WELDING MODE SELECTION key (T9) until the Bi- Level welding mode is active (Bi-Level LED on).
Press the WELDING PARAMETERS SELECTION key (T10) a number of times to set the following (in addition to
the WELDING PARAMETERS defined as being “BASIC”):
