Control Unit; Digital-Display - Migatronic CWF Multi PI 320 Betriebsanleitung

The CWF Multi unit can be used together with a PI
320/350/400/500 or a PI PLASMA in robot installations
and other cases, where cold wire feeder units are
required.
More than one unit can be connected to PI but only
one can be active at a time.
The CWF Multi communicates with the PI via a CAN-
interface and is connected on the rear panel of the PI
via a cable, which can be up to 15 meters.
Before use the CWF unit must be dedicated a
unique ID no. (please read menu for special
settings). Simultaneously, the PI machine must be
set up to have an active CWF unit (please read the
PI instruction manual.

Selection of parameters
A parameter can be selected by means of the relative
keypad in the relevant section. A bright indication light
indicates the parameter selected.
Wire feed speed
Variable 0.20-5m/min.
Setting of the wire feed speed.
Storage of parameters - programs
This function enables storage of 20 different
programs (often used wire settings) and shift
from one complete program to another for changing
values. By pressing the keypad the display shows a
"P" and a number: "1", "2" etc. Each number includes
a program with all parameters and functions of the
CWF. To access the program the CWF must be
disabled to "OFF"-mode.
During normal use, programs for CWF are selected
directly from the control panel in the PI. It is therefore
possible to have several different CWF programs
synchronised with different welding programs of PI.
At the beginning of welding, the PI will inform the
specific CWF unit what will be the program to be used.
(CWF must be set to "ON-mode")
Reset of welding programs
The CWF needs to be disabled to "OFF"-mode. When
the requested program has been selected, the
pad should be kept pressed until the program number
flashes on and off. The keypad can then be released
again. All parameters of selected program have been
set to factory settings.
Wire inching backwards
The function is used for wire inching
backwards. The selected inching speed is
the same for all programs. Variable 0.2-5 m/min.
Wire inching forwards
The function is used for wire inching
forwards. The selected inching speed is the
same for all programs. Variable 0.2-5 m/min.
Wire feed proces during TIG welding
The keypad should be pressed until the
requested parameter is switched on in the
table.
Start delay
After arc ignition the start of the wire can be
delayed to permit the creation of a suitable
welding pool. Variable 0-10 sec.
