Connection and operation
Connection of welding hose
Plasma
Connection of electrode holder for MMA
The electrode holder and return current cable are connected to
plus tap (7) and minus tap (6). Observe the instructions from the
electrode supplier when selecting polarity.
Lift instructions
The lifting points must be used (please see
figure) when lifting the machine.
The machine must not be lifted with
mounted gas bottle.
Do not lift the machine by the handle.
Do not step on the handle.
CWF Multi (option)
It is possible to connect to the PI 350 PLASMA with up to 8 CWF
Multi units via dedicated CAN BUS connector placed on the rear
side of machine (option). In order to permit this control capability,
enter the USER Menu and select "Fdr" (feeder), then access "Act"
(Active devices) and set the parameter to 1. (see USER MENU)
Now the PI is ready to control the CWF directly from the box: for
each TIG welding program it is possible to select what CWF unit
must be activated and the relative CWF program in the range 1 to
20.
Depending from the settings on the CWF, if the unit is in OFF
mode the error message "Fdr" can be displayed on PI and the
welding process stopped. This is to inform the user the CWF is not
responding to start signal from PI.

Connection of remote control
PI PLASMA can be controlled via a remote control or
a welding robot. The remote control socket (14) has
terminals for the following functions:
A: Input signal for welding current,
0 – +10V input impedance:
1Mohm
B: Signal ground
C: Arc detect – contact of relay
(max. 1Amp), fully insulated
D: N.C.
E: Arc detect – contact of relay (max. 1Amp), fully
insulated
F: N.C.
G: Supply +24VDC. Short circuit protected with PTC
resistor (max. 50mA)
H: Supply ground
+15V
