Terminating resistor

In order to avoid communication interference, the ends of the
CAN bus must have terminating resistors.
One end of the CAN bus is at the control panel, which has an
integral terminating resistor. The other end at the power
source must have a terminating resistor, as shown on the
right.

Connection of multiple wire feed units

With control unit and wire feed units without control panel (M0), you can manage up to 4 wire
feed units from one power source.
You can choose between the following connections:
• 1 GTAW (TIG) torch and 1 GMAW (MIG/MAG) gun (Universal power source required)
• 2 GMAW (MIG/MAG) guns
• 1 GTAW (TIG) torch and 3 GMAW (MIG/MAG) guns (Universal power source required)
• 4 GMAW (MIG/MAG) guns
When welding with water-cooled GMAW guns on all wire feed units, it is recommended to
connect a separate cooling unit for the two extra guns.
We recommend connecting the guns in parallel.

Check that the unit is connected to the correct main supply voltage,
and that it is protected by the correct fuse sizes. A protective ground
connection must be made, in accordance with regulations.
