NB:
The mains cable areas and fuse sizes as shown above are in accordance with
Swedish regulations. They may not be applicable in other countries: make sure that

4.4 Terminating resistor
In order to avoid communication interference, the ends
of the CAN bus must be fitted with 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 be fitted with the terminating
resistor, as shown on the right.
4.5 Connection of multiple wire feed units
With control unit and wire feed units without control panel it is possible to manage up
to 4 wire feed units from one power source.
It is possible to choose between the following connections:
S
1 TIG-torch and 1 MIG-gun (Universal power source required)
S
2 MIG/MAG-guns
S
1 TIG-torch and 3 MIG/-guns (Universal power source required)
S
4 MIG/-guns
When welding with water-cooled MIG/-guns on all wire feed units, it is recommended
to connect a separate cooling unit for the 2 extra guns.
We recommend connecting the guns in parallel.
