Mains power supply

Rating plate with supply connection data
Check that the unit is connected to the correct mains power supply
voltage, and that it is protected by the correct fuse sizes. A protective
earth connection must be made, in accordance with regulations.

Note! Data in brackets (xxxx) are valid for power sources without primary inductor.
Note! 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 the
cable area and fuse sizes comply with the relevant national regulations.

Terminating resistor, MIG machines

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.

Connection of multiple wire feed units, MIG machines

With control unit U8 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:
1 TIG--torch and 1 MIG--gun (Universal power source required)
S
2 MIG/MAG--guns
