Connecting a “Polycar Hot Wire” type head4. 3. 4.
Connecting the electrode and hot wire current cables
Connect the current cable to the terminal marked “-” and the hot wire current cable to the “-” terminal circled
in purple on the connection panel using quick connectors which lock by turning clockwise.
Connecting earth cables
Connect the welding earth cable to the terminal marked “+” and the hot wire current earth cable to the “+”
terminal circled in purple on the connection panel. These terminals are surrounded by a red ring. Connec-
tion is made with a quick-fi t connector, locked by turning clockwise. Connect the other end of the cable to the
workpiece (Fig. 4.10), as close as possible to the joint to be welded, in an area free from grease and oxide.
Connecting the voltage measurement device to the workpiece
If servo control of height to the arc voltage is required, this voltage must be measured on the workpiece directly
and as close as possible to the electrode. A white wire, tied to the earth cable makes it possible to measure the
arc voltage on the workpiece. At the power source end, this wire is connected to the front connector panel FA
26 (symbol
U+
) with a screw connector.
Connection of the rotation motor cable
Connection is made on the connector panel at connector (symbol
). Make sure that the securing ring is
properly tightened, otherwise the system may not function correctly.
Connecting the arc height/oscillation motor cables
Connection is made on the connector panel at connector (symbol
).
Connecting the wire feeder motor cable
Connection is made on the connector panel using a screw connector (symbol
).
Make sure that the securing ring is properly tightened, otherwise the system may not function correctly.
