32-92 PN-0509076 Rev. 16
Connection of an open welding head of the MU type or a tube/tubesheet welding head of the type 4. 4. 4.
TS or TP
Connection of the electrode current cable
Connect the current cable with the quick connector to the “-” terminal on the connector panel, locking it by
rotation to the right.
Connection of the earth cable
Connect the earth cable to the “+” terminal on the connector panel. The terminal is surrounded by a red ring.
The connection is made with a quick connector, locked by rotation to the right. Connect the other end of the
cable to the workpiece, as close as possible to the joint to be welded, in an area free from grease and oxide.
Connection of the AVC measurement plug to the workpiece
If servo control of height to the arc voltage is required, this voltage must be measured on the workpiece di-
rectly 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 con-
nector 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.
Connection of the AVC/oscillation motor cable
Connect the cable to socket (symbol ) on the front connection panel.
Connection of the torch shielding gas
The connection is made with a quick push-pull coupling on the connector panel (symbol
).
Connection of the cooling circuit
The connection is made with 2 quick couplings on the front connector panel (symbols
and ).
