Connection of a gas cooled closed chamber welding head4. 4. 3.
Polysoude UHP heads belong to this group.
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. This terminal is not marked by a colour.
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. The cable end is marked red.
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 torch shielding gas
The connection is made with a quick push-pull coupling on the connector panel (symbol
).
Connection of a shunt to the cooling fault detection circuit
On power sources before v.2.5.0 version, it is necessary to shunt the cooling circuit to prevent a coolant fault
detection.
