Polysoude PS 254 - Connection of an Air Cooled Closed Chamber Welding Head

16 MAN. PS 254 EN – Ind. 2
! Connection of the current return cable
Connect the current return conductor cable
onto the "+" terminal marked by a red ring.
Connection is made with a quick connector, by
a short 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 rotation motor cable
Join the cable on the "Rotation" connector
(symbol ). Make sure that the securing ring
is properly tightened, otherwise the system
may not function correctly.
! Connection of the torch shielding gas
hose
Connection is made with a quick push-type self
sealing coupling situated at the connection
plate of the power source (symbol ).
! Connection of the coolant circuit
Connection is made by 2 quick push type self
sealing couplings on the front view (symbols
and ).

! Connection of the electrode current
cable
Connect the current cable on the "-" terminal
with the quick connector, locking it by a short
rotation to the right. This cable is not indicated.
! Connection of the current return cable
Connect the current return conductor cable
onto the "+" terminal marked by a red ring.
Connection is made with a quick connector by
a short rotation to the right. This cable is
indicated red.
! Connection of the rotation motor cable
Connect the cable on the "Rotation" module
connector (symbol ). Make sure that the
securing ring is properly tightened, otherwise
the system may not function correctly
! Connection of the torch shielding gas
hose
Connection is made with a quickpush type self
sealing coupling disconnect fitting situated at
the bottom left hand corner of the front panel of
the PS 254 (symbol
").
! Connection of a bipass plug for the
coolant circuit security for use with air
cooled welding heads.
It is necessary to introduce the bipass plug to
isolate the cooling circuit security in order to
avoid a continuously detected fault.
