3.2 Compressed air connection
Connection to a compressed air supply is necessary for operation of the
MULTISPOT M80 in conjunction with the spot welding tongs! The connection with
adjustable filter/pressure reducer (65) is located on the back of the power supply
unit (68). The operating pressure is 8 bar!
Insufficient pressure reduces the electrode contact pressure and increases
electrode wear. Excessive pressure can cause poor welding quality and
damage to the tongs.
When installing another air
connection, ensure that the thread of
the plug connector is screwed into the
filter pressure reducer no deeper than
8 mm, as otherwise the air supply will
be interrupted.
Seal the thread with Loctite.
