Care and Cleaning
The stud welding system requires no special care.
See the operations manual specific to the units for the necessary cleaning work to the gun and if need be to
the feeder.
The cleaning work specified below is necessary for the Nelweld N550c unit. In this connection, pay attention to
the following:
Prior to commencing any cleaning work the welding unit must be switched off,
disconnected from the input power and secured against restart!

Perform preventive maintenance procedures at least once every six months. It is good practice to keep
a preventive maintenance record; a record tag attached to the machine works best.

Neither aggressive or alcoholic agents nor combustible liquids may be used for the cleaning work.

The unit casing of the N550c must be wiped down with a dry cloth. Type plate and safety advice must be
very legible.

The front plate of the N550c must be cleaned with a fat-dissolving cleansing agent. The LED display
elements must be recognizable.

The electrical connecting cables must be cleaned with a dry cloth. Scorching or mechanical faults can
thus be easily detected.

Cleaning inside the unit is required in keeping with the operating conditions and the degree of soiling.

Impurities inside the welding unit, such as metallic dust or conductive debris, must be wiped out or
vacuumed off
.
Opening the welding unit as well cleaning inside the unit may only be carried out
by an authorized electrical specialist!
Blowing down the welding unit with air pressure is not
recommended due to the risk of injury to lungs and eyes.
