1.2
Normal Use
The automatic spray gun PILOT WA 650 is exclusively designed for use with spra-
yable material types and grades such as:
•
paints and lacquers
•
greases, oils and corrosion preventives
•
adhesive compounds
•
Separating agent
•
ceramic glazes
•
pickling solutions
To spray other materials please contact WALTHER Spritz- und Lackiersysteme
GmbH, Wuppertal.
Please note that sprayable material may only be applied to work pieces and/or simi-
lar items. The temperature of the sprayed material must generally not exceed 80°C.
The PILOT WA 650 model is no hand-guided spray gun and needs to be fastened
therefore with a suitable holder.
The term normal use also implies that any and all safety warnings, operational hand-
ling details, etc., as stated in these operating instructions, must be carefully read,
understood and duly complied with.
This equipment complies with the explosion protection requirements of Directive
2014/34/EU (ATEX) for the explosion group, equipment category and temperature
class indicated on the type plate.
When using the equipment, the requirements specified in these Operating Instructions
must be observed at all times.
The technical data indicated on the equipment rating
plates and the specifications in the chapter „Technical Data“ must be complied with
at all times and must not be exceeded. An overloading of the equipment must be
ruled out.
The equipment may be used in potentially explosive atmospheres only with the
authorisation of the relevant supervisory authority.
The relevant supervisory authority or the operator of the equipment are
responsible for determining the explosion hazard (zone classification).
The operator must check and ensure that all technical data and the marking of the
equipment in accordance with ATEX are compliant with the necessary requirements.
The operator must provide corresponding safety measures for all applications in
which the breakdown of the equipment might lead to danger to persons.
If any irregularities are observed while the equipment is in operation, the equipment
must be put out of operation immediately and WALTHER Spritz- und Lackiersysteme
GmbH must be consulted.
Grounding / Equipotential Bonding
You must ensure that the spray gun is properly earthed (grounded) either separately
or in connection with the equipment with which it is being used (maximum resistance
10

Technical Description
The PILOT WA 650 model works fully automatically via compressed air control and
is selected by a 3/2-way control valve provided by the customer.
The otherwise customary needle pack is replaced by a membrane with this model.
When the 3/2-way control valve is triggered, the compressed air required by the
control enters into the cylinder chamber of the spray gun and opens the atomizer air
channel and finally the material supply.
If the control air through the 3/2-way valve is interrupted again, the compressed air
remaining in the piston compartment will first escape. The spring pressure of the
piston spring subsequently pushes the material needle back to its original position,
closes the material supply and finally the atomizer air.
The material flow rate and the shape of the spray jet (wide / round) is adjusted with
regulating screws on the gun.
The PILOT WA 650 model (low-pressure version) with dual connector for material
supply can be integrated into a circulating system. This allows for the simultaneous
supply of several spray guns through the circular ring line with spraying material.
