Wagner Product Training

Safety Considerations and
Recommendations
As with any power tool, you need to exercise a level of care to ensure user
safety.
Wagner products used correctly are very safe, and meet all of the necessary
safety requirements.
There has not been a reported case of skin injection injury in over 10 years,
but safety should always be high priority
2

Safety Considerations and
Recommendations – cont.
1. Before using the equipment, read and observe the safety instructions detailed
in the Users Manual.
2. Make sure the electrical lead is in good working condition.
3. Spray materials emerge from the nozzle tip under high pressure. Never point
the spray stream towards human beings or animals. In the event of injury to
the skin by paint or solvents, quick expert treatment by a physician is
essential. The physician should be informed of the type of paint or solvent
involved.
4. To avoid the hazard of explosion when spraying, provide for effective natural
or artificial ventilation.

Safety Considerations and
Recommendations – cont.
5. No sources of ignition are to be in the immediate area when spraying eg.
open flame, cigarettes, sparks, glowing wires and hot surfaces.
6. The spray gun is not a toy. Keep out of reach of children.
7. Before carrying out any type of work on the spray gun, unplug the lead from
the power socket.
8. Do not use spray guns to spray flammable liquids.
9. Do not spray any liquid of unknown hazard potential.
10. Wear a breathing mask or ear protection as required.

Air Spray
Process
Paint is drawn into the gun by venturi
and is a atomized by injected air. The
fan can be manipulated by air
introduced around the fan. Because
the paint is both picked up and
atomized by air the paint leaves the
nozzle in form of a fine mist. The paint
droplets are suspended in the air and
tend to float, causing overspray. The
transfer efficiency is very low, only 25-
45% of the coating reaches the job
Advantages
• Adjustable air control
• Adjustable fluid control
• Fan width adjustment
Disadvantages
• Poor transfer efficiency
• Overspray

Airless Spray
Process
Paint is drawn into the gun by
vacuum and is pressurised. It is
forced trough a small orifice causing
it to atomise. The paint is delivered
to the job by pressure only, therefore
there is little overspray although you
do get fallout. Due to fixed tips a
percentage of the paint can be
sprayed past the job. The transfer
efficiency of an airless gun is 65-
80%
Advantages
• Fast coating time
• Good transfer efficiency
• Low overspray
Disadvantages
• Fixed tips
• Not adjustable

Functional Principle of Electric Hand
Spray Guns
The heart of the airless unit is the
piston which causes atomisation
by high pressure.
The oscillator pushes the piston
forwards. As soon as the piston
spring moves the piston backwards,
a vacuum is set up in the pump
cylinder and this sucks in the
spraying material. In the next
forward movement of the piston, the
suction aperture is closed and the
spray material is pressed outwards
under high pressure through the
valve system – with no air.
The spray flow rate and the
spraying pressure can be
smoothly adjusted with the
regulating screw
