Part 334627−05� 2015 Nordson Corporation
Section 2Description
IntroductionThe Sure Coat automatic powder spray gun electrostatically charges andsprays organic or metallic powder coatings. It is used with a Sure Coatautomatic gun control unit, or a Sure Coat Modular Gun Control System, oran iControl system.
FeaturesSee Figure 2-1 or 2-2.
The spray gun features a straight-through powder path, which minimizessurfaces for impact fusion to occur. The rigid powder tube and all powderpath components are easy to remove, clean, and inspect.
The negative-polarity, integral power supply (voltage multiplier) isuser-replaceable. All spray guns are equipped with gun air to preventpowder from collecting on the electrode.
The quick-disconnect hose connector (1) allows the operator to quicklyswitch powder feed hoses while performing a color change.
Mounting Configurations The spray gun is available in both bar- and tube-mount configurations.
Refer to Table 2-1 for a description of the variations available for bothmounting configurations.

Mounting Configurations (contd)
Table 2-1 Mounting Configurations
Gun Type Variations Illustration
Tube-mount The tube-mount gun is available in the following lengths:
� 0.91 m (3 ft)
� 1.22 m (4 ft)
� 1.52 m (5 ft)
� 1.83 m (6 ft)
Figure 2-1
Bar-mount The bar-mount gun may accept either of the following size gunbars in any lengths:
� 11/4-in. OD
� 5/8-in. OD
NOTE: The 11/4-in. OD gun bar is a new, larger diameter, rigidbar. Refer to Parts for ordering information for the standard 3-and 4-ft long gun bar mounting assemblies.
Figure 2-2
Theory of OperationSee Figure 2-1 or 2-2.
The control unit supplies low-voltage dc power to the voltage multiplier inthe spray gun body (2). The multiplier converts the low-voltage dc power tothe high electrostatic voltage needed for powder coating. The voltagegenerates a high-strength electrostatic field between an electrode in thenozzle (3) and the grounded part in front of the spray gun. The electrostaticfield produces a corona discharge around the electrode.
Flow rate air pressure pumps the powder from the feed hopper, through thefeed hose, into the hose connector (1), and out through the spray gun’snozzle. As the powder particles are sprayed past the electrode in thenozzle, they pick up an electrostatic charge and are attracted to thegrounded parts.
The spray pattern is controlled by the shape of the nozzle, the flow rate airpressure, and the electrostatic field generated between the electrode andthe grounded part.
