Section 2Description

The Sure Coat automatic powder spray gun electrostatically charges andsprays organic or metallic powder coatings. The spray gun is used witheither a Sure Coat individual controller or modular gun control system.

See Figure 2-1.

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 inspect, clean, and remove.

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 inlet connector (1) allows the operator to quicklyswitch powder feed hoses while performing a color change.

The spray gun is available in three lengths:

0.91 m (3 ft) 1.22 m (4 ft) 1.52 m (5 ft)

Description2-2


334 627BIssued 3/01

Manual 31-46

See Figure 2-1.

The Sure Coat individual controller or modular gun control systemsupplies low-voltage dc power to the voltage multiplier in the spray gunhousing (2). The multiplier converts the low-voltage dc power to the highelectrostatic voltage needed for powder coating. The voltage generatesa high-strength electrostatic field between an electrode in the nozzle (3)and the grounded part in front of the spray gun. The electrostatic fieldproduces a corona discharge around the electrode.

Flow rate air pressure pumps the powder from the feed hopper, throughthe feed hose, into the inlet connector (1), and out through the spraygun’s nozzle. As the powder particles are sprayed past the electrode inthe nozzle, 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 rateair pressure, and the electrostatic field generated between the electrodeand the grounded part.

WARNING: Turn off the electrostatic voltage and ground thegun electrode before performing the following tasks. Failure toobserve this warning could result in a severe shock.

NOTE: Depending on your system’s operation, you may not need toperform this procedure every day. If you regularly perform color changeswith a powder feed center, the spray gun will be purged internally eachtime a color change is performed. If this is the case, perform thisprocedure every 2–3 days.

See Figure 4-2.

1. Disconnect the powder feed hose from the powder pump. Blow thepowder out of the powder feed hose and gun with an OSHA-approvedlow-pressure air gun. Never blow air through the powder feed hosefrom the gun into the powder pump.

2. Unscrew the nozzle nut (5).

3. Pull the nozzle (4) off the spray gun with a slight twisting motion.

4. Pull the electrode support (3) straight out of the spray gun (1). Thepowder feed tube (2) will come out with the electrode support.

5. Clean all parts with a low-pressure air gun. Wipe the parts with aclean, dry cloth.

6. Carefully remove fused powder from the parts with a wooden orplastic dowel or similar tool. Do not use tools that will scratch theplastic. Powder will build up and impact-fuse on scratches.

NOTE: If necessary, use a cloth dampened with isopropyl or ethylalcohol to clean the powder path parts. Remove the O-rings beforecleaning the gun parts with alcohol. Do not immerse the spray gun inalcohol. Do not use any other solvents.

7. Inspect the powder path parts for wear. Replace worn parts.

CAUTION: Do not overtighten any threaded parts.Overtightening threaded parts may result in stripped threads orcracked parts.

Manual 31-46

NOTE: When you install the nozzle, there will be a gap between thebase of the nozzle and the front of the gun. Rotate the nozzle at least90 from its previous position to prevent uneven wear and lopsidedpatterns.

CAUTION: The nozzle nut and the inlet connector body at theback of the gun hold the powder path components together. Ifboth are not tightened, gaps may appear between parts,allowing for powder to build up and cause contamination duringcolor changes.

8. Assemble the gun. Tighten the inlet connector body at the back ofthe gun to ensure that there are no gaps between the powder pathcomponents.

Check the resistance of the multiplier and resistor assembly with amegohm meter as described in the Troubleshooting section. Replace themultiplier or resistor assembly if the resistance readings are not within thespecified ratings.
