Description

IntroductionThe Tribomatic II manual powder spray gun uses friction to electrostaticallycharge powder coatings as they are forced through the gun by compressedair. The spray gun is used with a Vantage� control unit and a Tribomatic IIpowder pump.

The spray gun can be retrofitted into an existing Nordson Tribomatic orVersa-Spray system and used with older-style Tribomatic powder pumps. Itis equipped with a 6-meter (19.7 ft) trigger cable.

Figure 1 Tribomatic II Manual Gun

The spray gun is made of PTFE and Tivar. These materials are used withmost organic powder coatings. Table 2 describes the characteristics ofTivar and PTFE and their use.

Table 2 Material Description and Usage

Material Appearance Usage

Tivar Greyish, translucentwhite

Standard material for inlet and outlet distributors and wearsleeves in manual guns. Longer wear-life than PTFE, butsome powders may impact-fuse to Tivar. Switch to PTFE ifimpact-fusion is a problem.

PTFE Opaque white Standard material for inlet and outlet distributors and wearsleeves in automatic guns. Optional for manual guns. Shorterwear-life than Tivar, but reduces or eliminates impact-fusion.

Refer to Options on page 28 for optional equipment for this spray gun.

The sprayheads and nozzles used with Tribomatic automatic spray gunscan be used in place of the standard nozzle and deflector shown inFigure 1. Refer to the Tribomatic Optional Nozzles and Sprayheads sheet,part number 1040999A.



Spray Gun ComponentsSee Figure 2.

The charge module can be disassembled without any tools. It connects tothe body with a bayonet-type mounting. Two O-rings hold the diffuser in thebody. A ground pad on the handle connects the operator to ground throughthe trigger cable and control unit to prevent shocks.

Theory of Operation Flow rate air pumps powder out of the feed hopper and forces it through thefeed hose to the diffuser. Diffuser air mixes with the powder at the spraygun and increases the powder velocity. The powder and air mixture passesbetween the inner and outer wear sleeves inside the charge module. Thecollision of the powder particles with the walls of the sleeves electrostaticallycharges both the powder particles and the sleeves.

The sleeves are grounded through the spray gun body, trigger cable, andcontrol unit. The charge picked up by the sleeves is displayed inmicroamperes at the control unit. The display indicates how well thepowder is charging (the higher the number, the stronger the charge thepowder is receiving). The strength of the charge the powder receives willvary depending on many factors, including the powder type and its velocitythrough the spray gun.



Installation WARNING: Allow only qualified personnel to perform the following tasks.Follow the safety instructions in this document and all other relateddocumentation.

WARNING: All electrically conductive equipment in the spray area must begrounded. Ungrounded or poorly grounded equipment can store anelectrostatic charge which can give personnel a severe shock or arc andcause a fire or explosion.

Operation WARNING: Allow only qualified personnel to perform the following tasks.Follow the safety instructions in this document and all other relateddocumentation.

WARNING: The operator must maintain skin contact with the ground pad inthe spray gun handle. If wearing gloves, cut away the palm. Failure toobserve this warning could result in a severe shock.

WARNING: Before spraying powder or cleaning the gun with compressedair, make sure the trigger cable is connected to the control unit and thecontrol unit is grounded. A potentially dangerous charge could build up inthe spray gun unless it is grounded.

WARNING: Versa-Spray, EXP-100, and Vantage control units weredesigned to be used with corona-type spray guns with internal high-voltagepower supplies. Turn off electrostatic voltage at the control unit when usinga Tribomatic II spray gun with one of these control units.

Air Pressure SettingsFlow-rate and diffuser (atomizing) air pressures made at the gun control unitcontrol the powder velocity, flow rate, and atomization. As a starting point,set air pressures to

Flow-rate air pressure: 1.8 bar (26 psi)Diffuser (atomizing) air pressure: 2.5 bar (36 psi)

These pressures can be adjusted to obtain the desired results as follows:

� Increase the flow-rate air pressure to increase the film build; decrease itto decrease the film build.

� Increase the diffuser air pressure to increase the powder velocity andelectrostatic charge on the powder; decrease it to decrease the charge.

Daily Maintenance 1. Remove the powder feed hose from the pump. Make sure the booth

exhaust fan is on. Point the gun into the booth and blow out the hose,diffuser, and gun with compressed air.

NOTE: Always blow out the feed hose in the direction of powder flow (frompump to gun). Never blow out the feed hose from the gun back into thepump.

2. Remove the diffuser from the gun. Remove the diffuser nozzle. Cleanthe nozzle and housing with low-pressure compressed air and a clean,soft cloth.



Daily Maintenance (contd)

3. Remove and disassemble the charge module. Clean all the parts withlow-pressure compressed air and a clean, soft cloth. Disassemble andclean the lance extension (if it is used).

4. Disassemble the powder pump and clean all the parts with low-pressurecompressed air and a clean, soft cloth.

NOTE: Never use a knife or other sharp object to clean the gun or pumpparts. Powder particles will build up on scratches, fuse together on impact,and clog the gun and pump.

WARNING: All electrically conductive equipment in the spray area must begrounded. Ungrounded or poorly grounded equipment can store anelectrostatic charge which can give personnel a severe shock or arc andcause a fire or explosion.

5. Make sure all equipment ground wires and straps are securelyconnected to a true earth ground.
