Manual 37-32

Problem

Possible Cause

Corrective Action

2. Powder puffing

from gun

Blockage in system

Shut down system. Clean system starting with

pump.

Pump venturi throat worn out

Change venturi throat.

Diffuser (atomizing) air pressure too

high or incorrect ratio of diffuser to

flow-rate air pressure

Decrease diffuser air pressure or increase flow-rate

air pressure.

Powder feed hose ID too large or

hose too short

Change to smaller ID hose or change hose length.

Best results are obtained when hose is 4

−

6 m

(13

−

20 ft) long.

3. Poor powder

charging—no

electrostatic

wrap or

adhesion

Flow-rate air pressure too high or

diffuser air pressure too low

Decrease flow-rate air pressure or increase diffuser

air pressure.

Parts not properly grounded

Check conveyor and hangers with standard

ohmmeter for coating buildup that could affect

ground. Resistance between parts and ground must

not exceed 1 megohm. For best results resistance

should not exceed 500 ohms.

Too much moisture in compressed

air supply

Check air dryer for proper operation. Use a

refrigerated or regenerative desiccant air dryer that

can produce a 3.4

C (38

F) or lower dew point at

7 bar (100 psi). Drain air filter and check filter

element.

Inner and outer wear sleeves worn

Disassemble gun. Reverse inner and outer wear

sleeves (turn end-for-end). Replace sleeves if

necessary.

Too many fine particles in powder

supply

Replace powder supply with virgin powder. Consult

with powder manufacturer.

Powder not suitable for

tribo-charging

Consult with powder manufacturer.

4. Inadequate

powder flow

Flow-rate air pressure too low

Increase flow-rate air pressure.

Wet powder clogging system

Check air filters, dryer, and powder supply. Service

filters and/or dryer and change powder supply.
