Problem
Cause
Solution
Poor wrap.
Turbine air is not turned on.
Turn on.
Booth exhaust velocity is too high.
Reduce velocity to within code limits.
Atomization air pressure too high.
Decrease.
Fluid pressure too high.
Decrease, or replace worn tip.
Incorrect distance from gun to part.
Should be 8-12 in. (200-300 mm).
Poorly grounded parts.
Resistance must be 1 megohm or
less. Clean workpiece hangers.
Faulty gun resistance.
See
Test Gun Resistance
