INTRODUCTION

GENERAL DESCRIPTION

This is a method of applying electrostatically at-
omized coating material. The No. 2 Electric Pro-
cess Handgun system applies a high voltage,
DC negative charge to the applicator bell, creat-
ing an electrostatic field between the bell and the
target object. The target is electrically grounded
through its support (which may be stationary or
moving) or through an electrical connection to a
known earth ground.
A regulated pressure fluid system delivers
coating material to the electric motor driven
bell when the gun is triggered. There, the fluid
travels across the face of the rotating bell and
is charged. The fluid is atomized at the edge
of the bell forming a fine mist, which under the
influence of the electrostatic field is attracted to
and deposited on the target object. The forces
between the charged particles and the grounded
target are sufficient to turn most normal over-
spray around and deposit it on the rear surface
of the target. Therefore, most of the spray is de-
posited and overspray is controlled. This pro-
cess makes the No. 2 Electric Process Handgun
one of the most efficient electrostatic spray prod-
ucts on the market.
The No. 2 Electric Process Handgun applies
a DC negative charge to the coating materials
at the point of atomization. The electrostatic
charge allows a more efficient, uniform applica-
tion of coating material to the front, edges, sides,
and back of products, making it highly suitable
for applying coatings to a variety of surface con-
figurations; large targets, tubular products, small
parts, fencing, etc. Because it is a grounded
fluid system, it is highly suitable for applying a

wide range of solvent reduced coatings such as
enamels, epoxies, etc.
One of the many features of the No. 2 Electric
Process Handgun is that the electrical discharge,
which is available from the resistive charging
brush, is limited to the optimum combination of
safety and efficiency.
The No. 2 Electric Process Handgun system in-
cludes the Hand Gun, the High Voltage Power
Supply, the High Voltage Cable, and Fluid Hose.
This unit contains the 19372-XX No. 2 handgun
electric motor version and the 80102-21X 9060
power supply along with several required ac-
cessories. Below illustrates the ordering matrix
available.
