9040 Classic for the No. 2 Process Handgun - Introduction

GENERAL DESCRIPTION

The Ransburg

The Ransburg
No. 2 Handgun Process

No. 2 Handgun Process

The No. 2 Process

is an electrical atomization

method for applying coatings to objects electro-
statically. The No. 2 Process

Handgun system

applies a high voltage, negative, DC charge to
the applicator bell, creating an electrostatic field
between the bell and the target object. The tar-
get is electrically grounded through its support
which may be stationary or moving; or through
an electrical connection to a known true earth
ground.

A regulated pressure fluid system delivers coat-
ing material to the bell when the gun is triggered.
There, the fluid travels across the face of the
rotating bell and becomes charged. The fluid is
electrically atomized at the edge of the bell form-
ing 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 almost all overspray around
and deposit it on the side and back surfaces of
the target. Thus, a high percentage of the spray
is deposited on the target and overspray is con-
trolled.

Power Supply

The 9040 Classic Power Supply converts stan-
dard AC line voltage to a high frequency, low
voltage signal ranging from 0 to 10 Vrms. This
signal is supplied to the High Voltage Multiplier
where it is converted to DC high voltage. The
high voltage DC is then transferred from the
9040 Classic Power Supply to the No. 2 Pro-
cess spray gun through a super flex high volt-
age cable. The voltage/current characteristic is
designed to optimize the charging process un-
der varying load conditions and to limit the oper-
ating current to a safe maximum value.

In addition to supplying high voltage output to
the spray gun, the 9040 Classic power supply
also provides controls for AC power ON/OFF, a
high voltage meter, a current meter, a POWER
ON indicator, a HIGH VOLTAGE ON indicator,
and a CURRENT OVERLOAD indicator and
reset switch. Additionally, output terminals are
provided for remote overload reset and interlock
connections for a conveyor, exhaust fan and
high voltage control on all 9040 Classic Power
Supplies.

The 9040 Classic No. 2 Power Supply

is factory supplied with a cabinet latch
that can be opened using a slotted screw-
driver. If desired, the standard latch can
be easily replaced with a latch that re-
quires the use of a key to open. This key
lock can be ordered from: Austin Hard-
ware, Inc., 8001 Central Ave. N. E.,
Minneapolis, MN 55432; 1-800-328-2423;
Key Lock Part Number: C8052-14A.
