Any material that can
be used to
adhere
or
"sticK'
one
surface to another.
That
part
of
the hot melt system that is used to
heat adhesive to
its
required application temperature
and
pump
it to the
hose(s) and
gun(s)
It consists of a tank
or reservoir,
pump,
filter, distribution
manifold and
temperature controlled
heating system.
The width of an adhesive

The degradation of a fluid that occurs as a
result of time and exposure
to
atmospheric air and/or heat.

electronic
device that acts to shut down a
powered
AC circuit
when
current draw
(amps)
exceeds some
preselected
value
or
when certain
fault conditions exist.
The
amount
of materialflowing through the system
per
unit of time.
The
amount may be expressed
in
gravimetric (weight)
or
volumetric terms.
Examples:
g

gal
lo ns/hou r.
A wire
that
connects all AC
powered
devices to earth
ground.
A replaceable resistive heating element, tubular
in
shape,
designed to
fit
in a machined hole
in
the
object
to
be heated.
The adhesive or thermoplastic
material dispensed by the hot melt
system.
The
applicator,
