Due to differences in circuit design and function of
cascade style guns, standard current demand,
and short circuit current (SCI) test will not work.
(See Figure 4 for appropriate procedure.)

In some cases as a means of reducing current
draw to enable the use of metallic and some low
resistance coatings in REA type guns, a smaller
or reduced I.D. fluid tube or a coiled fluid tube may
be used. A similar device called the Shortstopper
may also be employed. In this instance, ground
shielded tubing is used uncoiled. By reducing the
fluid tube inside diameter, the following actions
occur:
1. The decreased size of the fluid tube increases
the velocity of the material, thereby reducing the
possibility of the metallic particles shorting to
ground.
2. The decreased inside diameter increases the
resistance to electrical flow, thereby reducing
current draw.
These methods have proven successful in most
installations, however, it is recommended that
testing be done with each individual coating material
to ensure the best performance.
Contact your ITW Ransburg distributor for the
current part number or latest techniques.
