Hardware Selection
The 16E / 16E-H / 16E-P Spray Guns are supplied, standard, with
hardware that will meet the needs of the most common combustion
wire. The specific hardware requirements are determined by combus-
tion gas, wire type, wire size, and conditions of use. This section pro-
vides an overview of the hardware available and its usage. More
detailed selection criteria are contained in the spray parameters, PAR
96447. Order numbers for all parts are provided in the parts list, PL
96151.
2.6.1 Front End Hardware
Front end hardware selection is mainly determined by combustion
gas, wire size, wire type and the duration of continuous spraying (e.g.,
part size).
•
The standard hardware is intended for spraying large areas where
the wire is continuously fed.
•
Short-duration spraying (start-stop operation) may cause loading
of material inside the air cap. Non-load air caps are intended to
minimize material loading.
•
Softer wire, with a lower melting point (e.g., babbit, tin, etc.), may
tend to “stick” in the nozzle during start-stop operation. Where rec-
ommended in the spray parameters, a non-load nozzle should
always be used. The spray rate with a non-load nozzle will be
somewhat less than with a standard nozzle.
•
Fan spray air caps provide a broad, flat spray pattern and may be
oriented horizontally, vertically or at any angle.
•
All hardware configurations use the standard nozzle nut (12E6)
and air cap body (11E1).

Drive Gears” on page 29.
