2.1 Introduction to the MK73
This hand held flame spray pistol is designed to produce coatings from wires of
all common sizes, and is able to accept wire sizes from 1.5mm to 3/16”.
This pistol is primarily recommended for anti-corrosion and tool making
applications, electronics and other instances where the main coatings produced are
from the lower melting point materials e.g.: Zinc, Aluminium and other similar alloys. It
is also suitable for use with some of the Engineering Wires e.g. Steels and Bronzes.
The MK 73 boasts the following features:

A rugged construction, which is designed to meet all the requirements of the practical
metal sprayer.

A Propane fuelled gas head valve, spraying anti-corrosion or similar coatings at very
high speed.

A high torque positive displacement air motor which feeds the wire, doubling as the
pistol handle.

A pressure compensating valve built into the exhaust port of the motor which provides
variable speed control, to cater for materials with different melting points.

A nozzle system that is designed to ensure true axial alignment of the component
parts, all mating faces being provided with push fit gas seals for simple leak proof
assembly. Excellent flame stability and easy lighting is afforded by the pneumatic self-
adjusting air nipple.
**An adjustable spreader providing a wider spray pattern is
available as
standard on 3/16” and 1/8” systems, which can be turned on/off during
spraying.

A multi diaphragm main valve, supplying air, fuel gas and oxygen to the gas head.
The sealing diaphragms are operated collectively by a pre-set cam. Internal leakage
between fuel gas and oxygen ports is impossible and the sequence in which the
various gases are released to the gas head cannot become out of phase.

An easily operated pilot valve, which allows the pistol to be lit by numerous methods,
i.e.: spark gun, cigarette lighter
etc…

Fingertip operation of a trigger valve, located on the motor inlet. This ensures
instantaneous stop/start control of the wire feed.

An exclusive patented feature of the stop/start system is the provision of an air heat
shield at the nozzle, which automatically prevents the wire melting back and becoming
welded to the nozzle when the wire feed is stopped.**
**This facility is not available in
‘continuous spray mode’.
