OPERATING THE SYSTEM
PART 2
• Workpieces must be prepared in accordance with the
requirements.
• All surfaces to be sprayed should be degreased using
a suitable degreaser.
• All surfaces should be GRIT blasted to the
specification required by the customer.
NB: 90% of coating failures are a result of poor substrate
preparation. These general rules should be followed prior
to spraying:
It is important that the valve lever is turned to the
fully open position. Also a steady action is important
- Opening too slowly will burn out the Air Nipple. Too
fast will blow out the flame.
If the flame is not burning correctly adjust the
oxygen flow at the supply regulator (DO NOT adjust
fuel gas). For a long hose system (i.e. 3/8” hoses)
adjust the oxygen flow at the board.
When the pistol is alight, the flowmeter floats will
change position. This is normal DO NOT try to re-
adjust parameters to get the flowmeter floats to the
‘before lighting’ settings.

To extinguish turn the pistol valve to the
OFF position (180° anti-clockwise in a
single smooth movement) but hold the wire
feed trigger for approximately 1 second
longer. NOTE: Turning the valve too slow
can cause damage to the pistol.
If the pistol is not going to be used for a period of time the gas
must be switched off and the hoses drained.
WARNING: The Spreader should always be turned in an anti-clockwise
direction (operator POV). Rotating in a clockwise direction could loosen
the air cover, potentially resulting in damage being caused.
Pull the trigger and adjust the wire speed until an acceptable sharp point of
wire is protruding from the Air Nipple (approx. 3 times the wire diameter).

If fitted adjust the spreader to give the desired direction of the spread.
Note: There is a position where air to the spreader jet is cut off.
If the spreader is not required, rotate spreader until it shuts off.
Spray perpendicular to the work.
Stand-off distance 4”-8” (100-200mm) travelling at a suitable pace.
Shut off the gas and oxygen at the supply points.
Open the pistol valve to allow the lines to empty.
Shut off the air at the supply point.
ONLY when these steps have been complete
should the extraction system be turned off.
Depress the lever and turn to the pilot position.
Turn until it stops (approximately ¼ of a turn).
Light the pistol and
allow the flame to stabilise.
Turn gas control lever to the fully open position using
a smooth steady action.
Pull the wire feed trigger to spray.
Note: the different flame colour when spraying.
General good
spraying practice.
Before attempting to spray, leak test the
system. Also, every time the system is
assembled and/or at least once per week.
