Operations:
Hang the article(s) to be coated in the spray booth or in a safe
1.
enclosure, ensuring that they are properly earthed (grounded).
Switch ON the mains power switch to the machine from the wall
2.
power outlet. The indicator (if provided) on the wall-mounting power
adaptor should light up.
Switch on the compressed air supply to the machine and set the
3.
pressure at around 20 - 30 psi.
Point the gun into the booth towards the grounded articles to be
4.
coated and press the trigger on the spray gun. The indicator at the
back of the gun (yellow) should light up. The Digital Meter will
indicate the (nominal) charging voltage available at the tip of the
gun. Turn the kV controller knob (at the back of the gun) clockwise
to increase the charging voltage to the max – approx 100kV. The
range available is approx from 20kV to 100kV. Turn the flow
controller clockwise till you achieve powder flow at a rate and
density of satisfaction to you.
Keeping the nozzle of the gun about 10 to 20 cms (4" to 8") from the
5.
articles being coated, spray powder in smooth horizontal arm
sweeps. Ensure that the part to be coated is completely coated with
powder. Excessive coating may lead to unwanted and unnecessary
thicker coats.
Releasing the trigger of the gun switches OFF the powder flow as
6.
well as shuts down the electronics used to generate and control the
high voltage. Please note that your powder spray gun may still
hold electrostatic charge. To prevent any accidents, please touch
the charging tip to a ground point to discharge any residual
electrostatic charge.
Place the coated article in the oven which has been preheated to
7.
the required temperature (350 - 390
curing time with the powder manufacturer (this information may be
available on the powder carton or from the powder supplier). Keep
the article in the oven for the desired time. At the end of the curing
period, switch off the oven, open the door of the oven, allow the
parts to cool and remove them. Please note under-curing or over-
curing (temperature or time) could give you unwanted results.
Your part is ready, duly powder-coated.
