Any one know what is in the gun part on powder coat gun, any electrics/wires or is it just metal that the main wire from the unit goes to ?
The only wiring in the gun is an earth strap which you'll see attached to the air inlet and the high tension wire that goes to the electrode.
Cleaning the gun after blowing flock though it is exactly the same as cleaning between different coloured powders, I keep a separate pot so I'm not wasting flock by cleaning it out all the time.
