Iwata eclipse G6 airbrush gun - no paint flow, bubbles forming in gravity feed bottle.
it is rather large (usually 0.6mm nozzle) airbrushing gun,
symptom indicate that needle is closing the nozzle and not retracting, gun need cleaning! or adjustment - seem like both...
remove paint from the feeder, remove feeder bottle from the gun body, clean it well with paint stripper and then solvent/water allow it to dry
remove front casing from the gun and check for any physical debris around the needle or in the chamber, carefully clean without damaging the needle. needle is stainless should be nearly mirror finish.wash with solvent and use toothbrush - DO NOT USE METAL BRUSH!
put it back together and check if it works correctly, if you have any flow from the front - fill about 1/3 of the tank with paint stripper and then spray it to the sink or whatever other safe place. do not forget to wear safety mask, goggles and gloves! paint stripper will eat through your skin! if you splash yourself, have few spoon of vinegar mixed with 2pints (1 liter) of water and this solution will deactivate paint stripper! SAFETY FIRST!
if gun still do not work - you need to strip needle assembly and clean it correctly, put your gun on the table on butcher paper, remove screw holding needle on the back (watch for the spring!) put whole assembly on the paper in the order in which you removed it,
clean needle and needle seat, lightly grease it with vaseline and in reverse order put it back together.
very bottom screw - this close to the airhose, it regulates volume of the air to the gun, you very rarely need to adjust that one, you increase volume with haevy paint and decrease it with light paints
needle screw - it regulates volume of the paint itself, closing it clockwise will decrease amount of paint, anticlockwise will increase volume of paint
top screw - it regulates the spray pattern, totally closed - round pattern as there will be no flow to side vents, more open, more flat the spray pattern,
i would suggest fill the bottle with water and put some butchers paper on the wall and experiment what is what and what pattern is most suitable for your use.
hope this little info will help you solve your problem, it is good you give the model, it will be better if you provide as well what medium you use, was it acrylic, oil, water based? all of them behave little bit differently in airgun...
please do not hesitate to leave your opinion and points... thanx!
