I don't even know where to start.



Well first off, I want to say thank you all so much for all the tips and ideas to help me with getting started on airbrushing. But now I have noticed a few other things and I have not been able to find out the answers.
I am using an Iwata HP-C Plus with a .3mm.

Issue: I have noticed that if I very slowly push down on the trigger I get a TON of air shooting out from the airbrush but also some paint as well. Not a lot I mean if I hold the airbrush very close to the paper and WITHOUT pulling back for paint, just lightly pushing down on the trigger I get really really fine lines of paint. If I push the trigger all the way down the air flow becomes normal and the paint stops until I pull back for the paint.

I am sorry for all these questions but I want to say thank you all for such a great community here. You are ALL very helpful and knowledgeable with solving problems. Again I don't know if this is normal or is something wrong. Thank you for any tips or ideas.
Hey no worries hun, we all go through this. Your needle isn't seated all the way into the nozzle, either because it didn't get seated when you last cleaned it out or there is a speck of gunk in there keeping it from sealing when you release the trigger. Loosen the chucking nut, give the needle a nice little "twist push" (gently), re tighten the chuck and see if that works. If not, then it's gunk. Put some cleaner (I use the clear windex for waterbase) in there, backflush (block the air either by pinching with your fingers or pulling back the needle and shooting into a soft rag to make it bubble back into the cup), dump, shoot, pull the needle back and forth via the chucking nut (that way you'll not accidentally damage the nozzle) blasting out whatever is caught in there. After that's all said n done go back and do the twist push thing again, reseating the needle. Remember, BE GENTLE!!!

As for the gush of air when you first pull the trigger, I am inclined to think that it's the pressure built up behind the brush being released and then normalizing down to what you have it set at. I've not seen many people, especially beginners being able to control airflow by trigger pressure alone, it's either on or off.
If its a new brush this prob wn't be an issue but get out a magnifying glass and check for any nozzle cracks or damage..Likely its what BG suggested..A bit of dried paint..GL
Thank you both for the tips. I will try this later this morning after the kids are off to school. I think this is by far the best forum I stumbled across while reading about airbrushing. You ALL are fantastic people!
if you are using the brush from new, and havnt stripped it down , played with it, cleaned of factory gunk etc etc etc..... you will probably find the needle is seated a little further back to help save damage in transit, i know this is what badger do with all their brushes so it would make sense iwata do the same..... follow steps above, undo chucking nut twist your needle forward until it stops, retighten chucking nut..... job jobbed!!!
So I took it all apart cleaned it 100% and I DID notice as I was putting the needle in I felt a little pressure. I am guessing that is the seal I kept reading about. When I pulled the needle back out it was covered in paint. I had to look up and see how to clean the inside of the body because I have read 50% of the people say never soak the body and the other 50% say go for it lol. Anyways, I got all the paint that was there out replaced the needle and all was PERFECT!. Sprays great no issues at all. Once again I have to say thank you to you guys for helping me out with yet again another issue.
no matter what kind of problems you have, ask and someone will come on the help!!!that´s why this is for me home!!!:loyal:
