double action air-brush

[DK2670]

I have a double action air-brush (Güde) that really needs an instrucion book so I can tell it how to work!

It delivers paint right from the instant I press the button down, and not just when I pul it back. Also when the paint comes out, IT COMES OUT, if you know what I mean.
Understanding that these things are quite generic in their construction, use and adjestment, I figure that there must be some one here that can give me a mini tutorial in setting up and adjusting the :censored: thing so I can use it!!!

DK, DO you know the make and model of air brush you have ??,also if paint comes out the second you push down you may wnat to check your spring and o-ring to where your air hose hooks up to the brush.

The air-brush was sold in a set from GÜDE, but the airbrush its self looks a lot like a badger.
I tried their (güde) website but its in German and really not that helpful. To me at least.

By pushing the button down you start spraying. The further you pull that button back, the more paint/air comes out. And that's so 'general' a thing that there's a huge amount of 'technique' in doing either/both correctly. Practice! Pay attention! Those are the two things that have done me the most 'good'. (Not that I do it 'right' by any means, cuz I still have no idea about how to do it right.)
There are some tutorials on the internet. 'Noodle' around and take a look. Since they are not directed primarily to your airbrush, you probably will have to 'adapt' what they say to suit yours, but you'll get a sort of general idea of how to do things.

If you should happen onto the 'perfect' set of instructions, I really hope you tell me where to find them too!

More than likely, the nozzle at the front of the airbrush has been opened all the way. Perhaps it was left in that position the last time the previous owner cleaned it.

The nozzle is threaded and rotates. So, while pushing down the air button, start rotating the nozzle. You should see the paint flow start to decrease. You want to decrease it to the point there is almost no paint flowing, when the air button is all the way forward. Then pull the air button back and you should see paint flowing (spraying) again. Now, with the air button fully back, rotate the nozzle until you get the maximum flow of paint you desire. From that point on, as you are airbrushing the amount you pull the air button back will determine how much paint you let out of the nozzle.

DK, On my paschie when I press down you should get only air I use this to help "dry" the paint so to say you may wnat to take the needle out and the tip make sure they are clean,Like Doc said jsut fool with the setting till you have them set as you want then get some cardboard and start making lines and and go from there and remenber what works for someone eles may not work for you and don't worry the "airbrush" police will not come to get you :D

If it is a true double acting airbrush, the up and down motion should control the air flow and the back and forth motion the paint flow.
If you have to rotate the nozzle to control paint flow then you have a single action airbrush.
Both work in the same way, in that air flow over the nozzle sucks paint up through the tube, and the ammount of paint is determined by the size of the opening. If you are getting what seems to be way too much paint and there is no way to shut it off, maybe you are missing a part somewhere.
How about a picture?

After removing both the needle and the nozzle for the umpteenth time and puting them back. Adjusting the needle in the collet and locking in down th airbrush is now working as intended. push button, air starts, pull back and the paint starts.

Problem solved me thinks.

Thanks for the ideas.

Great to hear DK :D when you can post a pic and just have fun!!! :cool:

I have a Paasche double-action airbrush. It is possible to set it up to duplicate the issue you are having. You are basically putting the double-action brush into single action mode with a given set-up. I've done it when playing around with it and the needle/nozzle sets. I actually use it in that mode sometimes for large area work as it works like a rattle-can at that point.

If that's a higher end brush, you likely have several needles/nozzles that came with it. If you have too fine of a needle used with too thin of a paint, I found you can do what you are describing. Paint viscosity is critical to needle (nozzle) choice and settings.

If your brush is configured correctly, when the button is all the way forward you should get either very fine (light) paint mist or none at all (your choice), but you should get air flow. As you draw the button back, the paint should go heavier.

At least, that's how it is with my airbrush. Double-Action is harder to setup and configure for proper use than single action, or so I've found anyway.

Well it's been covered on the proper set up, but the airbrush with the trigger all the way forward should have NO PAINT come out when you press the trigger down, no paint just air. If you do have some paint come out, it will dry in the tip and cause problems.
I have 5 air guns.... 2 Iwata's, a Sata mini-jet, a full size hvlp, and a touch-up generic gun. I had a 6th and sold it.

[Shaun Hendricks]

I sometimes set mine up to have a light mist come out at full forward just so I have some single action simplicity there or when I need a precise flow and I don't trust my forefinger to be precise.

I did a 'soft' splatter design on a car lexan body this way using a bright gold. Followed it with a splatter of 'silver' and then a full coating of metallic red. It came out awesome.

So, you can cheat with a double-action gun, it doesn't HAVE to be no paint but you do have to understand how your gun works to set it up like that.

TIP: To keep paint from drying in the nozzle, dunk the nozzle into a cup of solvent (thinner, water, denatured alcohol, etc.) if you are setting the brush down for any length of time. Just enough to cover the spray port is sufficient. (I then use the same cup while changing colors or cleaning the gun up at the end of the work.)
