AB. Trigger functions.

As was said, the trigger is for on and off only and the pressure is regulated at the regulator.

This is how it has been for many, many years and it works great. I see no need for any other gimmicks on airbrushes IMHO.

As regards to the trigger functions on single and double AB`s. Is the air variable by the trigger on one or both? I only ask because today i the first time i have held one and was surprised at how very little the trigger moves on a Badger 200. Is the airflow basically on or off?

These are my experiences with 3 airbrushes. I am not an expert on AB.

(1) Paasche Model H external mix, single action airbrush. The trigger controls the air flow. There is an adjustable stop for the trigger travel distance. The control for amount of air is a "hit and miss", not very precise.

(2) Iwata Eclipse HP-CS trigger have very short vertical travel. It is almost like an on-and-off only. The amount of paint control (back and forth) is smooth and percise. I like this the best.

(3) Powercat 800 internal mix, double action siphon feed airbrush. It is a Badger 155 knock-off. It has the longest trigger vertical travel and more control of the air flow. It is actually more difficult to control the painted line width and color. It takes more skill. Most of the time, I just push the trigger all the way and use the horizontal travel to control the paint.

Some of the higher end Iwata has a "Micro Air Value" which is a small turning knob under the AB. I tried one and found that it does a wonderful job providing precise control of the air amount.

Yep, generally, on both single and double-action airbrushes, when you depress the trigger the air is either on or off. Air pressure is adjusted at the regulator.

And yes, the B-200 does have a very short trigger travel.
