Help with this LVLP gun

[eric_knapper]

I've just bought this LVLP spray gun http://tzhongtian.en.hisupplier.com/product-302213-RP-spray-gun.html

but the user manual is missing in the info in the link about it only mentions air pressure 45-80psi which can not be the working pressure if I set the gun regulator to 45 psi with the trigger pulled it blows paint all over the place and I also have to set my line pressuere to 80 psi to get 45 with the gun triggered. I thought these LVLP guns are supposed to be set with a low working pressure of about 20 - 30 psi I've looked at a few others on the net and that seems about right.

Yeah I would prefer HVLP I have a HVLP mini gun but I'm CFM limited so bought this LVLP gun for clear coating. I've just finished for the evening winding down the pressure with each coat I got down to 25psi at that level the overspray is much better but I'm getting some orange peel no matter what psi I used I tried a pass at 40/30 and 25psi it's not really bad orange peel but would require wet sanding and polishing.

if u have dropped the pressure and getting orange peel try thining the paint a bit more. practice on an old one gallon can 1st i have a jga gun setand run the pressure in the line at about 50psi it drops in use but ive never looked to see how much as theres no need

Im limited CFM wise too so just brought a Deltalyo LVLP gun and also have a mini Deltalyo HVLP gun that ive used for a while. Im a compete novice but i find the LVLP gun a lot easier to use.
Only advise i can offer is practice practice practice and find what settings work best for you.
