I have a craftsman HVLP Spray gun. Even when we thin the paint, the paints comes out in sputters or not at all. What could be the problem?


the passage might not be cleaned and is blocked.
take the air cap off make sure u can see all the holes thru the lights. take the nozzle and the cup off. see if there's any build-up inside that might possibly block the paint coming out.
over all, clean the gun good with thinner

On a Campbell Hausfeld DH5030 spray gun, there is a screw valve at the base of the unit with arrows labeled S and P for turning clockwise and counterclockwise, respectively. What is this for?


The "P" stands for pressure feed. turning it completly to this side forces air into the cup pushing the paint out.

The "S" is for siphon feed where the air through the tip sucks paint from the cup.

If your using thin materials like lacquers or polyurethane or solvent based enamels the siphon feed is used.

If your using thicker materials like water based latex or heavy stains then go with the pressure setting.

You can always go in between for some pressure with the siphon action....depends on coatings used.

Why does my gun keep spitting


Spitting is usually caused by not filtering the paint through a strainer (made for the purpose by the paint manufacturer). The paint debris blocks the paint for just a moment, then spits it out. Easy fix!

ORANGE PEEL


Orange peel can be a really hard problem to diagnose. There are a number of things that can affect the spray pattern. I would start by doing some test spraying. Your air pressure is going to be a factor as well as the ration knobs on the gun. I would start by increasing the air pressure to the gun. Keep in mind that if you're regulator is at the tank the actual pressure at the gun is going to change based on the length of hose used. Generally speaking, more air pressure will disperse the fluids better, better dispersal better/smoother coverage. I'd start there and then tune on the knobs to adjust it. Keep playing with it until you get a pattern you're happy with. Then when you're done with that write down how many turns on each knob, and exact pressure, length of hose etc. This way when you clean the gun you can get it exactly the way you want it. Different products will also spray differently. You may need to adjust for each step in the painting process. I just had to go through this on my new gun and it took about an hour and a pint of clear to get it spraying well. Check out tcpglobal.com for paint and supplies. They have great prices and they also have a forum on painting. I am a user of their products and forum.

I have constant air pressure out of hvlp nozzle without pulling handle


have you tried to adjust the air regulator on the rear of the gun! there should be two adjusters, one to adjust the paint flow rate and the other to adjust the air flow rate! if you have tried this then the rubber sealer has perished inside the gun! unscrew the controller and replace the seals!
kind regards

There is only air coming out of the gun without any paint/material. i can feel the material inside the canister bubbling but nothing is happening


Check that valve inside the canister that let the air in and make sure it works freely. Then you'll need to make sure your paint isn't too think. If it is you'll need to thin it.

I tried to adjust the regulator and the back just screwed off of the body - any ideas on how to prevent that?


Possibly you were trying to adjust the regulator without having air flowing through it. You must squeeze the trigger on the gun and have air constantly flowing through it otherwise the regulator knob is very hard to turn against the pressure inside it. To set an accurate pressure, squeeze gun trigger (while connected to air hose) to get air flowing... then twist regulator knob out (or in the "-" direction) until air flow reads 0 on the regulator gauge. Then start twisting regulator knob the other way until you reach the desired pressure on the regulator gauge. Also make sure the regulator is attached with air flowing the correct way through it. There should be an arrow somewhere on the regulator body which should be pointing toward your spray gun.

IR 210g - using thicker paint


i dont have so much as a solution as a couple of things you can try to figure out whats going wrong.

make sure your compressor can handle 10.5 CFM @ 50psi
hook up the gun and dry spray it to check for blockages in the air supply
if the air comes through strong and constant, fill the paint hopper with water and spray until empty
if the water comes through constant, add half of the hopper with paint thinned with penetrol or floetrol
if the paint is coming out weak or spotty, make sure the vent cap is open on the paint hopper
if the cap on the hopper doesnt have a vent, try spraying with the cap off or cracked a bit.
if that doesnt work take off the hopper and check the filter for blockages.

i suggest straining all your paint before pouring it into the hopper
