Top 5 Tips To Help You Adjust Your Iwata Spray Gun To Produce Amazing Paint Jobs

We started using an Iwata spray gun several years ago at the school I teach. After using the gun, I loved it. Most students who have no preferences also choose the Iwata as their weapon of choice. So if you are looking to buy a new gun, I highly recommend an Iwata spray gun. The Supernova with 1.3 is my favorite. However, the tips that I am going to share can be applied with any gun.

1. Adjust the air pressure

The first thing I usually do is adjust the air pressure. Be sure to refer to the technical data sheet for the product to be sprayed. This data sheet will give you a recommended air pressure setting. However, pay attention to whether it is indicated on the gun inlet or on the nozzle. Big difference. If you say 10 cfm at the nozzle and set it to 10 when entering the gun, you will have problems. It will not have enough air pressure, which will result in the paint not being sprayed properly and an excessive amount of orange peel is sprayed.

Using my Iwata, I use an air regulator on the end of my gun. I set it between 18 and 24 psi. Air pressure will be different depending on the spray gun you have. For Iwata, 18-24 psi is usually ideal for most coatings. As mentioned above, too little air pressure will atomize the coating (orange peel), and too much air pressure will overspray, causing the excess spray to waste paint and cause the excess spray to land again. on the surface, which will make the paint run out. dry look.

2. Adjust the pattern

Adjusting the pattern will adjust the pattern from a small ball to a wide fan shape. If the pattern is not wide enough, you will have lines and streaks in your paint job. If the pattern is too wide, you may have poor coverage and waste paint supplies. With Iwata’s spray gun, I open the pattern fully open. Then I start to close the adjustment until I start to see the pattern start to get smaller. Once it gets to that point, I stop and make my next adjustment.

3. Fluid adjustment

This will depend on the type of product you have sprayed. For the clear coat, I open the setting all the way to allow a lot of liquid to come out. If I am firing the base coat, I will adjust and close the knob about 3-4 turns to allow less liquid to spray.

4. Fine adjustment

I have the weapon listed, but I have to adjust it to my techniques. First, the additional adjustments may have changed my air pressure, so I will readjust the psi if necessary. Next, I will spray a test pattern on our spray cart. If it runs or looks too thick, I’ll widen the pattern. If it does not cover well, I will reduce my pattern. Lastly, I will adjust the amount of liquid. If it feels too much, I’ll adjust it for less fluid, and if it doesn’t seem like enough fluid comes out, I’ll increase the fluid setting.

5. Practice

The last piece of advice I can give you is to practice. That’s what it takes and don’t be afraid to make adjustments. Make your spray gun suit your technique, rather than adjusting your technique to match the paint gun. The spray gun tips were intended for an Iwata spray gun, but any other paint gun you are using will follow the same steps.
