I am going to share some quick advice for starting off with a new powder coating gun. Whatever you do, get a less expensive gun for the first time. Beginner guns are priced at just under $200.
I think they are ideal because you know that they are made with a beginner in mind. Also, you do not have to invest a whole lot at the start only to find that powder coating is not exactly for you and your level of auto painting. There are lots of other pieces of equipment and supplies that you need to do powder coating so it is better to start off spending the least amount you can and go from there. Beginner guns are also made with a decent quality, so you will certainly get good results from using them. It is just that you don’t have to worry about buying something that is not going to get the job done.
Most inexpensive guns do have one drawback. At least, in my opinion, it is a drawback. They usually only offer you one preselected KV. With pricier guns you get a selection of kilovolts to choose from. Still, I say start off with a beginner gun and go from there.
