RE: Arc Spray investment help
All arc guns will spray the same kinds of coatings. A given amount of electrical current will melt a corresponding amount of wire. Changing air caps can change the spray pattern a little bit, but the basic mechanism of coating is always the same. That being said, the way to decide which system is best for you is to evaluate reliability, both of wire feeding and component wear.
A "pull-type" gun will give you uniform, reliable feeding. It may weigh a little more, but it very little. Guns are available with both electric and pneumatic motors. Get an electric motor. It will be more reliable. Lastly, look at the materials of construction of the gun. The parts should be made out of materials which can withstand the constant feeding of the wire and the associated heat.
Since everyone else is plugging their favorite system, I will recommend the ArcMaster 300 from UniqueCoat. It is a lightweight, pull-type gun with an electric drive made of high quality materials. It has adjustable drive rollers to allow the user to feed soft, hard, and cored wires.
