Re: Powder not charging
Actually, until recently, I was doing multiple colors without preheating. On many parts, I will do a chrome coating and cure, then follow it up with a color, and wipe off the color powder to expose portions of the chrome, then cure. Then I would follow up the whole thing with a clear coat, all while the part is room temperature. I have one part that has five different colors, plus a clear.
I opened up the case for the power supply last night and found a little plastic box where all the wires were coming out of. I removed the cover from this, and found a loose circuit board (the screws had not been installed to anchor it down) and another plastic box with more wires coming out of it that was potted solid. I checked some of the components on the circuit board (diodes, small transformer, relay) and found them to be OK. The whole unit was made in China, so there is probably little chance to get it repaired.
I'm assuming it's something in the control box. When I first purchased the gun, the tip would jump a gap of almost 1/4" with a huge spark. Now it is more like a small static discharge from shuffling your feet on a carpet, just before the tip touches the part. Oh well.
Does anyone know what the specifications are on these hobby guns? What is the frequency and the voltage?
