Please advise what instrument that is to check ground. You don't think a high priced "Megger" is required? The industry "rule of thumb" is less than 1 MegOHM
I was setting up yesterday, and I ran a cable from a water inlet pipe that went down into the stone floor, back to my small booth. And then I connected that cable and the gun (redline ez) ground connection to the object being coated…… does that sound correct?
I maybe thick as two planks. Please someone explain the science behind powder coating and the need for grounding. Why? What happens in theory? Please someone explain. All I know is the spray gun charges the paint with a positive ion.....one extra electron that's trying to escape........ And......?
Looks a lot like this one I found pittsburghsprayequip.com/products/wagner-grounding-tester?gclid=CjwKCAjwjdOIBhA_EiwAHz8xmwMtHkL3NdwKQpObrfmf20_5PdY2LFl4rRomlunczBTJLSY3tz3FEhoCWywQAvD_BwE
Rethink this as 1 electrical circuit, the powdercoat gun ground goes to the part, the charged paint is attracted to the ground. Your hook, booth, electric panel should provide the part with a good connection to the gun ground.
That ground is really meant to be a backup for the kool koat in case the electric plug has a bad ground . So ideally yes you will have a separate ground that you use to ground your product your coating and use the Koolcoat ground as a backup ground for the Koolkoat itself
