Grounding your Redline Powder Coating Gun Correctly
One of the most common mistakes we see made by powder coaters is not grounding their guns correctly so in todays video, we’ll be talking about some specific best practices for you to follow with your Redline powder coating gun.
Failure to ground any powder coating gun properly can result in serious personal injury, gun failure and a whole host of finishing issues so it’s extremely important to get this right.
Alright that said… Let’s first take a quick look at how hand-held powder guns like the Redline EZ50 work to better understand why the way you ground them is so important and then we’ll show you the best way to set up you’re system.
The majority of hand held guns powder coat guns typically have two grounds... one to clip to the part being coated and a second- internal ground that protects the person holding the gun.
Both of these ground are wired to the power plug on the unit and use the wiring in your home or business to connect to an earth ground.
While this is a functional way of grounding the gun and part, using just the ground circuit with your electrical system is not recommended and will definitely impact your finishing results.
Some of the problems associated with shared grounds are uneven powder layers, poor powder transfer efficiency, powder that won’t stick to the part and Faraday cages.
For best results we recommend driving an 8 or 10 foot long solid copper grounding rod at least six feet into the ground as close to the location of the booth and gun as possible. Here we’ve gone right through the floor next to the test booth in our shop.
Next…Connect the grounding clip coming from your Redline powder coating gun directly to that rod making sure there is a clean- tight connection.
Then using a piece of 12 gauge or thicker wire and two squeeze clips, attach one end of the wire to ground rod and the other to part hanger, holder or cart.
This setup will give you the optimum conditions for maximum powder transfer, smooth laydown of the powder and less interference from Faraday cages.
Just be sure to periodically clean the grounding clip, and parts hanger to maintain that good ground.
So that’s it, just a few simple rules to follow to keep you safe and get the best finishing results.
