- I do an experiment in this video to show everyone how important a GROUNDING ROD is for your POWDER COAT system, and answer the question, DO YOU NEED IT?

The power unit has the primary job of imparting a positive charge to the powder to enhance and encourage it to stick to the negative, grounded, part. Powder movement through the plastic of the gun develops a static charge that helps it stick. This is the entire basis for some of the systems out there. The static charge, coupled with the additional charge from the controller, allows for MORE powder to stick and stick better and more uniformly...ESPECIALLY if two or more coats are required. You are correct, without a strong ground, you cannot powder coat.
Thank you for watching and commenting.
I just stumbled onto this video. Super new to powder coating. Last night I went to do a test piece. When I finished my piece I went turn the machine off and noticed that I forgot to turn it on yet I had a very good coat. I guess my ground that I have been fretting over works. Thanks for your great videos.
Wonderful!
Surely in the second test when you disconnect the ground rod, if you had not touched the piece, the powder paint would not have adhered since we electrically present a potential to ground, that is the reason why you still managed to adhere the particles, Thanks for your explanatory video, from now on I will take grounding more seriously.
Thanks for watching!
yes good ground is key but the reason for your powder to stick when its turned off is that it works like a tribo system the powder get static charge when in runs thru the powder gun and rubs on the inside of it
Yes, that's true. Thanks for watching!
I wonder if you're getting some charge separation in the powder just from spraying. Static often builds up in clouds where there are particles rubbing against each other, so it seems possible that the charge is building up in the canister. IIRC 15kv (the rated voltage on the Eastwood gun) is not a very high potential when it comes to "static electricity", so self charging is a plausible explanation. ALSO, it may seem unimportant, but charge is negative. The power builds up a negative charge because electrons are added on. Ground is simply a low resistance path to lower potential. To make an analogy, the charge on the powder is like a bowling ball that is lifted to the top of a hill. A good ground is a cliff. A bad ground is like rolling the ball down a rocky side of the hill---it falls the same distance but with a lot of bouncing around and it takes a lot longer. You're fooling yourself by thinking that charge is positive and that ground can be strong. I have a grounding rod nearby but wouldn't the ground in most outlets work well, too? Low resistance ground is most important for very large currents, which is not the case here..
That is interesting. Air moving over a surface will produce a static charge, so the powder will have a charge imparted to it with or without the gun turned on, so if the part is grounded the powder will be attracted to it.
Sand blasting cabinets are a good example of that phenomenon. If you don't have them grounded they will shock the crap out of you due to static electricity build up from the blasting particals movement.
@@CycleFab I've see sparks in my sandblaster so that is for sure true. I used to know a guy who was an electrical engineer for a company that used industrial sized sand blasters in manufacturing and one of his duties was to make sure the equipment was all grounded correctly because apparently the charge that built up could shock the hell out of you...
I have the HF gun, your mods make it nebulize well. The HF powder adheres fine but other brands do not, at all. I do get a spark from my gun to the part. I guess I should soak the area of my ground rod. Trying to figure it all out.
It's a good idea to keep the ground wet around your grounding rod.
Thanks for the video! My question is do you put the ground clip that is on the machine onto the ground rod cable also? Grd rod to part clip from machine to grd rod? Keep up the good job 😊 mt.
Yes, I use both. The main/new ground rod for my primary ground and then clip the small ground wire from the PC machine to my parts hanger right beside the main ground wire.
@@CycleFab thanks bud for the info All new to me 👍
Do have to wet the ground rod with water before powder coating
Not necessarily, unless you live in a very dry climate or you haven't had rain in a few months. Thanks for watching.
I was wondering if I can hookup to my home electrical panel grounding rod. Any thoughts on that? Thanks for your videos!
Yes, absolutely!
Does the grounding rod in the ground and subsequent ground wire running to the hanging part eliminate the need for the ground wire and foot pedal that comes with the HF unit?
You'll need to always use the foot pedal with the HF and the hand button on the Eastwood powder coat systems. The independent grounding rod just greatly improves the function of any powder coating system. Thanks for watching and commenting.
Hi Larry, are you planning to restock your Eastwood diffuser kits on Ebay? I’d like to purchase one. Thanks!
Try clicking on the link again, should work this time.
Very interesting. One thing, wear PPE, I can see your booth but you really need gloves, eye protection and a respirator.
Yes, you are right
this one time I accidentally powdered a part in Prismatic Powders Illusion Blueberry without plugging the control box and hooking up the ground clamp beforehand, and to my surprise the powder stuck to the part perfectly, I didn't even realize the machine was unplugged and unclamped because it was working 100% normally and came out great
this is a two stage powder too, basecoat and clear coat so I was ultra shocked, usually the second coat/top coat has a harder time sticking since the part has already been cured in basecoat but it was stuck the same without the machine turned on, no more difficult than usual, can anyone exolain this please? Why did it work fully turned off? The powder didn't even fall off on the way to the oven and I was led to believe it would've fallen off due to the lack of static charge holding the charged powder particles to the part
keep in mind I just used regular 14ga steel wire as my grounding wire and didn't use a grounding rod directly to earth as he does in this video so I'm so confused
I have bought your cone and defused kit and I have a grounding rod planted in the ground but still am not getting any stick with the powder...is there something wrong with my ground it is connected to a jangling rod going through g my powder booth?
Thanks
