So I see a lot of issues on the forums with arc voltage, cut interrupts, bad usb, noise interference etc.
Here is my question.
Most tables I have seen on the industrial scale have a dedicated ground rod for the table for noise and EMF, why wouldn’t this resolve a lot of issues people are having with the Crossfire Pro system?
Yes you are right and it would help. But the reason you see it on big industrial tables is they are high frequency plasma cutting units.
I tried it once. I already had the rod in the ground near the table for other reasons but when I hooked it up I could no longer read arc voltage. I never found out why so never hooked it back up, it was more experimental then trying to fix a specific reason.
Tried this on my OG Crossfire. Didn’t help. My issues with that unit was fixed with a filter on the USB.
Still have the Ground wire laying under the PRO not hooked up.
I was having intermittent piercing problems, molten metal ending up on my shield and spraying sparks and molten metal at me, got burned a few times, but I weld and operate the table in flip flops when it’s hot so that expectedly happened.
After chasing this problem for quite a while getting bigger air lines and reducing my pressure delta, raising pierce delay, upping amperage…etc. I finally grounded my table with about $1 worth of wire and connectors and my issue has been totally solved.
Consumables are lasting 3x as long and cutting holes are perfect for what is expected from a plasma cut. It’s upped production because I don’t have to pause cuts to clear slag off the shield after piercings and is a huge weight off my shoulders. Lowered the cost of consumables 3 fold. I’m stoked!
Table is on a wood floor in a shipping container, not sure why it was needed, but onward and upward. Hope this helps someone.
Thank you for sharing this post. Would you be willing to share a little more detail…perhaps a photo or two?
I can verbally describe it pretty well for ya. So the metal shipping container is grounded with 2 ground rods and bare copper wire. I ran a piece of 12ga or 14ga copper wire (out of a wire scrap pile I have) from one of the self tappers holding the leg gussets on the table. The wire is run to another self tapper running through the wall of the container. I just used normal crimp on wire ends that fit the self tappers size. I also used copper wire dialytic grease on all connections for corrosion resistance.
If you have a cement foundation traditional shop you’d just have to run a wire from the table to the ground rods for the electrical service, or pound another rod in the ground dedicated to the table.
Ohhhhh! So now the $1 worth of stuff involves me buying a shipping container!!!??? 
I am just having fun with you. Good explanation. Thanks.
I can hardly CONTAIN my laughter… haha
You need to make sure that if you’re driving a new Ground rod. That the new rod is at least 6’ away from an existing ground rod. (it’s code plus it can cause all the grounds to be less effective.)
The shipping container is optional
