Will the PowerPlasma 60C cause hi-frequency interference on a CNC table?

I know it will work with CNC, I just want to know if I need to take any special precautions, I already have a ground rod for the control box, plasma cutter itself, and for the plasma table grating. Will I need to do anything further? I want to hear an answer from someone with Everlast, that way if something fries, I will have done everything I needed to do to prevent it. I could have done more with the ESAB to prevent the issues, but I was never impressed with the cut quality of the ESAB, which is why I just decided to buy something new. Thanks for the info everyone, I am really looking forward to trying out this unit.

The 60C does work fine with CNC and does not cause the interference that an HF start does contrary to the biased and innacurate report of Jim. Torchmate used it in that video without precautions. It's been tested at length. The start does not produce the noise or interference of HF. It's a faster start as well, over the blowback.

only thing i see in all the articles on the internet they recommend keeping the plasma cutter not close to the plasma table is that true - Mark is that true this place is in California cool place to get cable shielding wrap and protector sleeves for cnc wires http://www.zippertubing.com/?gclid=C...FQRgTAodLDDFMw

For HF yes.

Sounds good. Believe me, if it works great I'll be posting in the thread on plasmaspider to say so. On the Everlast it says it is a HF machine, you say it does not produce interference, I am just going to assume it is a different style HF type that has been designed differently to not cause problems or something.

I do not have ferrite chokes on the motor cables, do I need them?
The way I have my computer/plasma/table setup, and with only a 25' lead on the torch, the torch basically sits underneath the computer (about 4' over and 4' under computer). Will this be a problem? I plan to eventually build an enclosure for the computer to help keep it 'clean'.

Thank you!

I don't see HF listed in the description... Source: http://www.everlastgenerators.com/Po...0C-366-pd.html

Features & Benefits
- High Voltage/Inductor Start is excellent choice for CNC operation with the fastest pierce times. This is different than HF starting as the frequency is lower, reducing the risk of interference associated with typical HF/HV starts.

I see that one... it needs to be fixed.

YES,,,you do need ferrite chokes,,,they are on just about every computor and TV device you buy,,,a simple cheap prevention device that wraps around the cables,,,try relocating the computor or control box further away from the torch head,,,,building a farraday cage as you refer to is another help,,,I can see no valid reason your Esab cutter won't work if you take the time to fix the layout of the units...and protect the cables..

Be sure to put the chokes at the cable ends.

I think I have the ESAB sold (pending payment from buyer), so that's a good thing...

Thanks for the info everyone, where it stated that it was a HF machine was what was throwing me off, and probably Jim from Hypertherm too.

you can get the chokes on ebay cheap , i run chokes on most my machine shop machines
