HF start.... Any way to change to LF?

[geezer]

I have been wrestling with HF interference on my PP256 and I have grounded everything very well, it wreaks havoc in my cnc equipment and has created alot of cost in trashed work pieces when this happens on mills including tooling breakage and crashes. I was wondering if there is a way to convert it over to low frequency to fix this or am i SOL?

Thanks in advance!

The solution for that is FERRITE CHOKES on your CNC equipment, the welder is not to blame, even a plasma torch will generate HF interference, check out this site: http://computer.howstuffworks.com/question352.htm for more info on how it works, Radio shack or someother outfit will have them, they just snap over the CNC cables and eliminate the HF problem.
