Hi, Tommy
Im thinking of building very budget cnc plasma for diy hobby stuff. Very valuable information in your post and as you reposted there is really a confusion about pilot arc etc.
I have a budget plasma cutter i bet its HF because every cheap one is HF - I have upgraded it to have a Pilot Arc. So my question is - will a HF plasma cutter produce less interferences with pilot arc vs touch start or it will be the same?
Thanks again for the information you shared.
