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

[Tacoma747]

I had issues on my CNC table frying boards because the ESAB unit I have is hi-frequency start, I was talking to Oleg on the phone and he said the 60C will not fry boards or cause interference issues. A rep for another company is claiming otherwise (here: http://www.plasmaspider.com/viewtopic.php?f=3&t=6549 ), not saying he is right or wrong, BUT I don't want to have the same issues with the 60C, I bought one yesterday, and it should arrive next friday. I liked the idea of the 60C as it was designed for CNC systems, just wondering if I should have bought the PowerPlasma 50 instead since it is non-HF start.

Any precautions I should take when hooking it up? Is it safe to run the plasma torch lead and the drive motor cables in the same tracking?

Thanks!

thats why i bought the PowerPlasma 50 for the cnc reason love the machine works so good and come with the cnc plug on the machine and switch's 50 is more than you will ever need on a plasma table The HF Contact type uses a high-frequency, high-voltage spark to ionize the air through the torch head and initiate an arc. These require the torch to be in contact with the job material when starting, and so are not suitable for applications involving computer numerical controlled (CNC) cutting.

The Pilot Arc type uses a two cycle approach to producing plasma, avoiding the need for initial contact. First, a high-voltage, low current circuit is used to initialize a very small high-intensity spark within the torch body, thereby generating a small pocket of plasma gas. This is referred to as the pilot arc. The pilot arc has a return electrical path built into the torch head. The pilot arc will maintain itself until it is brought into proximity of the workpiece where it ignites the main plasma cutting arc. Plasma arcs are extremely hot and are in the range of 25,000 °C (45,000 °F).[1]

I guess my hope is, that if they advertise it to work with a CNC machine without issue, then my hope is that it will work as intended.

Seems I read somewhere they have a 30-day guarantee? I guess if it fries a board before 30 days I may send it back and get the 50.

I would go with the power ultra 250p nice unit then you have a stick welder and dc tig to boot and comes with a s45 torch head that works good with a plasma table plus has a cnc connector on back of unit . was thinking mite ask tech support if there is a way to make your 60 a pilot ark with a s45 torch also found a article were this guy got a hf to work http://www.cnczone.com/forums/cnc_pl...pilot_arc.html another article this guy has the torch come down and touch metal then raises before cutting with hf plasma http://www.super-tech.com/root/grp.asp?p1=assoc-jaan it makes sense to me check out bobcad also been playing with it cool program . they have a free test software at there site

I was thinking it was blow back start, but this is what the website says.

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.

blowback start and pilot arc are the same here is some more information on a 50p https://docs.google.com/viewer?a=v&q...e6IrzESvq8C7OQ
