Centroid Community CNC Support Forum

I have a Cut 60 with the machine torch that uses hypertherm consumables. Is there a plasma cutter profile set available that would work for the Acorn THC? I was told to use hypertherm 45 cut settings by the folks at Primeweld (there were no instructions with the new torch), the acorn manual says to use hypertherm 65. Someone’s else suggested to use hypertherm 45+primeweld cut 60 then divide by 2.

Ideally, Acorn has figured this out for me already. Fingers crossed

Hypertherm 45xp profiles are the best starting point for the Primeweld 60

Are you looking for voltage setting cut, speed or all of the above?
I'm just getting started with the Centroid system but Ive been in the industry for nearly 30 years. Hypertherm, Burny/Kaliburn, Victor, Linatrol etc. Im not familiar with the Primeweld system. But BTW Ive noticed some of these small import units use a high frequency start circuit to rival any of the old industrial systems or the Victor which is very hot. This HF noise can wreak havoc if you do not take proper precautions. Be sure you have a good ground rod shielded cables and I would add shielding to the torch leads and drain to ground as well. They come with no shield or the ones I saw. Invest in steel or Copper braided tube if you have one of these. If you have a blowback electrode system like hypertherm powermax, disregard.
As far as cut setting Id so some test cuts if you dont have a cut chart.
Turn off the THC. Find you ideal cut speed at correct cutting height. Record the Voltage reading at 100% speed. Be sure its not slowing for a corner. Add your speed and voltage to the Profile Database. Always keep these the same. If you slow the speed you will need to raise the voltage setting as the resistance changes as does the voltage reading between the electrod and work. You can usually get by slowing somewhere between 5 and 10% before causeing problems. But as you slow down the torch will get closer to the plate.

Also if the Centroid THC does sampling. You can find your volage setting in that manner. If not they may want to add the option. Basically setting the
at cut heght after pierce, locking/disabling the THC and reading/sampling the voltage at 100% cut speed. Same idea just just letting the system do it for you.

The plasma software already does this, it's called "smart sense". Smart sense will read the torch voltage when the cut has started and the THC delay has ended.

Yes, I was thinking it did. He can turn that on in the program manager, right?

Yes, the Profile Manager.
