Does anyone have a good source for travel speeds for different material thickness and amp settings? I have a Hypertherm book that has low amp settings but nothing for the higher amps. I am trying to figure out what the differences will be between the different machines in a CNC setup.
please post if you fine I have look for the same thing, also the cutting heigth for torches.
have fun

This is what I have from Hypertherm. From the different charts it seems like the kind of torch has something to do with it, too. Mainly torch height, as their machine torch has a couple of different sets of consumables, shielded (drag), and unshielded. There are charts for aluminum and stainless as well, but again only for low amperage.Quote:

From these speeds I think I would rather use servo drives instead of steppers.
Hypertherm publishes the data in their user manuals, which appears to be where Rambozo got his chart:Quote:

Click on a machine and download the manual for the charts. These are obviously for the specific machine and consumables, but it is at least a start.
Thanks Rambozo for the charts
Question it states .200" pierce height and .080 cut height being new to CNC plasma I assume the controller starts at the pierce height and turns on the torch.
then starts moving down to the cut height and the pilot arc will ignites as it goes down. And has a delay to insure the plasma cut through the metal before moving.
Is this correct????

I think that is correct, I've been learning sheet cam, and I remember that being one of the settings. When I called Eagle Plasma to get help wiring my THC they told me they were cutting at .09 with a Lotos plasma cutter.
