I need to make a prototype part for a customer out of stainless. I have cut stainless before, but looking for “best practices” with the use of only compressed air for prototype. If all goes well, I’ll look into F5…but not wanting to invest anything up front.
I see everything from speed up to slow down, increase power to decrease power…Any lessons learned aside from book settings for just a few parts, to minimize dross?
For reference, the part will be less than 5” diameter with some detail.
30 amps 88 ipm. All the other settings are the same as steel. That number is with my everlast 82i, So some adjustment may be required. For F5 gas, you will need to speed up a little due to the hydrogen in the gas mix.
It’s the same as steel. Stainless cuts great; it just sugar the edges. If you have excessive dross, speed it up a little. The F5 gas will keep the edges somewhat clean. I use 2 or 3 3000 scf F5 bottles with a hydrogen regulator on a dedicated 1-inch black pipe run to the back of the plasma cutter. I use a quick connection to connect it.
