Are you using air or argon for stainless, argon is even cleaner with next to no cleanup. They do have special gas mixes for stainless but they aren’t cheap…
I found this little quote about f5 on the internet.
What is f5 plasma gas?
F5 (5% hydrogen 95% nitrogen) is used primarily for cutting stainless steel. F5 provides fast, oxide-free cuts, however the hydrogen gas introduces a lot of heat into the material.
The only reference I can find to argon being used with the plasma torch is with marking on the hypertherm 45xp.
The three gases that I can find hypertherm using and having cut charts for are
compressed air
nitrogen
f5 hydrogen nitrogen mix.
wonder what f5 is worth?
I’m going to check tomorrow at my local supplier.
With doing the 14 gauge according to their recommendations I wouldn’t be able to use the fine cut consumables and it’s smaller than the 1/4" recommended with using f5
Some shots of a straight off the table stainless business card.
No clean up at all.
Running dry compressed air at hypertherm 85 book settings.

You can see on the first pierce which is the f of fourthstate.ca there’s more of a divot.the delay was set for about 25% more before I could dial it back in fire control.
Richard, there’s a bunch here… They are on the Lightburn forum… I think it’s OK to go and grab them… You have to look through all of them, some are not useful…
