Ok guys, I need some feedback. I’ve got a Crossfire Pro with an Everlast PowerPlasma 82i. I’ve been outsourcing my production parts to be laser cut, but I’m going to take a stab at plasma cutting them myself and CNC milling the features that need to be perfect. The 82i cuts pretty well, but I want to really push it to perfection and get the least bevel possible.
So here’s my main question:
To achieve the least amount of bevel possible, should I max it out at 85 amps and 75 psi air? Or should I turn it down and run a smaller nozzle? I’m going to spend some time fine-tuning, but I’m wondering what amperage range is the best place to focus my efforts. I’m not too worried about kerf width.
If I have to go with a Hypertherm 45 sync I’m open to this but really think I can get the quality I need with what I have.
I almost forgot to mention I’m cutting 1/4” A36 plate.
Best quality is normally a bit slower vs a bit faster.
Personally I’d try cuts in the 45 amp range and 60 amp range, and go from there.
You shouldn’t be getting beveling on 1/4” though, unless your Z axis assembly isn’t trammed, the cut speeds are too fast, have moisture present, and/or you’ve got cheap consumables.
Cut tons of 3/16” myself and my bevel will begin to appear if I’ve been doing a lot of programs back to back (heat = moisture) or if my consumables have lots of pierces on them.

Stick with your Everlast, fine tune it. Cut height is big contributor to bevel. On my crossfire pro I have a titan 45 plasma cutter and have it cutting almost as good as my Hypertherm powermax45 xp.

Agree with KwikFab and Richard. I have very little bevel and very little dross with 1/4” mild steel and I relate it mostly to the correct cut height, dry air and I make sure to change the nozzle as soon as I start seeing any bevel. That seems to be the consumable that wears more quickly.
I have the Hypertherm 45XP and only back off from the 45 amps when cutting 16 gauge with smaller features in the design.
