Everlast 50S cut chart

I’m new to all of this… plasma’s, and cnc tables. I have been sending my cuts out to a larger shop. I just purchased a 50s but am now thinking I should have went with a 60s.

I saw a poster here cut 1/2" steel, is 1/2" aluminum doable? How about 1/2" stainless. I know slowing the machine down will help, but where is the cutoff at?

Everlast list the maximum Pierce at 3/8", how are you managing the Pierce in 1/2"?

1/2" would be the largest I work with, and typically the cuts would be small, say 20" long, and only occasionally at that. I will definitely be doing more 1/4" and under.

What do you guys think? Should I keep the 50s or go to the 60s?
