You may want to read this post. There is some cut charts in there. But they most likely won’t help as you have a plasma cutter rated at 45 amp with a 80 amp torch and the smallest cutting tip you can get is a 1.0mm/50 amp that has a .040" orifice hole.
What I would recommend is getting a IPT60 hand or a IPTM60 machine torch and wire it for your plasma cutter. That way you can get different size cutting tips so a cut chart would help get you in the ball park.
