Arc voltage question from Everlast 82i to THCAD-2

I have my machine running and everything with it seems to be running well. The one problem I have is the tips on the torch keep getting ruined and then the plasma arc seems to come out at different angles. I had thought maybe it was water in the air lines but I'm pretty confident that I have dried the air and it still happens. A 10 minute cut with a couple dozen pierces and I need to replace the cup. When the tip is new it cuts very straight and cleanly.

I have a 1.2 tip in the everlast 82i with it set to 45 amps and 80 IPM for 10 gauge steel. I have tried increasing the voltage more to the max rating for the tip but that didn't seem to change anything. I run the torch around .06 off the material with it on auto volts and it seems to keep that height pretty well with the THC. Wondering what I should focus on to get it tuned in. Is there anything out there in the way of a tuning guide for the THCAD? Thanks for any help.
 

I also have an 82i.  I have found that the stock Everlast torch is junk -- I also had the problem of consumables not lasting very long.  I switched over to two torches that are now my "go-to" torches -- they are the PE85C (shielded) and IPTM80 (non-shielded) from PowerEdge Cutter.  Consumables are a bit more expensive, but they last far longer than with the Everlast stock torch -- and if you get the retrofit kit, they have the advantage of being interchangeable; just mount the barrel on your Z-axis & screw in whichever torch you want to use.

Consumable life improved dramatically, even at 80-amps.  I run my torch at 6mm pierce height & 3.2mm cut height @ 100 volts on 1/2" mild steel plate with 1.2mm or 1.3mm tips. Speed is 450mm/ min.
