Torch delay / torch height?

Hello People. 
I have two issues first; I have my 4'x4' CNC table using a Primeweld plasma machine along with a machine torch. I used sheetcam for my post-processor. My issue is when I start a cut job my machine starts to run before the torch fires up. quick on my feet i came up with a temporary workaround for me to finish up my job.  I increase the lead-in for my outside cuts, but this still is causing an issue with cutting holes. Can someone point me in the right direction?  I'm sure it's something small that I am missing. 
My second issue is torch height. I was running the "CNC preferred shielded consumables" see attached image,  on my table but I not getting as much of a straight cut as you can with plasma cutting. from the machine instructions and linuxcnc, it is telling me to lower my cut heigh, but I can't lower it anymore, physics is preventing that from happing, torch tip hits material I switch to unshielded consumables and raised my cut height as best I can to not hit the material. it cuts almost perfectly, with a couple more minor tweaks I will get there, my question is keep using unshielded, it's not going to hurt anything, is it?  
thanks again for your help. 
 shield consumables on the right / unshielded on the left 

 

sounds like you are using the wrong post processor.

here is a screenshot of the machine options

I will upload the backup and the info in about 6 hours. thank you Tommylight
