Where do I find my post processor

I work for a university and they just gave me a new computer. They put sheetcam on it but when I went to set it up, the plasma CNC machine we have is not on the post processor drop down menu. I also cannot find a downloadable post processor for it on the internet.

Our machine is Victor Cutmaster A60

The only cutmaster post processor that is preloaded to sheet cam has torch on and off as M03/M05 but the old computer would output the g-code having M07/M08

You can edit the post processor and change the m03/m05 to m07/m08.
