is there a list or a rough idea of what to set the speed to cut for the size of material we are cutting? I know each plasma machine is diff but a rough idea would help me alot, i am cutting 1/4 and the factory speed (1600) is way to fast ---

For 1/4” mild steel I would start here. ```auto 45 amps .08” torch cut height .2” pierce height .5 sec pierce delay 60”/min cut speed ``` ---

What amperage are you wanting to cut at? You can cut 1/4 mild steel anywhere from 40-100 amps. For the best cut I like to run the lowest amperage and slowest speed possible. For 1/4” I generally cut @ 40 amps - 45-50 ipm. .062 cut height about 1 second pierce delay ( depending on machine and nozzle size I usually set air pressure from 80-90 psi ) ---

Just google plasma cnc setup chart for your specific brand and model of cutter, you will get a bunch of charts- if theres not one for your machine you can use a close comparison machine… 😀 ---
