Is there a suggested Amp/Thickness chart or rule of thumb for plasma cutting? I have the LP-40D and often jump between many different material thicknesses. Most of the time I've been leaving it set pretty high. Unfortunately, I don't have a lot of time (or scrap for that matter) to try many different settings. With the higher settings (to high), I end up with a lot of clean-up afterwords.
Is there a basic chart kind of like the charts in most mig welders giving basic settings for different materials and thicknesses?
