So I've been told over an over to use the smallest consumables at the lowest amperage possible for the best cuts over and over.
I have a job that is 1/2 steel plate that needs to be deadly accurate. I usually use 65 amp stuff for that and it works fine. I tried 45 amp and that was no fun whatsoever. I figured what the hell, let's crank it up. 105 amps 141 volts, .7 second pierce delay, 60 inches per minute, corner speed is 85 percent of that. Machine is a Dynatorch xls 5x10.

Best cuts I've ever seen on 1/2 plate that was not high definition. Crank it up and let her eat!! Parts are dead nuts

Yes, I have heard that also and I believe it comes from the artistic community who are looking for thinnest the kerf width so they can get as much detail in as possible.

For parts like what your cutting I have had the same experience, higher amps and just sticking to the Hypertherm specs for best results. Its amazing what these air plasma's can do anymore!

Lowest amperage will give thinnest kerf and least taper. Or so that's what I've been told.
