Learn How to Cut the Best Holes with an Air Plasma on a CNC Cutting Table with Jim Colt

[@fernandofigueiredo8417]

He forgot to mention the most important requirement needed…. Cool, dry air! Without that, all other efforts will be lost

good explanation...thanks

Can you suggest ampere required for 16mm mild steel piercing

[@madensuyu3135]

130amp

[@fernandofigueiredo8417]

16mm is the equivalent to 5/8” here in the states. I cut that with 105 amps using a Hypertherm 105. It’ll cut up to 1-1/4” thick steel (30mm)

Thanks for the explanation, pretty useful.

HyperTherm is kinda ass. Air plasma is on the account of the electrode.
I've ran a Hypermax 105 for years, then went to a Kjellberg and everything is on the millimtere for once.
