Anyone have suggestions with settings for .5" manganese? I am using a 1650 and have tried 60, 80 and 100 amp parts. The best so far is 80a @24ipm and 146v. Piercing is the big problem, delay is at 1.75sec. and pierce height is up to .28". If the machine moves before it gets through it is ugly, it will toast a shield and nozzle in a micro second. Stuff stinks too, very very smoky.
This material is non magnetic too. I have 799 pierces to make doing 1.125" holes.
Thanks,
