Machine settings for 3/8 plate

Postby chauto » Tue Jan 20, 2009 12:44 am

I am new to plasma cutting, Which tip size, Amp setting, cutting speed, air pressure ? I'm getting lots of slag and the cut looks poor. This is on 3/8 plate and Hypertherm 1000
Thanks for any help.

I am using 80 amp tip, set @75 amps 90 psi, inside cuts are CCW outside cuts are CW, I have tried 45 to 70 ipm and still getting lots of slag on bottom side of cut. Do you think a 60 amp tip would work better?

A 60 amp tip should help to reduce the slag since it will have a smaller orifice. Be sure to keep your amps at 60amps, no higher, and reduce your travel speed.

Hey guy just a question about cutting speed. You guy are saying to cut at 70ipm. I have been doing most of my cutting at anywhere from 2.0 to 3.0. Are we talking about the same thing?????? Also i didn't see any remarks about how to change the direction of the cut.

Thanks for all the info everyone, 60 amp tip @ 60 amps and 25-30 ipm, 90 psi works very well.
