Machine settings for 3/8 plate

[chauto]

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.

Kslon, inches per minute, Also you can read about cutting directions under the posts poor cut quality there is very good info there.

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