cut speed and slag

[moosehorn]

I have been cutting some 16 gauge cold rolled steel with my hypertherm 1000 at 150 inches /min
and seem to have more slag on the bottom side of the cut than I think I should.
I'm using a plasmacam 4x4 table, clean dry air, using all hypertherm cut charts for finecut.
I'm wondering should I slow the speed down,or speed up to get less slag?
I'm sure some of you professionals can help me out. thanks in advance moosehorn

More speed. Lower amperage setting.

Like these guys said, speed it up. I like to test by cutting a straight 24" lines and gradually increasing the speed with each line that I cut. Eventually you will go too fast and it will no longer cut through. This will help to find the optimum cut speed for minimal dross for a given material thickness and amperage combination.

great advice weldguy thank you!
