I need to cut some 3"x3"x3/16" mild steel angle this weekend and am looking for setting suggestions. I want to cut the angle in half along the 90 degree bend so I can use the pieces as flat stock to cover the ends (like a v tray). I have a PP205 and was thinking 30a and 60 psi....any other suggestions?
Why not just cut at 50 amps?
So the max amps would be best. I thought that the cut width (kerf?) is wider the higher the amps and there is more dross(?) at the bottom of the cut. I will have to get the cutting speed right also.
Here is some good reading that will explain about the two kinds of dross, upper and lower, the affect of cut height etc.: http://www.agelkom.com.tr/thc_vs_sensor.htmQuote:

And good dry air.Quote:

Have a good 4th of July weekend everyone!
