I saw a Hypertherm Hy Def plasma cut through 1" plate once, looked a lot like that, with a slight touch of bevel.
So you are saying your friends track burner is a POS and still cut that smooth?

No my plasma machine was the POS. The edge going up in the second and third pic was just a cut made by his A/O track burner. He has some real nice cuts on some of the scrap he gave me. His nice cut pieces was used on things he builds. I just did not want you to think that was plasma cut. I could get it to look way uglier with my plasma, if I don't have the parameters just right.

I have a TD 151 also, and it cut this on the first try. I'm happy enough with it that I would do it again...
I'm not real happy with the back side of the holes though...

Looks really good to me!!! What was your pierce height/ pierce dwell time/ cut height on the holes?? Also the type of tip/nozzle combo??

It was a while ago but I think these were the settings...

Pierce height and cut height was .130
pierce dwell was 1.5 seconds

and I was using a 100 Amp tip and the standard nozzle.

I stuck a square on it and it's not quite as square as yours it looks like though...
What was your settings?

Standard exposed 90/100 amp tip ( slightly used) Mine was a edge cut so I did not have a much pierce delay. (1 sec) 100 amps .200 Pierce height/ .190 cut height. 15 ipm. 70 lbs. air pressure while flowing. Different nozzles cut at at different speeds. I had good luck at 12 ipm. on another cut using another nozzle. I need to try a brand new eletrode and nozzle to see if it can improve. It's fine by me at this point.

hypertherm 1650's will cut trough 1" of metal and do a pretty nice job not on holes though, oxyfuel is the way to go on anything 1" and thicker as its cheaper just as fast and will get you nicer holes

There are many three phase plasma machines that will cut as well or better. It's hard to find any 100 amp single phase machines that can work like the Thermal. Esab has one out but it's not for sale yet. It will have a blow-back torch too.

It's hard to tell exactly how good that cut is from that angle (especially the holes). Also, running at that speed is like watching grass grow and a lot slower than oxy-fuel.

Nice cuts though.
