after i figured out the correct torch height it cut really well. (keep in mind i don't have auto height control) at first i had it set at .120, then had to move it up to around .200 to get the slag to stop sticking to the tip and messing up the tip and cut. i thought moving it up that high would give me a badly angled cut but after seeing the results, it looks like it was made to cut that high. i've been trying the keep the cut height around .090-.100 for everything but i think i can start moving it up now as occasionally a part get warped while cutting and gets to close or actualy drags.

oh ya, the alumunum is 3/16'' thick and i hit it with the DA sander after the cut. it will fit the center line of the tubes when done, the outside still needs to be trimmed. i mis-measured a bit.

Great looking cut. I've been cutting around .062 but will try the 200. I also have my pierce height set to .250 now then ramp down to cut height.

i was probably just getting slag on the pierce and it stuck on during the cut making it mess the tip up. have you had any problems cutting that close?

Looks great. I started at.030 and then went up from there. I am running about.125 now.

I have occasionally scratched my aluminum plate with slag that stuck on the torch. I raised the torch to .200 today on a steel plate cut and it worked fine. (.250 pierce height)
