Did you use any pulse or raw power?

Just straight power for the Aluminum on Advance Square Wave no pulse, 35% clean, AC Frequency 250 Hz, 100% Argon @ 28 CFH and 2% Lanthanated 1/8. Steel no pulse, 100% Argon @ 12 CFH and 2% Lanthanated 1/8 also. I like the preset Memory Program just switch to the number I have set for steel and weld or just got to the aluminum number preset and go. I wish they had more memory number, I set them close to what I like and adjust after take a little more time but it is still faster then my 250EX. I still like my 250EX I put the smaller torch on it so I don't have to keep change Tig guns.
