Hi Jim, I recently ungraded to a Duramax machine torch on my 1250 powermax G3 and have asked you about the cut charts in the past. Still can't get up to recommended speeds in the charts. My new comsumables came in Fine Cut and 45 amp nozzles, replaced everything with new FC nozzle and electrode, and still to get a nice square edge, dross free cut I have to run around 110 ipm on 14 ga. mild steel, cut height .06 , pierce at .120 - .150 . If I run the 220 ipm it doesn't cut thru completely in spots it might leave a inch or so then cut thru again ? Just wondering if I'm missing something or if you could recommend something to try. Not a big problem, I just cut art work and a lot of detailed stuff so I have the time :>)
Thanks for all your time and help..............Ray
