I have 2 test on pipe using flux core; root, hot pass, filler & cap. It is uphill. The spec's are for ABS standards. What is the procedure; ex. what land, gap, etc do i use? Also, what should the machine be set on? I'm used to welding with stick. I can weld with flux-core & mig, but never tested on the 6/gr. Any help would be appreciated. Thanks!
