well for what is worth, myself and I have 2 other welders working for me and they are seasoned also, I currently run 2 Lincoln 250 gas powered welders, one runs a Lincoln LN25 suitcase mig welder, the other we stick with, one man runs the mig the other runs the stick, when welding with the stick we always weld uphill , JD is correct, when welding with a stick downhill you will have flux running into the weld, and In my experience and my other two welders this is how we weld with stick and mostly use 7018 on mild steel, now with the mig welder or suitcase that bugger has to run hot, soooooo, we weld down hill with it, using 035 wire non flux with 75/25 mix, the reason we run down hill you can keep up with your weld, running uphill makes to much puddle and tends to run, Now what I have found over the years ( this works for us ), we leave a little crack when butting two piece together so you can stick the rod in the crack also and get good penetration now after you weld uphill it will look like crap until you knock the flux off, it tends to run down and puddle, and for the guys that say you cannot weld uphill, do not beat yourself up, You can do it,, Play with your heat, and practice, just like welding over head, play with your heat settings when welding over head your heat has to be lower than flat weld, hope this helps
