Maybe its because I'm using 3/32 tungsten and only have 1/16 aluminum fill rod left. I'm starting to think my fill rod is just too small for the welds I'm doing. Maybe with 3/32 or 1/8 fill rod I would get more definition I. My ridges...
Also DCEP gives more cleaning while DCEN gives more penetration right?
For Everlast, % is DCEP. Bead look is from your technique. Also with only 1/16" filler , that won't chill the puddle down much so you might not get much by way of freeze lines. Automated TIG will have totally smooth beads, as well because there is a constant feed of wire, not dipping. The welds are still just as strong. For things that get polished I will often use a small wire fed constantly to make smooth welds that polish easily. With thicker wire you would get more texture. Whether that is a good thing or not is up to you.
Yes, DCEP gives more cleaning, and DCEN giver more penetration.
