Here was the best from what everyone posted.
kylesgorter - "I always set the voltage to the recomended setting for the thickness. With 0.023 I got a tad higher and with 0.035 the same or a tad lower. I go high on the WFS settings then start drawing a bead while turning the wfs down very slowly until i get the proper sound. Tuning by sound has always been the best for me. You want it to be a steady buzzing without popping, burnback, or sticking in the pool. You know you have it setup when it sounds like sizzling bacon and theres much less sparks and spatter. Rule of thumb, set the voltage first and tune the wfs to that. Every joint has its own setting that work best for it so experiment with different settings and joints and wire sizes and find what works best, also pushing or pulling the bead has a large affect on bead appearance, penetration etc. Be mindful of the feed angle as well as you do not want to compromise gas sheilding or flow and you want the heat directed into the joint. Always remeber dont keep up with the welder, set up the machine properly so that it keeps up with you.
Dont mess with weave patterns or "circles" or anything. getting your speed control and puddle control down first is most important. Draw straight stinger beads and watch the puddle. once you have mastered your speed control and can control the puddle's shape and thickness you can move on to a whip or zig zag technique. Ive found those to be all thats needed for 95% of joints.
I will say that the quality and appearance of your welding will always depend first and foremost on the joint prep and quality of the fit-up. Proper spacing, tacking, beveling etc is required to get the rest of it right. Some joints need more beveling where as others like corner joints with slightly thicker plate are better without any beveling on the outer shoulder but benefit from beveling in the root of the joint before fitup. Knowing these things is very important and you will not get better without practice.
I like running a smaller wire 0.023 for a lot for the work I do with a higher voltage. I use er70s-6 wire which is pretty standard but some shops supply others so its good to know the differences. You want the edges of your weld to "wet out" so that they look to be burned into the base material while at the same time having no real shoulder or undercut. The quality of your weld and its appearance come a lot from getting tha edge to look right. ive found if Im doing weverything right and the edges and machine are correct everything else is in spec as well."
As for tip angle, I had it pointed straight at the joint. This is what I still want to practice with. The other guys say that I can improve my start and finish by changing the angle some.
Also, I usually get my metal from Patton's but it's out in San Bernardino. I don't know where you would want to get it from. Usually these places have a scrap bin and you can get the scrap for cheaper. That's how I got the square tubing that I used on the Explorer.
