I started welding back in 1963, ran a steel fabrication shop for equipment and so here's the way it goes-it takes time, don't get in a hurry, set up some scrap low-carbon steel on a work bench, set the gas flow by using as small amount as needed, a slight hiss when you pull the trigger, CO2 works great, and make sure no wind is blowing because it can blow the gas out of the nozzle, next on a small welder pick the highest temp range and by keeping one hand on the feed control, start welding and using the rheostat, run the wire speed up until it sounds like bacon frying, write down the settings for later use, and now set the welder on the next lower heat range they are A,B,C,D so do the same trick for feed control. It always tends to go better with a solid wire .025 for light stuff and .035 for heavier, but I doubt your welder would work well with the bigger diameter wire. The wire is sold with the diameter on the box or package. PRACTICE on scrap and then work on a small project, keep the nozzle clean, and the gaps as close, high temp will give more penetration, just welding on top does nothing to weld two pieces together, for a butt weld, grind both sides on a 45 degree angle so you are filling this "V" gap from bottom to top with weld. remember those little balls of melted steel rolling off the table always get in your shoe, so wear bluejeans and boots, gloves and a leather welding jacket, and if you can afford it a auto-dark helmet
