Also be comfortable before starting arc, no wt on arms, you want to be able to cover weld area while not moving, that helpsInstead of loops which can put Flux into weld.
Let's say 1/8 thick steel, get it clean, good ground. Try pulling the weld, and going up and down while push/pull to maintain distance, of wire from part being welded
Example: right handed weld left to right, have torch tilted slightly to the right so you can see puddle, start arc in valley and then move up,down say 3/16 inch, maintain distance, you want to push into the v and back out to go up and down, watch weld puddle.
Hope that helps, also you want wire feed fast enough so it sounds like bacon frying
Good start, Just remember to slow down if you think you are going too slow that's probably how fast you should be going. If the welds still look bad try going even slower, and always remember nice "cursive e's" or loops. Took me about 4-6 hours with a flux core mig to learn welding, keep it up!
