Re: O/T Welding question..avoiding the bird shEt welds
Your heat is probably too low. Splatter can be caused by insufficient shielding gas (not enough/oxidized weld), dirty material (mig requires a pretty squeaky clean area), too much wire (too fast) or too little heat (they go together). In mig welding you can 'hear' the right setting of heat and wire speed for the material. A proper setup will sound very tight and have a high-pitched buzz. What thickness of material did you have? Without pre-heat, IMHO 1/8" is the max you'll be able to weld with 0.30 wire and a 110 wire feed. If you preheat your starting point to cherry red before starting, you could go up a size. If you go to 0.35 wire, you can probably go up another thickness of metal (0.35 wire carries about 40% more current than 0.3 wire at the same setting).
Try this: Clean everthing very well (i.e. grind to shinny metal). Make sure you have an excellent groung point. Pick a power setting that seems right (again, 1/8 to 3/16 should be set at or very near the max with 0.30 wire), and then adjust your wire speed until it gets that high-pitched, very tight buzzing sound. The wire speed will probably need to be fairly fast as well. If you have a manual with the welder, it should give you some pointers on setup and welding. After welding a couple of inches, you should be able to stop and have the material glowing red pretty good. If not, you aint got enough current going into it. If I don't preheat what I am welding, I always hang around a second or two on my starting point before before weaving my way along.
