Oh dear. Here's a tip - make sure you can see your weld through the mask. Then, without welding, practice moving the torch along the joint (without weaving), with the torch pointing towards the direction of travel at about oh I dunno now, 15 degrees to perpendicular, at a rate of around 5 seconds an inch.
If you're accurate with the torch at the joint, your metal is clean you should produce something like a toothpaste bead.
Too many amps, or more amps creats a flatter bead, too less amps a fatter one.
Don't wave the thing around unless you're filling a gap.
Someone else may have better tips, but these are mine.
way better than before so definitely moving in the right direction
constructive comments would be
I would have preferred to have seen all evidence of the earlier attempts to have been ground away before the second attempt
the new welds do look like a series of large tacks rather than single welds but practice moving along the joint whilst welding as minimutly suggests and things will improve further
get yourself a bit of material the same size as you are welding and play around with settings until you get that crackling bacon sound,
once you have the machine dialed in, start practising doings runs with your torch instead of multiple tacks, this will get you on the right road and you will find
it will become second nature on what settings to use on what material thickness. it's a steep learning curve when you start but it does get easier and mig is one
of the easiest to pic up.
