Not sure what it is but something isn't right --- way too much splatter... and not much HAZ (heat affected zone).
What gas are you using? Should be 75/25 Co2/Argon
18cfm is high for what you're welding... 15cfm should be plenty.
What wire are you using? What size?
I downloaded and read the MIG 200 owners manual.... Sorry.... after reading that I know why I own Miller equipment.
The settings on this machine do not correspond to settings on a Miller or a Lincoln... that whole 5-1 etc is just - Well I'll leave it at that.
I'd use the 1/8" settings... and you're right - in one place they recommend 5 and in another they say 6... I'd use the HIGHER range.
