I'll try to get pics this weekend. Going to get some new 18 gauge sheet and wheel some shape and give it another go. Not sure what 06 wire converts to.. But the smallest I can find is .024.

0.024 is .06mm or close enough.

The weld looks like its to cold, not enough heat on amperage. Maybe you are touch welding with the MIG with the fear you may blow holes making your job bigger.
There are 2 ways I look at it, if you can't turn the heat up to get full penetration, then the parent metal is not thick enough or there is far to much contamination, corrosion or porosity. The other issue could be the wire speed is to fast, where the melted wire sits on top, again no penetration (that gives the same effect as not enough heat.
If your welding and the settings are good for the thickness of the material, don't be scared to keep blowing the parent away until you reach a good stock of material, then just keep adding more weld to the other side. A lot of guys do the touch and tap of the trigger (on and off in short bursts) in fear of blowing those holes, when in fact technique and settings will give good penetration.
I would practice on different materials so you can see whats going on, then it will click.

Mig welding is a cake walk as far as welding goes. I suggest you go down to your local body shop with an unpainted piece of metal and your welding mask and offer to pay the guy to teach you to mig weld. Within 10 to 15 minutes you should be good enough to practice further on your own. It’s great to learn tips, tricks and sources on the internet but hands on with a good welder present is the real way to learn welding IMO. ~ John Buchtenkirch
