Thin steel with gasless wire

[SiPMerlin150]

Hello fella's, heres my first proper attempt at using gasless wire 0.8 on 1.6mm sheet steel. I set up 2 pieces as a flat butt weld, however I welded it in a flat vertical position (If you know what I mean.)

I was mainly testing out a new wire against the stuff I used previously.
I think it turned out rather well. The penentration looks good. Just need a little more practice. I use a gas mig in work now and then to patch holes up in car sills to get them through an mot.

The last picture is the weld ground off.
