Hi lads, I'm new here and new to welding. Here's a photo of a flux core mig weld I've done, I want your advice on it cos it's a sh*t weld and Idk what I'm doing wrong. There's a parameter guide with the welder for wire speed and voltage for what thickness you're welding. The weld looks like its just sitting on top of the Steel getting no penetration, any thoughts? Thanks
