ah ok, I was unaware of the gap as I have seen it should be a tight joint at first to tack without filler, but it makes sense it would be better filled open with wire than having to burn through.Focus on one joint, probably the t fillet until it’s right, don’t bounce between them all. Your butt joint wants about a 1.6mm root gap to start seeing penetrstion
Good shout on the single joint, saves bouncing all over the shop and everything turning out pants.
