A beginner MIG quandary ... I'm welding a patch on the chassis and I can't seem to run a decent bead. But when I run one on my test piece it's fine.
At first I thought I had the settings wrong - as when I set it up last time the power and particularly the wire speed were much lower than I'd have thought. But if I turn it up I blow through - and it's putting a good bead with penetration on my test pieces.
The metal is clean, I've cleaned for the earth. It is in an awkward spot where I can't get comfy and can't get in position to properly see the weld pool ... I accept I'm a carp welder - but am I missing anything obvious ?
