Trying my hand at thicker steel to try learn, after having trouble with the thinner stiff. Not sure my setup is right though. Got a Clarke 151En, set to the highest setting (0.6 wire). However, everything I read says I need to get a "bacon sizzling like sound". I'm just getting a hum. Had trouble getting s puddle started, but think I managed it for one run. No sizzle, just wiggled it back and forth in a line, about as fast as I see in videos etc, with the recommended settings for 3-4mm steel with 0.6 wire: Pic: Don't seem to be getting much penetration, just seems to pile metal on the surface?
