He jammed the 6010 rod into the bevel, pushing it uphill against common sense. The key was the keyhole—that tiny, glowing gap at the leading edge of the puddle. Too big, and you blow through. Too small, and you lack penetration. Leo’s hand moved in a tight, rhythmic weave: two steps up, one step back.

He struck the arc again, this time changing his angle. Instead of pulling the rod, he pushed it slightly—a modified 5G technique few knew. The puddle flattened. The slag flowed behind like a wave.
