On a fillet weld on 14 ga steel, the bead should be about an 1/8" wide (.125"), so you are fine.

Your amperage should be set at 100 amps.

0.074" = 74 amps + 30% (25 amps) = ~99 amps.

If you can't get the bead to flow at 100 amps then you are too far from the metal.

I'm running at Lincoln Invertec205T set @ 78 amps and using a foot pedal, 3/32 Lanthanated, and .035 rod.
