I did some experiments today with E6011, E6013 and E7018AC with my AC welder that has taps for 40, 50, 75 & 100A taps.
At 75A, AC- 3/32 E6011 has a lot of spatter, but seems to penetrate quite nicely.
At 75A, AC- 3/32 E6013 welds quite nicely.
At 100A, AC- 3/32 E6013 was welding fantastic.
At 100A, AC- 3/32 E7018 did beautiful welds, but I couldn’t keep the arc going and the longest bead was maybe 1.5”.
So today, with my AC welder, my favourite rod is E6013.
Here’s my experiments:
And now I’ve selected my “favourite” rod, I’m just running beads to practise:
