Remember a lot of that comes from the correct arc length. Once you find the correct arc length, and heat settings getting the stack of dimes will be easy.

Any advise on arc length? I have the arc force set on 0. I think about 15 deg rod angle.

That's something I'd have to show you in person! And I just don't have the words to describe it to you.
I have the best luck with Hobart's 335 A 6011, and ESAB's 10P 6010. How hot are you running? I like about 75-amps. If you run too hot, the ripples won't stand out. Imagine running a big spoon in a bowl of cake batter, and turning the batter over with the spoon. Try to get the molten metal to act like cake batter. :laughing:

I am running 3/32 rods at about 70-75 amps. Should I hold a fairly tight arc? I think I am holding the tip of the rod about 1/8 away from the piece. I am using air liquide brand 6011, they seem to run quite well. I will buy 6010 next time.

I don't hardly ever run 3/32 inch 60XX. I think you're way too hot! I think you need to be down around 45 to 50-amps. Yes 1/8-inch arc length sounds about right, but not being there to see the results, it's really hard to say.

Ok I will try it again with much less amperage. The box say 75 amp on it, but I think that is for ac, seeing as 75 amps on my tombstone ran them well.

Personally I think it's going to be hard to get the stack of dimes look with 3/32, or at least hard to see them anyway, or maybe that's just me.:laughing:

This is what you're shooting for.
