This is a copy and paste from another site (not my information but was helpful to me);

Under the heading Best rods for A.C. stick;

"6011 if you really need to penetrate deep in heavier material and apperance doesn't need to be super smooth. The bead can be fairly rough depending on your manipulation technique, there is more spatter than with 6013 and 7014, and it can tend to give more problems with sticking to the workpiece. This is a great all position rod for vertical up and overhead and works well with a "whip and pause" manipulation. Pause to melt in an deposit metal, whip forward and away a bit to allow the puddle to chill, repeat. On the root pass you see the keyhole form thru to the backside, then whip forward to let it cool and not burn the keyhole too large, then come back in to deposit metal and open the keyhole again. Slag removal can be a pain."

So the point is, you might have better results with a proper DC rod. I'll hope for the real welders on this site to chime in.

Your driveway scraper looks neat! How about a before and after after picture of driveway? Just curious how well it worked!

This might be a Spring project. I have a lot of weeds in the driveway and I need more gravel. We'll see, if the weather cooperates I might try it out.

The 6011 rod was designed with some stabilizers in the flux to allow welding on AC without the arc snuffing out.
6011 rods will run on AC , DC straight , or DC Reverse ( also called DC positive and DC neg)
Whereas 6010 rods typically only run ok on DC

Both the Harbor Freight rod and the Lincoln rod that I have can be used for both AC and DC.
