Arc with a 110v buzz box is a little harder to strike an arc but once you learn it, it's not hard. Back when I ran 1, I always used a piece of scrap clamped to the ground and piece to be welded to start the weld. Once the tip is glowing red, you won't need to strike the arc unless you let it cool.. I always used 6013 3/32".
With the Lincoln AC/225 I use now, I burn only 1/8" 7018 rod between 75A and 110A. Very versitile rod, and I'v welded right down to 18ga steel. But 7018 only comes in 1/8" I think, which is too thick for a 110v welder.
