i use 1/8" 7018 rods at school. it's an all positions rod and gives me some nice welds. if i'm doing vertical or overhead i'll usually start with a 3/32" 7018 and do a second pass with the 1/8". hope this helps.

the 70 is breaking strength in 1000's of psi (70,000 lb breaking strenght)
the 1 is all positions (flat, horizontal, vertical, and overhead)
the 8 is the chemical composition

that's a test question.

Using a single phase AC machine I'd just stick with the 7014. 7018 and single phase is just a PITA IMO.
