I was reading on the Miller website an explanation of rods. It said
that 7018 rods are "not recommended for use in small ac arc welders".
Does this mean I should not use it with my Lincoln ac 225 amp welder?
What is the ideal rod for the machine I have?

For general purpose use on mild steel, 1/8" 6011

You're both right. 6011 penetrates better, use it for steel over say 3/16
thick. Also burns through paint, crud, and rust. 6013 won't burn a hole as
easily, use it on thin material.
one more, 7014. its great to fill up that hole you burned through.

I've done it successfully, even on large, multi-pass fillets. Low-
hydrogen rods are "persnickety" about maintaining a stable arc. If your
welder isn't a really stiff current supply that won't vary much with load
and input voltage variations, it's hard to keep the arc steady.
On the other hand, my forever-old Craftsman 225 variable worked OK on
them, after a few bad beads and some current adjustments.
I'd rather have DC and RF stabilization for Low-H rods, but I don't do
enough welding to justify the expense.
The "ideal" rod for any slap-up welding on mild steel is the venerable
E6011. That rod will run a good bead all by itself, just leaning against
the work.

In the other reply, Ned also recommended 6011, and that is the most
common reply to a "What all-round rod is good?" question. But I gotta
say that I like 6013 much better. My welding is little & far between,
so I get out of practice & maybe that's why I find the 6013 better. For
me, it's much easier to strike and run than 6011. It's also said that
6011 is better for rusty steel, but I haven't had a problem with 6013 &
rust.
I've never even tried 7018 because of the need to keep it dry. It's
advantage couldn't be worth the extra fussin'. For me.
Not at all an expert, just a guy with an opinion,
Bob
