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?

Should be fine on your "tombstone" welder. It's plugged into 220 VAC and
is a "real" welder from that point of view. The "small" welders in
question are 110V supply buzzboxes, which lack sufficient open current
voltage for proper operation, if I recall the reason correctly.
The ideal rod depends, as usual, on what you are doing. If you need
7018, it's the ideal rod for that job. If you have the skill to run it
well, it can do a lot of jobs. For low-stress clean steel, 6013 is a
nice all-position rod, and makes a pretty bead. For filth and rust
encountered in maintenance welding, 6011 is good, if ugly. 6010 is
better if you have DC. One of the 60 series is supposed to be dead
simple for flat welds, but I don't have enough flat welds to bother
remembering what it is (14 or 24, I think), or buying any. Nickel is
good if you need to repair cast iron. Hardface is good if you need to
make things wear resistant. A carbon arc torch is good if you need to
heat and braze things and don't own an oxy/acetlyene torch...

With your welding experience, I would just use any rod. Any polarity. Any
size. Results will be the same.

Political Correctness is a doctrine fostered by a delusional,
illogical liberal minority, and rabidly promoted by an
unscrupulous mainstream media, which holds forth the
proposition that it is entirely possible to pick up a turd by the clean end.

I agree Steve's response might not be the best encouragement to a
newcomer to welding, but stryped is talking about building a trailer,
presumably to be used on the public roads.
His skill level doesn't appear to be anywhere near adequate to attempt
that project. It's not only his life, health, or safety that are at
stake.
Steve's reply might be cold, but it's accurate at this time. stryped
would be far better off buying a trailer. For that matter, so would I.
Most all of my experience is short welds on small stock, wheelchair and
mobility aids parts where I _have_ to practice a few beads before I even
start on the workpiece because there's no room or material to mess up
and do over. I've never had one of my welds fail, but I'd know just
enough to be dangerous, building a trailer.
A man's gotta know his limitations. :)
_Then_ he can to learn to extend them.
