I like 3/32 rods better for most applications, use 6011s on dirty metal, 7014s on clean metal. Strike an arc like striking a match, if it sticks to the metal up the amps some until it burns the rod, if you are having trouble burning thru, move the rod a little faster.

A good weld arc should sound like frying bacon, work with the heat until you can  somewhat achieve this sound.

The post that said practice on some heavy metal is good. When you get to the point of an acceptable bead, move on to thinner metal until you can run a bead on the thin stuff. 

You will find that cleaning the weld with a chip hammer and wire brush is good practice, it will let you look at flaws and allow another bead to be welded over the first bead.
Before doing any welding get yourself a good welding helmet. Find a comfortable one and have fun.
