A little addendum to Ray's good info.
With the 60xx rods, ( for mild steel) you can generally get away with 
drying them out in the kitchen oven . The rods with 70xx #s are " generally 
low hydrogen rods and are quite sensitive to moisture ( underbead 
cracking)  .The higher the number the drier it must be kept generally. I've 
roasted 7018 thoroughly and used it without problem  for shop tools and 
stuff but where lives are depending on the weld..get new fresh stuff. I 
also use trash rod for general non-critical applications...but then I'm a 
fool that way..used to making sculpture on dinky budgets.
Those little buzz boxes are wonderfully versatile tools...get to know the 
different rods available..you'll be amazed at the stuff you can do....P
