Sage Advise---Keep your rods dry!!! I know that sounds a bit personal, but the flux coating on stick electrodes are a real bear to soak up moisture out of the air. They won't look any different, but they will stick, and sputter, and give you grief when you are trying to use them. Most professional welding shops that use stick welders store the rods in a low heated environment that ensures that they stay dry untill ready to use. Many old welding rods that have been stored in a garage in high humidity can be given a new lease on life by heating them under a very low heat overnight in an oven---NOT THE ONE YOUR WIFE COOKS IN!!!
