Step 1
Learn the numbering code to properly maintain and store the electrodes. According to the American Welding Society's numbering system, the first 2 numbers of the electrode are the tensile strength of the metal inside the electrode. A 60 series electrode has the strength of 60,000 pounds. The third number indicates the position the electrode can be used in, such as horizontal, vertical or all positions. The fourth number shows the properties of the flux that's used on the electrode.

Step 2
Store most electrodes in a dry place in the original box they came in. Welding electrodes can absorb moisture on the flux if not stored properly, and moisture can cause pinpoint bubbles in the weld. The flux is the covering on the electrodes. These pinpoint bubbles cause the weld to become porous and weak. When welding with these electrodes, the weld can crack and be defective. Always store your welding electrodes in a dry place.

Step 3
Use the welding electrodes before they become too old. An old electrode becomes coated with a frosted appearance called "efflorescence" which lets you know it's time to use it.

Step 4
Buy an electrode oven for your welding electrodes, especially number E7018. This electrode makes a very strong weld, and is common in the construction industry but it also requires special care. Use a stabilizing oven to store and maintain electrode E7018 so it will keep it's bonding strength and stay dry. You can buy an electrode oven for as low as $150.00.
