They deliver deep penetration and the ability to dig through rust, oil, paint and dirt. Many experienced pipe welders use these all-position electrodes for root welding passes on a pipe.
However, E electrodes feature an extremely tight arc, which can make them difficult for novice welders to use. E electrodes can also be used for all-position welding using an alternating current AC welding power source. Like E electrodes, E electrodes produce a deep, penetrating arc that cuts through corroded or unclean metals. Many welders choose E electrodes for maintenance and repair work when a DC power source is unavailable. E electrodes work well in applications that require gap bridging between two joints.
Many professional welders also choose E electrodes for high-speed, high-current fillet welds in the horizontal position, but these electrodes tend to produce a shallower penetration profile and dense slag that will require additional post-weld cleaning.
E electrodes produce a soft arc with minimal spatter, offer moderate penetration and have an easily-removable slag. These electrodes should only be used to weld clean, new sheet metal. What are the differences between E, E and E electrodes and when should they be used?
E electrodes produce about the same joint penetration as E electrodes and are designed for use on carbon and low-alloy steels. E electrodes contain a higher amount of iron powder, which increases deposition rate.
They can also be used at higher amperages than E electrodes. E electrodes contain a thick flux with high powder content and are one of the easiest electrodes to use. These electrodes produce a smooth, quiet arc with minimal spatter and medium arc penetration. Many welders use E electrodes to weld thick metals such as structural steel.
E electrodes also produce strong welds with high impact properties even in cold weather and can be used on carbon steel, high-carbon, low-alloy or high-strength steel base metals. E electrodes contain a high amount of iron powder that helps increase deposition rates. Many welders use E electrodes for high-speed horizontal or flat fillet welds. How do I choose a stick electrode? What function does the flux surrounding a stick electrode serve? When should a high deposition stick electrode be used?

For starters, there are consumable and non-consumable electrodes. There are light and heavy coated electrodes. Light coated electrodes have a light coating that is applied through brushing, spraying, dipping, washing, wiping, or tumbling. Heavy coated electrodes are coated by extrusion or dripping. There are three main kinds of heavy coatings: mineral, cellulose, or a combination of the two. Heavy coatings are used for welding cast iron, steels, and hard surfaces.
