Arc Welders are very popular and can be purchased in many great brand names today. Arc welding is just one of many fusion processes for joining different metals together. In the process of Arc Welding, the intense heat that is needed to melt the metal is produced by an electric arc.
Arc welders use welding rods and are usually put to work welding thicker pieces of steel. The welding rod is actually struck on the object to be welded and the arc thus melts both the metal object and the welding rod. As the welder moves the welding rod along the designated area to be welded, a very solid, strong welding bond is formed.
