Which numbers of electrodes run on both DC positive and AC?

• A. 5, 0
• B. 8, 6, and 1
• C. 3, 4
• D. 2

Answer: (B)

The selection of the group that includes electrodes capable of running on both DC positive and AC is based on their design and composition. Electrodes that can be used in both modes typically possess certain properties, such as a suitable coating that allows them to maintain effective arc stability and deposit quality regardless of the current type. The specific classifications of electrodes mentioned in choice B—8, 6, and 1—are known for their versatility, allowing them to perform well under both DC positive and AC conditions. These electrodes leverage characteristics such as good arc stability and the ability to produce a quality weld in varying environments, which makes them suitable for different applications and welding scenarios. Understanding the behavior of these electrodes in both direct current and alternating current modes is crucial for welders, as it enables them to select the right electrode based on the specific requirements of the job, including material types, thicknesses, and welding positions. This knowledge is essential for achieving optimal results and meeting structural welding codes effectively.
