What is a defining feature for electrodes that use the dragging manipulation technique?

Electrodes that employ the dragging manipulation technique typically feature a numbering system where they end in the digits 2, 3, 4, 5, 6, 7, and 8. This specific designation reflects the design and functionality of the electrodes suited for this technique.

In the dragging technique, the operator maintains a consistent angle and distance from the workpiece, allowing for controlled heat and penetration, which is essential for creating a strong weld. The numbers corresponding to these electrodes indicate their intended use with different materials and applications, particularly when working with horizontal or flat surfaces.

Understanding the characteristics of electrodes and their associated manipulation techniques is vital for achieving the desired weld quality and integrity. This is why familiarity with the electrode designation system is crucial for welders, ensuring they select the appropriate materials based on the welding method and environmental conditions.
