Electrode positive (DCEP) in stinger arc welding increases penetration. In contrast, electrode negative (DCEN) produces a flatter weld. In DCEP, the electrode is the positive pole, and the workpiece is negative. Select polarity based on desired weld characteristics and follow the manufacturer’s guidelines for the best results. Understanding electrode polarity is crucial in stinger arc … Read more

The principle of electric arc welding involves creating an electric arc between the welding electrode and the workpiece. This arc produces a high-temperature flame that melts the metal. As the molten metal cools, it forms a strong welding joint, ensuring a durable connection between the workpieces. The operation of electric arc welding requires precise adjustments … Read more

Metal arc welding works by creating an electric arc between two electrodes. When voltage rises, it breaks down air insulation, enabling current flow. This process produces bright light and high heat, which melts the metal at the joint. As a result, it forms a strong bond during the welding process. There are several types of … Read more

In arc welding, an electrical arc occurs between the positive voltage electrode and the negative voltage base material. This process uses an output current of 5 to 1,000 A and an output voltage of 8 to 40 V. The heat from the arc melts the welding rod or wire and the base material, allowing them … Read more
