When performing SMAW with an electrode designated as DCEP, which terminal would you plug the ground clamp into?

In Shielded Metal Arc Welding (SMAW), the designation DCEP stands for Direct Current Electrode Positive. This specification indicates that the electrode should be connected to the positive terminal of the power supply while the workpiece or ground clamp should be connected to the negative terminal.

When the electrode is connected to the positive terminal, it results in a more stable arc and higher heat concentration at the electrode, which enhances penetration and welding capabilities. This setup effectively allows for better fusion of the metals being welded, making it ideal for certain applications and materials.

Understanding the function of the terminals in SMAW is crucial for achieving optimal welding results. In this context, connecting the ground clamp to the negative terminal allows for the flow of current as needed for efficient welding, aligning perfectly with the requirements for DCEP operation.
