In what scenario is pulsed current particularly advantageous?

Pulsed current is particularly advantageous when better puddle control is required due to its ability to provide a more stable arc and improved heat input management. In pulsed current welding, the welder can vary the current between a high peak value and a low background value, which allows for greater control over the molten weld pool. This is particularly useful in situations where a more precise control of the puddle is necessary, such as in thin materials or intricate joint configurations, where excessive heat can lead to warping or burn-through.

This capability to finely tune the heat input helps in achieving a more controlled and consistent weld bead, contributing to enhanced weld quality. By using pulsed current, welders can also minimize the risk of defects while improving their ability to manipulate the weld pool, which is essential for high-quality welds.
