What is the heat distribution with DCEN welding current?

To determine

The heat distribution with Direct Current Electrode Negative (DCEN) welding current.


DCEN stands for Direct Current Electrode Negative. It is produced when the electrode of a welding unit is connected to the negative terminal and the workpiece is connected to the positive terminal.

When the electrons start to flow from the negative terminal to the positive side, that means from electrode to the workpiece, about 70% of heat is generated near the workpiece. The remaining 30% heat is generated on the electrode
