Which of the following is a way to minimize erosion of the tungsten electrode?

Question

Quizplus · Accepted Answer

Using DCEN (Direct Current Electrode Negative) current can help minimize erosion of the tungsten electrode by reducing the transfer of material from the electrode to the workpiece. This is because the electrons flow from the electrode to the workpiece, preventing the tungsten from melting and eroding as quickly as it would with DCEP (Direct Current Electrode Positive) current. Using a smaller size of tungsten electrode can also help minimize erosion, but it is not as effective as using DCEN current. Using as high a current as possible and using an air-cooled torch can actually increase erosion of the tungsten electrode.
