While modern inverters offer flexibility, the fundamental physics of the arc remain unchanged, dictating metal behavior, penetration, and overall weld quality. The direction of electron flow determines how this energy is distributed.
Balancing Cleaning Penetration When Choosing AC or DC TIG Current
Understanding the distinct characteristics of alternating current versus direct current is essential for achieving consistent, high-strength welds on a variety of materials. Magnesium and its alloys also necessitate AC, though often at lower amperage settings than aluminum to prevent electrode erosion.
In this setup, the electrode is negative, and the workpiece is positive. Direct Current Electrode Negative (DCEN) Penetration and Cleaning Action DCEN is the most common mode for standard TIG welding of steel and stainless steel.
