Electrode and the molten weld pool, and provides the required arc characteristics. The process may employ direct current with positive or negative electrode or alternating current. In gerenal, AC is preferred for welding aluminum and magnesium. Direct current electrode negative is preferred for ...
The polarity you need depends on the type of metal you are welding.For mild steel and stainless steel, you should use direct current electrode negative (DCEN), which means that the current flows from the tungsten to the metal. This creates a narrow and deep penetration and concentrates most ...
In TIG welding, the tungsten electrode and the workpiece act as the positive and negative electrodes, respectively, with inert gas serving as the arc medium, and the welding power supply providing the necessary voltage and current. The arc formation process in TIG welding involves: Thermionic Emiss...

TIG welding in AC (Figure 2B) allows the electrode positive (EP) portion of the cycle to blast away the aluminum oxide while the electrode negative (EN) portion melts the base metal. A feature called AC balance control allows operators to tailor the EP to EN ratio. If you notice a brown...
