The total number of times the AC TIG arc changes in between the electrode negative and electrode positive in one second is known as Frequency or Hz. Take in consideration the Miller’s Dynasty 300 DX inverter-based TIG power source, it always allows to alter the frequency of the power supply from 20 to 250 Hz.

It’s notable that usual TIG machineries have a fixed amount of frequency which is something to that of a 60 Hz of primary power. When the frequency of the power sources is increased, you can find that it trims the shape of the arc cone and boosts up the arc force. Because of this the arc is reduced and stabilized, moreover gives exceptional directional direct on the arc.

On lap and T-joints, by a high frequency gives ways to set up the weld puddle right at the root. Resultantly, we get a good infiltration and moreover the etch zone is also minimized.
