2. Multiple waveform controls provide optimal combination according to welding needs

1) Multiple selections with a triangle wave, square wave, sine wave, trapezoidal wave, and others;

2) The optimal setting for the waveform in different welding phases;

3) EN/EP range ratio is able to be adjusted to efficiently clean oxide film on the surface while ensuring the depth of penetration.

Square Wave

DC/AC square wave, polarity fast-switching, high stability of arc, good dynamic characteristics, strong ability to clean aluminum oxide film, suitable for a wide range of aluminum and aluminum alloy welding.

Square Wave - MetaTIG ACDC HF TIG Welders 315A

Sine Wave

DC/AC sine wave, rectangular transition at zero-crossing point, less and softer arc noise.




Sine Wave - MetaTIG ACDC HF TIG Welders 315A

Triangle Wave

Short peak-time and low heat input, suited to welding of thermo-sensitive metals as thin plates.


Triangle Wave - MetaTIG ACDC HF TIG Welders 315A

Trapezoidal Wave

DC/AC trapezoidal wave, polarity stable-switching, and soft arc bring a good wetting effect to the fusion pool, applicable for groove welding and overhead welding.

5. AC-DC Pulse

1) DC is blended into AC-wave to further raise the heat input of base metal and increase the depth of penetration;

2) In AC-DC Pulse, tungsten rod loss could be reduced in DCEN;

3) In AC-DC Pulse, the EP ratio is adjustable in the AC section to improve the cleaning effect;

4) Arc stiffness and concentration are good and heat input is high to further improve welding efficiency.
