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.	Sine Wave DC/AC sine wave, rectangular transition at zero-crossing point, less and softer arc noise.
Triangle Wave Short peak-time and low heat input, suited to welding of thermo-sensitive metals as thin plates.	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.
