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.
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.
DC/AC sine wave, rectangular transition at zero-crossing point, less and softer arc noise.
Short peak-time and low heat input, suited to welding of thermo-sensitive metals as thin plates.
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.
Unique circuit design supports arc to start at 3A and stabilize at 3A in DC welding, ensuring continuous arc in a very small current.
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.
