Multiple Waveform controls provide optimal combination according to welding needs
- Square Wave – DC/AC square wave, polarity fast-switching, high-stability of arc, good dynamic characteristics, strong ability to clean aluminium oxide film, suitable for a wide range of aluminium and aluminium alloy welding.
- Trapezoidal Wave – DC/AC trapezoidal wave, polarity stable-switching, soft arc brings good wetting effect to fusion pool, applicable for groove welding and overhead welding
- Triangle Wave – Short peak-time and low heat-input, suited to welding of thermo-sensitive metals as thin plate
- Sine Wave – DC/AC sine wave, rectangular transition at zero-crossing point, less and softer arc noise
