Multiple Waveform controls provide optimal combination according to welding needs
- Square Wave – Precise control in current waveform and accurate adjustment in parameters of peak current, base current, frequency and others, with high arc stability and good dynamic characteristics, applicable for various stainless steel welding.
- Trapezoidal Wave – Soft arc brings good wetting effect to fusion pool, suited to groove welding and overhead welding.
- Triangle Wave – Short peak-time and low heat-input, suitable for thin sheet welding.
- Sine Wave – Arc noise is smaller and softer
