Some of our customers have inquired about the use of AC waveform on aluminum welding, now we show you one by one and let's take a look to see how their differences.
Many professionals know that there are 3 types maybe 4 are frequently used on AC welders in the global market, they are Square wave, Soft square wave, Sine wave, Triangular wave. But on SANJOE AC/DC welders, there are 6 waveforms inside, other 2 types are front triangular, back triangular.
The advanced square wave waveform offers fast transitions between EN and EP for a responsive, dynamic, and focused arc with better directional control. It forms a fast-freezing puddle with deep penetration and fast travel speeds.
The sine wave offers a soft arc with the feel of a conventional power source. It provides good wetting action and actually sounds quieter than other waves. Its fast transition through the zero amperage point also eliminates the need for continuous high frequency.
The triangular wave offers peak amperage while reducing overall heat input into the weld. This leads to quick puddle formation, low weld distortion, and fast travel speeds. It is especially good for welding thin aluminum.
The front triangular fundamental of welding is similar like the triangular wave, but it focus on heating of injection, it has a better penetrability.
The front triangular fundamental of welding is similar like the triangular wave, but it focus on heating of injection, it has a better welding shaping.
Soft square wave provides a smooth, soft, “buttery” arc with a fluid puddle and good wetting action. The puddle is more fluid than with advanced square wave and more controllable than with sine wave.
1, Different materials, thickness... It's a challenge for high quality aluminum welding projects, above 6 waveforms can help users to finish jobs successfully.
2, Besides, users can combine with the AC Frequency or AC duty cycle setting, to get more better welding experiences.
