TIG Series Welding Machine With Pulse AC DC
This state-of-the-art welding machine incorporates IGBT high-frequency inverter technology, offering unparalleled power efficiency and performance.
The unit supports both 3-phase 380V and single-phase 220V power input, converting it seamlessly through direct rectification. The inverter, consisting of advanced IGBT components,
transforms the electricity into high-frequency AC power. This resultant high-frequency AC is then stepped down to a lower voltage by a high-frequency transformer.
The reduced high-frequency current is subsequently rectified and filtered, delivering a stable DC output ideal for welding operations. Additionally, the AC-wave current,
ranging from 50 to 150 Hz, can be precisely controlled by the secondary inverter. Whether it's manual arc welding or DC constant current argon arc welding,
this machine handles it all with ease. It excels in DC pulse argon arc welding and AC constant current argon arc welding,
as well as AC pulse argon arc welding. It's the go-to solution for welding a variety of materials including carbon steel, copper,
titanium, aluminum, and aluminum-magnesium alloys. The innovative design enhances the machine's dynamic response,
while minimizing the size and weight of critical components like transformers and reactors. This results in improved efficiency and portability.
The machine's advanced technology significantly optimizes the dynamic response, reduces the volume and weight of the transformer and reactor, and boosts the overall efficiency.
