Digital AC + DC Hybrid Pulsed TIG Welding Machine
The DA300P comes equipped with new AC Frequency Variable Control
Variable AC Frequency Control
The DA300P features an all-new AC Frequency variable control systems that provide the ideal conditions for various aluminum thin plate welding applications. The AC Frequency has a greater arc concentration when compared with conventional machines, and this allows the user to obtain the desired weld penetration and heat input.
The AC Frequency control can be set between 50 and 200 Hz for desired frequency and bead shape while keeping noise in the production environment to a minimum.
AC Frequency Control
Even when the AC frequency is increased, there is only a slight decrease in welding current, resulting in consistent weld quality.
Variable AC Frequency Control Examples
The DA300P comes equipped with new AC Frequency Variable Control, which provides the followings features:
Even if the AC frequency increases, the weld current remains largely unchanged, providing uniform welding quality.
