Overview of Cut-55DS Pro Features

The Cut-55DS Pro arrives as an innovative advancement in YesWelder’s lineup, boasting a range of new features that significantly enhance its functionality and user experience.

At the forefront of these improvements is the transition from a high-frequency start to a blowback start mechanism.

This shift is more than just a technical upgrade; it represents a thoughtful response to the needs of both the equipment and its operators.

One of the most notable advantages of the blowback start is its compatibility with sensitive electronics.

Unlike the high-frequency start, which can potentially interfere with or damage electronic components like ECUs, body control modules, and keyless start systems in modern vehicles, the blowback start mechanism is much gentler on these systems.

This feature is crucial, especially when working in close proximity to electronic-laden vehicles or equipment, providing peace of mind that the plasma cutter won’t inadvertently cause harm.

The blowback start also offers a significant benefit for individuals sensitive to high-frequency emissions. High-frequency starts can create a distinct electrical noise, sometimes leading to discomfort or disorientation in some users.

By eliminating this high-frequency noise, the Cut-55DS Pro ensures a more comfortable and safer working environment, especially important for those spending extended periods with the machine.

Comparing the traditional high-frequency start to the new blowback mechanism highlights several key differences. The high-frequency start works by generating an electrical arc to initiate the main cutting arc.

While efficient, this method creates the aforementioned electrical noise and poses risks to sensitive electronics.

On the other hand, the blowback start initiates the pilot arc with an air flow; once the pilot arc is retracted into the torch, it triggers the main arc.

This process not only reduces the risk of electronic interference but also provides a more crisp and immediate start to the cutting action.
