| Software notes | The machine is governed by a microprocessor control that manages the synergic logic of the welding process. The user simply selects the thickness of the material to be worked, and the system automatically adjusts the wire speed and the optimal arc voltage. This internal software drastically reduces setup times and prevents configuration errors typical of traditional power sources. There are no interfaces for computer connection, external firmware updates, or wireless connectivity, as the entire digital ecosystem is permanently integrated into the internal electronic board. The system is designed to be autonomous, offering an immediate user experience focused on the stability of the electric arc during real-time operation. | As a step-regulated transformer welding machine, it features no management software or digital interface. Parameter control is purely electromechanical via selectors on the front panel, providing 10 positions for voltage adjustment along with potentiometers for manual regulation of wire feed speed and spot-welding time. |
