Software notes The user interface is managed via a large, clear LCD panel that displays critical welding parameters in real time. The machine includes dozens of pre-set synergic curves for various wire and gas combinations straight out of the box. The control electronics offer advanced functions specifically designed for aluminum welding, such as automatic Hot Start and Crater Filler. The welder's operating system is highly expandable: it can be upgraded to include pulsed and double current level welding functions through optional software packages provided by the manufacturer, allowing users to broaden the machine's capabilities according to future production needs.
