General

The operator interface on the welding machine, also known as the HMI or Touch Panel, is the device through which all control, configuration and display of machine/tool settings can be carried out. The operator interface consists of a touch screen monitor and software, developed by CEMAS Elettra s.r.l., which allows quick navigation within the panel and simple use of it by the operator. All the pages of the Operator Panel are divided into two areas: the internal area, where the icons that allow access to the different functions of the panel according to the specific function required are visible, and the external area, known as the frame, where the fixed icons are visible, i.e. the icons that are always visible and usable while navigating in the panel.
