Control panel for a welding tool comprising - a welding parameter display unit for displaying welding parameters and comprising - at least one control element manually actuable by a user, wherein the control panel can be switched between a welding parameter selection mode and a welding parameter editing mode by actuating the control element; in the welding parameter selection mode, one of the welding parameters of the welding parameter display unit can be selected by turning the control element; in the welding parameter editing mode, a parameter value of a selected welding parameter of the welding parameter display unit can be set by turning the control element; characterised in that the control panel is set up in such a way that, after a welding process performed by the welding tool is started, it switches into a welding parameter display mode; in the welding parameter display mode, after the welding process is started, the welding parameters are displayed sequentially in a partitioned function curve of the welding parameter display unit of the control panel in different successive phases of the welding process in accordance with the parameter value set in the welding parameter editing mode, and are physically set by a welding power source of the welding tool to perform the welding process; each welding parameter is displayed by an associated display segment of a partitioned function curve of the welding parameter display unit; in the welding parameter editing mode, the display segment of the selected welding parameter within the partitioned function curve of the welding parameter display unit is lit at full, undimmed luminosity by the associated lighting means, whilst the display segments of the other, unselected welding parameters within the partitioned function curve of the welding parameter display unit are not lit by the associated lighting means; and in the welding parameter selection mode, the display segment of the selected welding parameter within the partitioned function curve of the welding parameter display unit is lit at full, undimmed luminosity by the associated lighting means, whilst the display segments of the other, unselected welding parameters within the partitioned function curve of the welding parameter display unit are lit at a dimmed luminosity by the associated lighting means. - a welding parameter display unit for displaying welding parameters and comprising - at least one control element manually actuable by a user, wherein the control panel can be switched between a welding parameter selection mode and a welding parameter editing mode by actuating the control element; in the welding parameter selection mode, one of the welding parameters of the welding parameter display unit can be selected by turning the control element; in the welding parameter editing mode, a parameter value of a selected welding parameter of the welding parameter display unit can be set by turning the control element; characterised in that the control panel is set up in such a way that, after a welding process performed by the welding tool is started, it switches into a welding parameter display mode; in the welding parameter display mode, after the welding process is started, the welding parameters are displayed sequentially in a partitioned function curve of the welding parameter display unit of the control panel in different successive phases of the welding process in accordance with the parameter value set in the welding parameter editing mode, and are physically set by a welding power source of the welding tool to perform the welding process; each welding parameter is displayed by an associated display segment of a partitioned function curve of the welding parameter display unit; in the welding parameter editing mode, the display segment of the selected welding parameter within the partitioned function curve of the welding parameter display unit is lit at full, undimmed luminosity by the associated lighting means, whilst the display segments of the other, unselected welding parameters within the partitioned function curve of the welding parameter display unit are not lit by the associated lighting means; and in the welding parameter selection mode, the display segment of the selected welding parameter within the partitioned function curve of the welding parameter display unit is lit at full, undimmed luminosity by the associated lighting means, whilst the display segments of the other, unselected welding parameters within the partitioned function curve of the welding parameter display unit are lit at a dimmed luminosity by the associated lighting means.
