DATA DISPLAY ON A WELDING SCREEN

摘要

This invention relates to a welding unit comprising a welding device (1) and a protection unit (28), in particular a protective screen (29) for an operator or a welder. The protection unit (28) has an electrically operable, commandable- and/or controllable visor (31) with a control device (32). The welding device (1) or the welding unit is at least composed of an electrical source (2), a welding torch (10) and a control unit. The protection unit (28) has a transmitter and/or a receiver (33), which is connected to the control device (32). The transmitter and/or receiver (33) is connected to the welding unit or welding device (1) or the welding torch (10) via a connecting cable (35) or by wireless means. Darkening of the protective visor (31) occurs after the control unit or the welding torch sends out a signal to the transmitter and/or receiver (33) which is relayed to the control device (32) after activation of a start switch (27) disposed on a welding torch (10) or on the welding device (1) or by virtue of a start command.
