METHOD FOR OPERATION OF A WELDING UNIT WELDING UNIT AND WELDING TORCH FOR SUCH A WELDING UNIT

摘要

The invention relates to a method for operation of a welding unit (1), for the execution of welding processes with a welding device (2) and a welding torch (10), whereby operational states for the welding processes are recorded and, depending on the operational state, vibrations which may be felt are generated and a welding unit (1) and a welding torch (10), for carrying out said method. According to the invention, the possibility of providing feedback about particular operational states to people involved in the welding process, in particular, the welder, without the same having to look away from the welding spot or the arc (15) may be achieved, whereby, in particular, the welding current (I) or the welding voltage (V) are modulated, depending on the operational state, to generate acoustic vibrations in the arc occurring during welding, or, depending on the operational state, mechanical vibrations are generated. The vibrations can also be felt by the welder without looking away from welding spot or the arc (15).
