The invention describes a welding system with a welding device (1) and a protective device (28), in particular a protective shield (29) for a user or welder. The protective device (28) has an electrically controllable and/or adjustable protective visor (31) with a control system (32). The welding device (1) or the welding system consists of at least one current source (2), a welding torch (10) and a control unit. The protective device (28) has a transmitter and/or receiver unit (33) which is connected to the control system (32). The transmitter and/or receiver unit (33) is connected to the welding system or the welding device (1) or the welding torch (10) via a connecting line (35) or alternatively wirelessly and, when a start switch (27) disposed on the welding torch (10) or on the welding device (1) is activated or when a start command is issued, the control unit or the welding torch (10) sends a signal via the transmitter and/or receiver unit (33) to the control system (32) to darken the protective visor (31).
A welding system comprising a current source, a welding device, a control unit, a starting switch, and a protective device for a user, the protective device having a protective visor with a control system for electrically controlling the protective visor and a transmitter/receiver unit connected to the control system, the transmitter/receiver unit being also connected by a connecting line or wirelessly to the welding torch, and the starting switch being adapted, upon actuation, to cause the control unit to send a starting signal via the transmitter/receiver unit to the control system to darken the protective visor and, after a pre-settable run-in time or gas run-in time, to initiate a welding process.
A control method for a welding system comprising a current source, a welding device, a control unit, a starting switch, and a protective device for a user, the protective device having a protective visor with a control system for electrically controlling the protective visor and a transmitter/receiver unit connected to the control system, the transmitter/receiver unit being also connected by a connecting line or wirelessly to the welding torch, the control method comprising the step of causing the control unit, upon actuation of the starting switch, to send a starting signal via the transmitter/receiver unit to the control system to darken the protective visor and, after a pre-settable run-in time or gas run-in time, to initiate a welding process by igniting of an arc.
