摘要： A welding torch includes a main body and an end portion suited to be fed through the main body with a welding wire and a shielding gas. The end portion includes a welding unit electrically powered and provided with an internal channel for the passage of the welding wire. A conveyor element is provided with an outlet mouth to allow the welding wire to move out of the welding unit and to allow the shielding gas to be conveyed outside of the welding unit. Electrical insulation means are interposed between the welding unit and the conveyor element with an insulation portion made of an electrically non-conductive material. The welding torch includes the conveyor channel suited to convey the shielding gas from the main body to the outlet mouth of the conveyor element. The conveyor channel is delimited at least partially by the insulation portion.

摘要： A welding torch includes a first terminal zone provided with a welding electrode and a conveyor element associated with the electrode. The torch includes a first body connected to the electrode through a first conductor element and a second body connected to the conveyor element through a second conductor element. The torch includes a delivery way suited to convey a cooling fluid towards the first terminal zone and a return way for the cooling fluid coming from the terminal zone. One of the delivery way and the return way passes through the first body and the second body. It includes a tubular element made of an electrically insulating material having a first end inserted in a seat provided in the first body and a second end inserted in a seat provided in the second body.

摘要： System has an optical sensor (1), an aperture with the optical element (2) with the changeable permeability and an activation light (3) emitting radiation, which is detected by the optical sensor (1). The activation light is connected with the switch (4) and it is placed within the reach of the optical sensor (1). Within a device which realizes the technological process with the luminous manifestation the instruction for the beginning of a given technological process is detected and on the basis of this instruction the activation light (3) lights up. This activates the optical sensor (1) by means of the activation light (3) before the optical sensor (1) detects the luminous manifestation of the technological process itself. The activation light (3) can be a simple infrared LED diode. The advantage lies in the fact that the protective device itself does not have to be modified in any way and its reaction time can be shortened to zero, or negative reaction time can be achieved since we use time passing during the initiation of the technological process before the appearance of the luminous manifestation for the darkening.
