Abstract

A welding and cutting device, and a welding and cutting arc light-preventing method therefor. The welding and cutting device comprises a welding and cutting power supply, an eye-protecting apparatus, and a welding and cutting apparatus (3). The welding and cutting power supply is electrically connected to the welding and cutting apparatus (3); the welding and cutting power supply and the welding and cutting apparatus (3) are connected by means of a cable; the eye-protecting apparatus is a welding helmet (2), welding goggles, welding glasses, or an arc light-preventing baffle; the welding apparatus (3) is a welding gun, a cutting gun, or a welding rod; a first signal module is arranged in the welding and cutting power supply; the eye-protecting apparatus is provided with a liquid crystal light valve for protecting eyes during welding and cutting; a liquid crystal light valve control circuit, a liquid crystal light valve detection circuit, and a second signal module are arranged in the eye-protecting apparatus; the first signal module is connected to the second signal module in a wireless or wired manner, thereby ensuring that the liquid crystal light valve becomes black firstly and then arc welding is conducted, and effectively ensuring that a welder is prevented from being damaged by arc light, wherein the wireless manner is a connection manner such as bluetooth, WIFI communication, or 2.4G communication.

Abstract

Provided is an automatic light-emitting welding mask with Bluetooth communication and head-up display functions. The welding mask comprises a mask body, wherein a display screen is mounted at the front surface of the mask body, and a viewing port is provided at the front surface of the mask body, the front surface of the mask body being sequentially sprayed with a first anti-radiation layer, a first flame-retardant layer, a second flame-retardant layer, a first high-temperature-resistant layer, a second high-temperature-resistant layer and a second anti-radiation layer. According to the automatic light-emitting welding mask with Bluetooth communication and head-up display functions provided in the present invention, a first anti-radiation layer is provided as the outermost layer to absorb radiation generated in an electric welding process, thereby reducing the harm to a user; and by means of setting Bluetooth signal matching, the user can receive information of an external device with a Bluetooth function in a timely manner during a working process to perform communication and control on information of a mobile phone and a welding machine, thereby improving the practicability of the welding mask and facilitating the use of the welding mask by the user.

Abstract

A telescopic welding mask, comprising an outer casing (1) and a mask casing (2); the outer casing (1) and the mask casing (2) are connected by means of an annular soft sleeve connector (3), and the arched area of the mask casing (2) is smaller than the area of of the outer casing; bolt pieces (4) are installed on the outer surfaces of two side edges of the outer casing (1); a viewing window (5) is provided on the outer surface of the middle of the mask casing (2), and the two sides of the top of the viewing window (5) are provided with rotary adjustment buttons (6). The mask casing (2) may be folded and depressed into the outer casing (1) under the action of the annular soft sleeve connector (3) after being manually pressed, so that the whole welding mask has a telescopic folding action, and has the effect of folding multiple times. Thus, the area of occupied space may be reduced, and at the same time, transportation costs are reduced.
