Auto-power-off explosion-proof conducting wire welding device and use method thereof

Abstract

The invention provides an auto-power-off explosion-proof conducting wire welding device and a use method thereof. The auto-power-off explosion-proof conducting wire welding device is used for overcoming the problems that the existing conducting wire welding devices cannot directly operate in an explosion-proof operating area and the temperature cannot be accurately controlled. The auto-power-off explosion-proof conducting wire welding device has the functions of power-off welding, adjustable temperature, voice prompt and electrical explosion protection. The welding device comprises an explosion-proof isolating power supply (1), an explosion-proof control box (3), a welding pedestal (8), an infrared transmitting and receiving module (10), a searing iron head (12) and a searing iron handle (13), wherein the explosion-proof isolating power supply (1) is used for outputting two kinds of safe voltages, namely 9V and 24V, to the explosion-proof control box (3) by using a 220V power supply; the infrared transmitting and receiving module (10) is arranged on the welding pedestal (8); an infrared transmitting and receiving sensor is mounted inside the infrared transmitting and receiving module (10), the searing iron handle (13) can be inserted in the infrared transmitting and receiving module (10), so as to block infrared rays, and thus, the connection / disconnection of a heating circuit is controlled.

Description

technical field [0001] The invention belongs to the field of wire welding, and relates to a welding device for wire welding operations in special working occasions, in particular to an automatic power-off explosion-proof wire welding device and a use method thereof. Background technique [0002] At present, in the assembly of flammable and explosive dangerous goods, wire welding is often required. However, the well-known wire welding uses electric soldering irons, which cannot meet the requirements of power-off welding, constant temperature control, and explosion-proof operation. Using the common welding method in the prior art, when conducting wire welding, the temperature of the soldering iron tip cannot be controlled at a constant temperature, and the temperature cannot be accurately controlled. If the temperature is too high, the insulation layer of the wire will be damaged, the flux will volatilize, and the soldering iron will be damaged. The head is oxidized and does n...
