Therefore, the object to be welded is not contaminated with smoke. Further, in the case of fusing an iron plate or the like, the amount of generated heat is small, so that distortion due to heat is small, and the straightness of the flame is good, so that the fusing speed can be increased. Further, since the amount of heat generated at the time of combustion is as small as about 1/3 of the acetylene gas, the hot atmosphere at the work site can be greatly improved.

Claims (4)

[Claims] 1. A storage tank filled with an electrolytic solution, an electrolytic tank connected to the storage tank via a conduit and supplied with the electrolytic solution in the storage tank, And a gas introduction pipe for allowing the hydrogen / oxygen gas and the electrolyte solution to flow into the storage tank, and a large number of the electrolysis tanks are stacked in the thickness direction with spacers interposed therebetween. An electrode plate group formed with a first distribution port through which the electrolyte flows in the stacking direction, and a second distribution port through which the hydrogen / oxygen gas and the electrolyte flow, and both sides of the electrode group. A fixed left and right plate, and an intermediate plate disposed between the left and right plates. The left and right plates include one end of the conduit and the gas One of the introduction pipes One end of the gas introduction tube is fixed to the intermediate plate, and hydrogen generated in the electrolytic cell is fixed to the intermediate plate.
The hydrogen / oxygen gas generator is characterized in that the oxygen gas flows out of the electrolytic cell through each of the gas introduction pipes. 2. A Peltier cooling device is provided in a discharge path of the hydrogen / oxygen gas flowing into the storage tank, and the hydrogen / oxygen gas is cooled through the Peltier cooling device and discharged to the outside. 2. The hydrogen / oxygen gas generator according to claim 1, wherein the hydrogen / oxygen gas generator is configured as described above. 3. The other end of the gas introduction pipe is connected to the storage tank, and a circulation path is formed in the storage tank to circulate through a drive pump. The hydrogen / oxygen gas generator according to claim 1 or 2, further comprising a filter. 4. An end of a circulation path connected to the storage tank and returning the filtered electrolyte into the storage tank is connected to a discharge pipe for discharging hydrogen / oxygen gas from the storage tank through a pipe connection member. 4. The hydrogen / oxygen gas generator according to claim 3, wherein the hydrogen / oxygen gas is connected and moves in a direction opposite to an inflow direction of the electrolytic solution filtered from inside the storage tank.
