See that Fig. 1 electrolyte adopts ordinary tap water to enter electrolytic cell 1 toward water-supply-pipe 3.5 after liquid gas tank 3 filters, hydrogen, oxygen after being separated by electrolytic cell 1 1.2,1.1 import hydrogen, oxygen air accumulator 3.1,3.2 in the liquid gas tank 3 respectively by the road.In the pipeline that hydrogen is discharged, automatically controlled sprayer 2 is set.Hydrogen and oxygen passes through pneumatic filter 4, dry annealing device 5 respectively, delivers to welding torch 6 generation oxyhydrogen combustion combination reactions, welds.AC power is through silicon controlled rectifier (SCR) 7, and square-wave generator 11 offers electrolytic cell 1.The hydrogen of hydrogen jar 3.1, oxygen jar 3.2, oxygen are delivered to sensor four-way 9 by gas transmission 3.3,3.4 respectively, with Pressure gauge 8, pressure switch 10 UNICOMs, reach and measure and the control integral pressure.Excessive when pressure, relay 10 cuts off the complete machine power supply automatically and quits work, and the hypotony complete machine is connected power up work automatically.Gas pressure is kept within the specific limits.

See Fig. 2, Fig. 3.Adopt 100 overlapping compositions of dull and stereotyped electrolytic cell.Every dull and stereotyped electrolytic cell (see figure 3) has pole piece 1.6, pot shell 1.7, and diameter of bore is φ.Place barrier film 1.8 between sheet, and form cathode chamber 1.4, anode chamber 1.5 in turn.The hydrogen of offering on each sheet pot shell 1.7, oxygen horizontally-arranged tracheae 1.11,1.14 ends are respectively to be communicated with the anode chamber and the cathode chamber 1.4,1.5.Running water after filtering enters in the electrolytic cell through water inlet 1.3, and the hydrogen of energising electrolysis is that positive charge leans on negative pole face (in the cathode chamber 1.4).Oxygen is that negative electrical charge leans on positive pole-face (anode chamber 1.5 in) and respectively hangs oneself blast pipe 1.11,1.12 and 1.14,1.13 and give vent to anger and 1.9 discharge.1.10 be air storage chamber.60 ℃～100 ℃ of electrolyte operating temperatures.

See Fig. 4, running water injects through water intaking valve 3.7, crosses device 3.6 through ion exchange resin and enters in the flow container 3.14, in water-supply-pipe 3.5 is pressed into electrolytic cell 1.Liquid is irritated and is established microcircuit control water gauge 3.13 in 3.14.Irritate the moisture storage capacity situation with indication and control liquid.Electrolytic cell 1 is isolated hydrogen, oxygen and is imported hydrogen air accumulator 3.1,3.2 respectively.Drying agent 3.9 dryings.After hydrogen filtered by glass fibre, at the bottom of moisture content was deposited in jar, aperture entered flow container 3.14 at the bottom of jar.If during welding operation, operator's error causes tempering, has increased system pressure, and for the safety of complete machine, explosion takes place burst disk 3.11, reaches the purpose of moment release.3.10 be the burst disk gland.3.8 be water intaking valve burst disk gland, 3.12 is dividing plate.

See Fig. 5, dried hydrogen is sent into the air inlet 2.5 of automatically controlled sprayer 2 and is reached fog-spray nozzle 2.8 through gas transmission joint 3.3.When not welding, spraying system pressure reaches poised state.When welding, the gas outlet pressure of fog-spray nozzle 2.8 descends, and forms pressure reduction, pressure and by suction pipe 2.3 effect what scaling powders 2.2 and by shower nozzle 2.8 scaling powder is brought in the hydrogen.Under air inlet 2.7 pressure effects, hydrogen reaches the purpose that hydrogen is carried scaling powder secretly through sprayer 2 inwall pipelines with the scaling powder ejection.Hydrogen is outwards carried toward gas outlet 2.6.Microcircuit 2.4 is controlled opening and closing of sprayer 2 inner joint valves 2.7.Control valve doorway size realizes the purpose by welding process requirement adjusting scaling powder addition.

Adopt husky stamen filtering gas among Fig. 1 in the pneumatic filter 4, the dry annealing device adopts standard SA-Y1 type dry type post L alkynes temper device, has flame-out non-return, function such as cut off source of the gas, reset.
