SUMMARY OF THE INVENTION INVENTION

The primary purpose of this invention is to provide an 65 FIG. 1 is the routing diagram for a prior art oxy-hydrogen extraction installation for hydrogen and oxygen which can flame welding machine. It is to use ordinary alternating be applied to the oxy-hydrogen welding machine. It is current 10 and to be depressed through transformer 11, using

commutator 21 to commutate it into direct current as the directly gets into storage tank 40 through electrolytic cell 30 electrolysis power for electrolytic cell 30's use. Inside of and in which the gas and liquid are segregated. In which electrolytic cell 30, there is an electrode plate 31 to resolve oxygen and hydrogen again gets into mixing tankS0 through water into hydrogen and oxygen, conveying it into storage condenser 51. In contrast with partial composition indicating 40 for storage and to control its discharge via gas valve 61 diagram on diagram 7, the mixing tank 50 is divided into 3 for welding gun 60's use. As the electrolysis electric pres chambers; they are water erasing chamber 53 for removing sure is about 1.5 to 3 voltage and the alternating current 10 moisture from the mixed gases, returning chamber 54 and is of high electric pressure at more than 110 voltage while mixing chamber 55. In order to clearly manifest the char using single-polar electrolysis, it is necessary to use trans acteristics of mixing tank 50, the gas inhaling tube 531 and former 11 to lower down the electric pressure. Yet the 10 guiding tube 56 are displayed in enlarged size (there is no transformer 11 only holds 50% of its effectiveness and turns indication of gas valve 61 & 62 in FIG. 7). Oxygen and to be very heavy due to magnetic loss and heat loss for big hydrogen is directed into water erasing chamber 53 through current; nevertheless, it is necessary to use big current to gas inhaling tube 531 to get rid of vapor contained in the generate large volume of electrolysis gas. For all these mixed gas, then oxygen and hydrogen is output as fuel reasons, the commutator 21 needs to be big and the area of 15 through exhaust outlet 532. Since it is pure mixed gas with electrode plate 31 also needs to be enlarged, which make the oxygen and hydrogen, the combustion point is high and heat whole machine heavy and unmovable. contentis low with highest flame temperature around 3640° Furthermore, the conventional way is to use single storage C.; there is a gas sharing outlet S33 installed in water erasing tank 40 for collecting gas, which makes the electrolysis chamber 53 to extract part of gases getting into returning liquid prone to overflowing into storage 40 and spilling out 20 chamber 54. There is a guiding tube 56 installed between of welding gun 60 through gas valve 61 to result in the returning chamber 54 and mixing chamber 55, one end of biggest drawback for the uncontrollable flame temperature which is dropping downward to the bottom of returning of welding gun. Taking the mixed gas of oxygen and chamber 54 and the other end of which is buried into hydrogen as fuel, which contains low heat with high flame carbohydrate dissolvent 70 inside of mixing chamber 55. temperature at 3640° C., it is possible to lower the flame 25 Oxygen and hydrogen gets into mixing chamber 55 through temperature and heighten heat content to alternate fuel guiding tube 56 and combined with carbohydrate dissolvent composition through putting carbohydrate dissolvent into 70 and alters the molecule composition or structure to get storage tank 40. Nevertheless, different carbohydrate dissol different fuel traits. There are carbohydrate dissolvents 70 vents will generate different flame temperature and heat that can be used like acetone, alcohols or volatile oils, which content. In general, the storage tank 40 with different car 30 are with different combustive temperature and heat. There bohydrate dissolvent needs to be replaced. However, the are two sorts of fuels being guided into welding gun 60; one flame temperature turns to be invariable once being is drawn out from water erasing chamber 53 directly to installed, which is pretty inconvenient. welding gun 60 through the 1st gas valve 61, which is a This invention provides a way, by using a storage tank mixed gas with oxygen and hydrogen in a high combustive matching mixing tank, to improve the drawback of the prior 35 temperature and low heat. The other is drawn out from art. Referring now to FIGS. 2(a)-(e) and 3, the storage tank mixing chamber 55 to welding gun 60 through 2nd gas valve 40 is shown connected on top of electrolytic cell 30. The 62, which is a gas combined with carbohydrate dissolvent in electrolytic cell 30 is composed of several pieces of elec a low flame temperature and high heat. To control the trode plates 31 which are lined in a parallel row. Each discharge ratio through gas valve 61 & 62, the flame electrode plate 31 is stuck to a heat dispersing board 32, the temperature can be adjusted within the range of 800° to gap between two dispersing board 32 is divided by a insulate 3640° C.

The mixing joint 301 individually with electrode plate 31 in the most tank 50 itself also has protective function, eg: if there is a Outer layer, a multi-polar composition with connection in drawing occurred, the oxygen and fuel is scarce inside of Series and a electrolytic cell 30 without cover are formed. 50 mixing chamber 55 which would be burned out in a With reference now to FIGS. 4 and5(a)-(d) also, the storage minute-this is so called liquid extinguishment. The inner tank 40 is shown closely fixed on top of electrolytic cell 30 pressure generated within a minute would thrust dissolvent and circulated with upper cover 38 through gas intake 401 70 into guiding tube 56 to hinder the fuel gas from continu so that the electrolysis liquid can be complemented directly ously entering in the meantime to alleviate the pressure as to through storage tank 40 with no need of opening electrolytic 55 avoid mechanical damage and reach the goal of extinguish cell 30. After getting through electrolytic cell 30, the elec ment and safety protection.

trolytic liquid should be directed into filtering tank 41 for Please refer to FIG. 8, which is the indication figure for filter through exhaust outlet 402. The filtering tank 41 is the multi-control switch of this invention. The pressure connected with lower cover 39 and somewhere appropriate inside of storage tank 40 is rather high, which could cause on top of which there is a row of rejecting outlets 411 and 60 danger easily. In order to provide safety measures, there is a filtering net 412 installed. The residue filtered out from the a multi-control switch 43 installed to monitor the pressure electrolysis liquid will be rejected through rejecting outlet inside of storage tank 40. It is composed of a micro-active 411. The liquid after electrolysis will be guided back to Switch 431 and a limitation switch 432, which are individu electrolytic cell 30 for recycling use.
