Soldering with micro flame

In microflame brazing, heat is generated by a hydrogen-oxygen flame. To obtain a uniform flame and heat distribution, the fuel gas is obtained by electrolysis. Hydrogen escapes at the cathode and oxygen at the anode in a 2:1 ratio. By varying the applied voltage, the amount of gas produced can be continuously controlled. The fine pointed flame has a temperature of 2000 - 3000 °C. The temperature can be lowered by adding alcohol. The additional oxygen consumption during alcohol combustion creates a reducing zone in the flame and removes oxide layers on the soldering surfaces. As a system integrator we use the SPIRFLAME® gas generators from Spirig.
