Micro flame welder, also named, hydrogen oxygen flame welder or water welding machine, is an ideal, safe, reliable, effective and environmental way of welding metal wires, enameled(lacquered)copper wires, melting and processing gold, platinum jewelry or other metal ornament, sealing small glass bottles or quartz glass tubes and so on. Working principle of micro flame welder is electrolysis of water produces mixed hydrogen and oxygen gases.Ignite the gases in the flame torch tip, and use the clean, still and concentrated flame for micro welding, soldering, melting, car engine carbon-cleaning and so on. Three operators can work simutenously using one 305t 305t belongs to industrial type and can bear heavy working load.There is one electrolytic cell and one feeding cell inside the machine.And also it has an independent flashback arrestor, flame torch with anti-flashback device, and led digital screen display which s hows gas output and electrilytic current clearly. And there is an current-adjusting rotary valve, which can be adjusted to keep the machine working all the time without auto-stop, and also there is water-leaking alarm which alarms once waterline is near the feeding-line. Applications: Polishing uneven and hard-to-reach area of acrylic products and acrylic parts without any residue, such as acrylic sheets, signs and acrylic lettering Welding metal wires, especially enameled copper wires in electric motors and transformers Melting and fusing of gold, silver, platinum, and their spots and face welding Sealing small quartz glass bottles and ampules Spot annealing of small parts in all metals Welding, cutting and drilling of very thin metals Welding copper tubes Car engine carbon cleaning Produce hho gases 300 liter/hour automatically Size: 67cm*31cm*54cm Weight:22kg
