1. What is oxyhydrogen plasma welding machine
Oxyhydrogen plasma weldingmachine, also known as oxyhydrogen multifunction plasma welding and cutting machine, is a kind of portable multi-function plasma welding, cutting, high-energy flame heating equipment. It is made up of plasma generator power supply, shot gun, electrical cable and related accessories. Its weight is just 9kg.
2.The principle of oxy-hydrogen plasma welding machine
The inner nozzle of torch (anode) and electrode (cathode) produce electric arc to make their water evaporate first and then produce ionization, form the plasma state of hydrogen ion, oxygen ion and oxyhydrogen ion. Because of water in shot gun will become gas state from liquid state and then become plasma state, pressure goes up and will be bigger than outside atmosphere. So that plasma erupt from shot gun in terms of plasma beam, its temperature is up to about 8000°C, therefore non- flammable material can be cut, welded, brazed and other forms of flame processing.
Oxyhydrogen plasma welding machine does thermo mechanical processing (cutting, welding, brazing, quenching, spraying, heating, shaping, etc) on metal with thickness of more than 0.3mm by the safe, convenient, efficient, multifunctional, environmental friendly and energy saving ways of producing plasma from vapor. This is an epochal innovation in the metal processing history.
3. The Main Features of Oxyhydrogen Plasma Welding Machine
One set of plasma welding machine has many functions, such as welding, brazing, cutting, heating, quenching and etc.
(a) It can cut and weld any non-flammable materials, including stainless steel, high-alloy steel, aluminum, titanium, brick, concrete, ceramics and other materials.
(b) Oxyhydrogen plasma welding machine can replace or save the following tools efficiently: cutting board, gear cutting, hay cutter, electric saw, blow lamp (valve), oxygen welding gun, hot-air gun, welding inverter or pressure regular, laser cutter and other metals.
(c) Precise cutting (kerf is not over 1mm) is often used to make template, french curve and plug board.
(a) No need air compressor, transformer, gas cylinder and other auxiliary appliances when using. The machine is just 9kg in total and has dedicated portable shoulder bag for welder.
(b) The medium for using is only liquid (water or alcohol with 50% content). Using water when cutting and using dilute alcohol when welding.
(c) Oxyhydrogen plasma welding machine just need power supply with 110V or 220V, don’t need 380V.
(d) Oxyhydrogen plasma weldng machine can operate in the enclosure space with no ventilation (office, house, pipe, mine, well, tunnel, basement and etc.)
(3) Economical Usefulness
Economical usefulness mainly shows in saving energy. If compared with the equipment which has welding transformer, oxyhydrogen plasma welding machine can save ten thousands of expenses for you in a year. If it is used in the wild, it can save more considerably, like fuel costs of generators. (It doesn’t include that the generator with 4Kw is several times cheaper than the generator required by electric arc welding machine.)
(4) Environmental Protection
Oxyhydrogen plasma welding machine has realized the breakthrough in flame processing technology of environmental welding, environmental cutting and etc. Ionized vapor molecules produce plasma beam to block raised metal powders, cool them in a minute and stop them enter into welders’ respiratory organ.
Working in this way, processing materials won’t burn and oxidize so that it has a positive significance on environmental protection. Because it has replaced propane, acetylene, liquefied gas and other polluted gas.
The traditional gas, which has used propane, acetylene and liquefied gas as the industrial gas to weld and cut, is the cylinder high pressure filling, so it is easy to appear dangers of leakage, poisoning, fire-catching, explosion and etc. On the contrary, oxyhydrogen plasma welding machine just uses water as the raw material, so what it expends is water and power, and what product it generates is also just vapor, no poisonous substance will be generated. In a conclusion, it is a very safe and high-efficient cutting equipment.
(a) The temperature of the flame produced by oxyhydrogen plasma cutting machine can be up to 8000°C, which is 3 times higher than propane’s, 2.5 times higher than acetylene’s. So that it can work high-efficiently.
(b) The processing metals deform less because of concentrated flame and less heating area.
(c) It is able to form efficiently antirust oxide layer ( weld joint won’t get rusty) in the section of metal processing.
Oxyhydrogen plasma welding machine can ensure to keep serving for you at its best every day and every hour.
