Principle: Water molecule (HHO) decomposes water into oxygen and hydrogen through electrolysis. Hydrogen is combustible. Oxygen supports combustion. These two gases are ignited to form a hydrogen-oxygen flame. In layman’s terms, “water turns into fire”

Use a hydrogen-oxygen flame welding machine to weld the coil lead wires of electronic devices such as motors, motors, and transformers.

working principle:
Water is composed of hydrogen and oxygen. In a specific electrolytic cell, water can be decomposed into hydrogen ions and hydroxide ions. The hydrogen ions move to the cathode to generate hydrogen gas, and the hydroxide ions move to the anode to generate oxygen. Hydrogen is a fuel. Oxygen can be used to support combustion. It can be ignited by a specific hydrogen-oxygen flame gun to form a hydrogen-oxygen flame, which can quickly weld the enameled wire.

Enameled Aluminum Wire VS Enameled Copper Wire

Winding wires used in electrical equipment are usually called magnetic wires. In other words, “magnetic wires are used to exchange electrical energy and magnetic energy.” Magnetic wire is roughly divided into enameled wire (insulation coated) and coated wire (fiber/film insulation) and their combinations. The two types of magnetic wires and their performance are very different. ASTM (American Society for Testing and Materials) B193, no more than 0.017241 ohm (square millimeter/meter), the film or coating should meet the latest version of ANSI, ASTM or NEMA applicable standards, and modify the specified resin. The modified resin is Chemically changed resin, or containing one or more additives to retain the basic chemical characteristics of the original resin to enhance certain performance or application characteristics, the coated conductor needs to meet all the required test requirements of the appropriate NEMA standard (UL certification project) .

Standards Of Enameled Wire includes
1）IEC 60317 for Europe
2）JIS C3202 for Asia
3）NEMA MW 1000C (inch) or NEMA MW 1000C metric (mm) for North America

Compared with general round wires, flat enameled wires have the following advantages:
Higher floor area ratio and better use of space: The high conductor density enables coils and components of the same size to achieve higher efficiency, save materials and reduce costs.

The current mainly passes along the copper-clad aluminum wire on the surface of the wire, which is called the skin effect. The higher the frequency, the more obvious it is. The copper-clad aluminum wire uses this feature to save material. But its resistivity is slightly higher than that of pure copper wire, and the resistivity is also different with the thickness of the copper clad.

Silver plated copper wire is manufacture with the combination of silver and copper and Silver Plated Copper Electrical Wire is manufactured using grade copper and silver; the industrial standards are always kept into the consideration.

The samples for the dielectric strength test are also twisted pairs, and the number is 5 pairs. During the test, the voltage was applied at a boosting rate of 500V/S until breakdown, and the voltage at the time of breakdown was recorded. The requirements for dielectric strength in the NEMA MW1000 standard will vary according to different wire diameters, different paint film thicknesses, and different enameled wire types.

1. Conductor resistance ¡ª The resistance of a conductor is proportional to its length and inversely proportional to its cross-sectional area.
2. Conductivity¡ªBased on the resistance 1/58ohm (0.017241 ohm) of a standard soft copper wire with a length of 1m and a cross-sectional area of 1mm2 at 20¡æ, it is called 100% conductivity. The greater the resistance, the lower the conductivity, and the two are inversely proportional.
3. Bending resistance¡ªfix one end of the single wire, add weight to the other end to make it vertically downward, and then bend it back and forth 180 times until the wire breaks. The more bending times, the stronger the bending resistance.
4. Tensile breaking force¡ªthe maximum load weight or force applied to the specimen to break it during a tensile test.
5. Tensile strength¡ªthe breaking force per unit area to bear when the sample is broken during the tensile test.
6. Elongation ¡ª the ratio of the length of the sample after being stretched until it breaks to the original length at the specified standard distance. Conductors have different impedances at different temperatures.
Generally, 20¡ãC or 25¡ãC is the standard. The higher the temperature, the greater the impedance.

Enameled wire is a main type of winding wire. It is composed of a conductor and an insulating layer. After the bare wire is softened by annealing, it is painted and baked many times.

General purpose enameled wire (ordinary wire): Mainly used for winding wires in general motors, electrical appliances, instruments, transformers, etc., such as polyester enameled wire and modified polyester enameled wire.
