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.

An electrical motor is one kind of machine which is used to change the energy from electrical to mechanical. Most of the motors work on the principle of interaction among the electric current as well as the magnetic field within a wire winding. This can generate force in the form of shaft rotation. These motors can be powered with DC or AC sources. The DC sources are batteries whereas the AC sources are inverters, power grids, generators. A generator is mechanically similar to the motor but works in the reverse direction by converting the energy from mechanical to electrical. An electric motor can be built with the rotor, stator, air gap, windings, bearings, & commutator. The classification of motors can be done with considerations like the type of power source, construction, motion output type, and applications. This article discusses what is a motor winding, types, and its calculation.

Enameled wire is the most widely used electromagnetic wire in the production of low-voltage products. A key performance requirement of this electromagnetic wire is the continuity of the paint film, which is to check the number of pinholes in the paint film under a certain length. When checking the number of pinholes, use a professional paint film continuity tester. The fewer the number of pinholes, the better the paint film integrity of the magnet wire.

Enameled wire is a main type of magnet 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. However, it is not easy to produce products that not only meet the requirements of the standard, but also meet the requirements of customers.
