How to solder enameled wire for motors?

Enameled Wire Copper Wire Welding
Hydroxide flame motor enameled and lead-in wire welding advantages:
Flame is concentrated, welding speed is faster than other gases. The flame is carbonless, does not change the steel and flexibility of the workpiece. Easy to operate, without any gas cylinder, just water and electricity. Environmental protection and energy saving, without any waste gas and smoke emission.
Welding of motor enameled wire requires attention to the following steps:

1. Stripping the enamel layer: use wire stripping pliers or stripping knife to strip a small section of the motor enameled wire of the enamel layer, exposing the internal copper wire. It should be noted that the stripped length should not exceed 1cm, so as not to expose the copper wire to air oxidation, affecting the contact quality.
2. Clean the surface of the copper wire: Before welding, the surface of the copper wire should be cleaned with alcohol cotton balls or detergents to remove the oil and oxides on the surface to ensure the welding quality.
3. preheat: motor enameled wire of copper wire diameter is generally thin, welding needs to be preheated, so as not to excessive welding temperature damage to the copper wire or burn the insulation layer. You can use a soldering iron or soldering station for preheating, the temperature is generally controlled at about 200 ℃. 4.
4. Soldering: After preheating, place the solder wire on the copper wire and use a soldering iron or soldering station for soldering. Soldering time is generally no more than 5 seconds, so as not to overheat and damage the insulation.
5. Insulation: after the welding is completed, you need to use insulating tape or insulating sleeve to insulate the welding place to ensure the safety and reliability of the motor enameled wire.

It should be noted that the welding of motor enameled wire needs to be very careful so as not to damage the insulation layer or affect the normal operation of the motor. It is recommended that people who do not have the relevant skills or experience should not arbitrarily carry out welding operations, and should seek the help of professional and technical personnel.
Conforms to enameled wire welding standards, eliminates the need for lacquer coating process, secure welding joints without false welding, stable flame concentration, small heat-affected area, small resistance deviation. No risk of deflagration and poisoning when replacing high-risk gas cylinders such as oxyacetylene. Adding water and electricity to produce gas, reducing fuel costs than conventional gas (acetylene, liquefied petroleum gas, natural gas) cost savings.
