Enamelled wire requires a bit of assistance; that's right, it needs the help of an enamelled wire welding machine. Also known as a hydrogen-oxygen flame enamelled wire welder or ultrasonic wire bundle welder, this machine uses hydrogen-oxygen flame or ultrasonic technology to weld and fuse the lead wires of coils in electronic devices such as motors, engines, transformers, etc.

The hydrogen-oxygen flame wire-winding welder operates using only water and electricity to generate the flame required for welding, eliminating the need for additional gas cylinders, making it convenient to use. Compared to traditional wire-winding welding, it does not require stripping the paint, and due to the high flame temperature, excess leads can be burned off directly, thus maintaining a flat welding surface.
