Copper wire welding special solder | No residual flux | Welding solution for transformer distribution box and motor

In electrical equipment and power electronics manufacturing, the welding quality of copper wire (round wire or flat wire) square wire directly determines the conductivity efficiency, insulation safety, and service life of the whole machine. Traditional soldering materials often face pain points such as dull and brittle solder joints, residual corrosion of solder flux, and joint breakage after prolonged storage. This not only increases cleaning and repair costs, but also poses a risk to equipment operation. In response to the actual process requirements of high and low voltage transformers, distribution systems, voltage regulators, and motor production lines, we have launched a specialized solder for copper wire welding. With the core advantages of "bright and reliable, high-temperature self volatilization, and long-term stability", we provide a standardized solution for industrial welding that is free of cleaning and has a high yield rate

Dongguan Bonte produces copper wire flux BT-706, which is suitable for soldering flat and round copper wires;

Solder is bright, reliable, and hard; Wuxi tip, soldering does not explode;

Under high temperature conditions, it evaporates on its own without residue, and the solder joints remain firm even after prolonged storage.

This product has been widely used in the following core production line links, achieving "one material for multiple uses and stable output":

High and low voltage transformers&isolation transformers: winding leads, tap connections, interlayer transition welding to ensure insulation withstand voltage and temperature rise control

Power/lighting distribution box: Copper bar overlap, fast interconnection between grounding wire and control wire, improving assembly efficiency and seismic reliability

High power/high-precision fully automatic voltage regulator: The sampling point of the voltage regulating coil is precisely welded to the power terminal to ensure voltage response accuracy

Manufacturing of various types of motors: stator/rotor winding leads, commutator terminals, fixed welding of lead wires, suitable for high-speed winding and automated offline processes

Whether it is continuous operation on a fully automated production line or flexible production with multiple specifications in small batches, stable tin output, consistent molding, and controllable yield can be achieved.

Different wire diameters, flat wire specifications, welding temperature curves, and welding activity requirements all affect the final forming effect.
