Note: Soldering 2 electrical wires to copper buss bar

Objective:

Soldering two copper wires to pre-installed turrets on a copper buss bar

End Product:

bus bar

Equipment:

Ambrell 1 kW induction heating system, equipped with a remote workhead containing one 1.2μF capacitor. An induction heating coil designed and developed specifically for this application.

Materials:

Solder dipped copper/nickel buss bar, 2 tinned stranded copper wires, brazing stick

Temperature:

446 °F (230 °C)

Frequency:

230 kHz

Testing:

A four-turn split helical coil is used to solder the buss bar assembly. The 2 copper wires are applied to the turrets and power is applied for 30 seconds. The brazing stick is fed by hand to the heated parts and the braze flows evenly, creating the joint.

Benefits:

Induction heating provides:

  • Reduced solder time

  • Even distribution of heating

  • Joint to joint consistency
