Induction heating is used to apply heat to mating components to melt a filler metal placed around or between the joint which then coats and bonds the components in the region of the joint. Commonly used filler metals are tin-lead, tin-silver, and tin-zinc. Induction heating can eliminate cold joints, protect insulation materials in close proximity to the joint since they are not heated by the induction field, and in some case even provide a stirring action and promote solder flow in connectors. Soldering is used in many joining applications but is used most often for high quality electrical connections which can then resist joint degradation and loss of conductivity due to corrosion or vibration, in operations where non metallic components are joined to metals.
HS 2500R2 w/foot pedal power control used to solder high amp cables into solder cups. U shaped coil gives high heat input required and solder is fed manually w/heat as needed.
A recessed connection is quickly soldered with a U style coil and preplaced solder rings using a HS 2500R2C and a timed cycle.
Large terminals are soldered much more quickly with a soldering iron, while leaving the operator hands free.
A split style coil with pneumatic open and close provides precise heat input to microwave connectors on an automatic machine.
A steel nipple is soldered to a steel cup in two seconds with a 2500 watt unit.
Soldering coils are available in U type, solenoid type, concentric or multiple position. They can be shaped to the part or encapsulated for quick fit into automated machine fixtures.
