Hot Crimping
Hot Crimping is a technique used to burn away the enamel on coil wire before welding it the wires together as well as with the crimp which is around the wire. A high frequency inverter at high current is typically used for this type of application, with the inverter set to dual pulse mode.
Having the inverter set in dual pulse mode means there are two welding pulses; the first which will heat up and burn away the enamel on the wire; the second for welding the wire to the crimp.
The inverter will be accompanied by a high force weld head to exert enough force to compress the wire and the crimp during the weld.
