Twin Hot Tip Weld Head

Two spaced weld heads 10 and 12 can be used to strip the insulation off a portion of wire 14 and weld the underlying metal core of 14 to terminal 16 with a single weld pulse 18.

Weld heads 10 and 12 are joined together by high-impedance interconnection 20. Heads 10 and 12 are connected in series with the source of pulse 18. To weld wire 14 to terminal 16, tips 10 and 12 are positioned on wire 14, as shown, and pulse 18 is applied.

This heats tips 10 and 12 causing them to melt the insulation of wire 14 through to its metal core. Once tips 10 and 12 are through the insulation they contact the metal core of wire 14, the core forming an electrical connection between the tips. Current produced by pulse 18 now flows through wire 14 between tips 10 and 12 instead of through interconnection 20 shunted by wire
14. This heats the wire portion in the path between tips 10 and 12. Such causes the insulation in that portion to melt and expose the heated metal core. With the core exposed, it becomes welded to terminal 16 as current continues to pass through it.
