Abstract
A hand held sealer compresses and welds tubing intermediate a pair of jaws, which jaws also serve as the plates of a variable capacitor of an Rf resonant circuit. The flow of power intermediate the jaws generating the heat applied to accomplish the weld is a function of the spacing of the jaws, whereby the applied power is regulated to weld but not destructively melt the tubing.
