Current step supply for heating conductor for sticking long parts - has measurement and control circuits controlling current according to heating conductor resistance

摘要

A current step supply for a molten adhesive coated heating conductor contains a mains transformer and an on/off switch forming a circuit for the flow of current through the heating conductor. In addition to the current step circuit (15) there is a measurement circuit (20) which detects the resistance value of the heating conductor (2) connected to the supply (1). A control stage (9) between the measurement and current step circuits controls the current in the current circuit according to the heating conductor resistance. USE/ADVANTAGE - For use in sticking long parts. Current supply is partic. suitable for processing coated heating conductor.
