Principles of Operation
This product uses a catalytic gas reaction sys-
tem. The special catalyst contained in the tip is
preheated with a butane flame. The preheated
flame is extinguished when the shutter is closed
over the ignition vent.
Butane gas continues to flow over the preheated
catalyst generating infrared heat which is either
conducted through the soldering iron tip or
passed through the heat tip as hot gas.
