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.
Fill with Ultratane Butane
Unit operates on butane gas and creates infared heat effectively
by the use of a catalyst. Use only Master Ultratane butane with
your Ultratorch. Make sure on/off lever is in "off" position before
filling. To fill, press nozzle of butane can down onto refill opening.
Unit is full when gas overflows refill opening. Check window for
fuel level.
