Principles of Operation

This product uses a catalytic gas reaction system. 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.

Hot Air Vent Catalyst

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

Use only Master Ultratane butane with your Ultratorch. Do not fill gas or store near open flame, heater, furnace or combustible materials. Make sure the unit is cool before re-fueling. Fill gas holding the unit firmly with the refill nozzle pointed upwards and press down. Gas will overflow from nozzle when tank is full.
