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.

Chrome Plated Copper Base Nickel Plated Iron Plated

Evaporated

Gas

Tinned

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.

Ignition Instructions

1.Be sure the exhaust opening is positioned upward. Keep hands and combustibles clear of exhaust opening and tip housing to avoid burns or fire.

2.Set the gas Control lever in the middle of the + and -. (In cold places or soon after refueling, move lever towards + and in hot, towards -.

3.Push the ignition lever upward slowly until it clicks. After several seconds, the window becomes red and the catalyst starts to react without a flame inside. If the unit did not ignite, push the OFF button and repeat.

4.Adjust tip temperature with the gas control lever.

5.To turn off, push GAS OFF BUTTON. Check window to make sure the unit is off.

Use as a Soldering Iron or Heat Tool

1.Loosen knurled nut to remove tip and tip housing.

2.Replace with soldering tip or hotblow tip and re-install tip housing onto unit.

DO NOT TRY TO IGNITE WHEN SOLDERING OR HEAT TIP IS DISMOUNTED. THIS COULD LEAD TO AN IGNITION PROBLEM.

To Replace Ejector

Change ejector unit when gas does not flow, ceramic burner is broken or used up after a certain amount of time, etc.

TO REMOVE

1.Remove a soldering/heat tip by loosening the knurled nut.

2.Insert a bar into the hole on the ejector and turn clockwise. The ejector unit will come away.

TO REMOUNT

1.Replace with new ejector unit and insert a bar in the hole on ejector and turn counter-clock- wise to tighten.

2.Replace a tip and tighten the knurled nut. (fig 3)

Storage of Your Ultratorch Heat Tool

1.Allow unit to cool and put protective cap on for storage.

2.If your unit is not going to be used for awhile, store in the following manner. Store in proper location avoiding elevated temperatures and away from children.

3.Leave tank approximately 1/2 full so lubrication of fuel pickup filter stays wet.

4. Set flow control valve at mid setting.
