There are step-by-step instructions and a ferrule (brass hose retainer band) and ferrule replacement tool that accompany all replacement hose assemblies.

This is typically due to excessive gas pressures. A maximum of just 2 psi outlet pressure is recommended for both gases and the use of an open flame makes lighting the tiny flames much easier.

For most regulators no, the Little Torch hose assemblies have standard size "B" 9/16" welding hose type connections and will attach to most industrial welding gas regulators.

If the orifice is obstructed by flux, often times they can be cleaned by boiling them in water for 10 minutes or so. Other methods used to clean dirty tips involve the use of a jeweler’s type steam cleaner or an ultrasonic cleaner.

The Little torch may be operated with most commercially used welding gases including; Acetylene, Propane, Hydrogen, Propylene, Butane, Mapp®. It may also be used with city gas (natural gas) at a minimum pressure of 1 psi at the torch. Caution: Most city gas lines only produce ¼ to ½ psi.

Most Little torch operators use either Acetylene or Propane.  However, both offer specific advantages and disadvantages. Acetylene produces a very concentrated, pinpoint high temperature flame (approximately 6000°F) where as the other gases tend to spread the heat produced throughout the outer flame. The Acetylene flame produces soot during combustion and the LP gases tend to burn much cleaner. Acetylene gas is lighter than air and in the event of a gas leak it will tend to dissipate in the atmosphere with any air flow, where LP gas is heavier than air and will fall to the floor and may collect in low spots thereby creating a potentially combustible hazard.

The single and twin flame tips may all be used with acetylene or hydrogen. Tip sizes 1 and 2 can not be used with LP gases i.e. propane, propylene, Mapp®, butane or natural gas. Sizes 3 through 7 may be used with any fuel gas. Note: Oxygen is required for use with all Little Torch tips as well.

The flexible twin flame tips may be used where both sides of an object can be heated. They can speed up the soldering or brazing process and provide even heating for complete, more even solder flows. The size #3 twin tip is often used by jewelers for sizing rings.

They may be used where a larger more widely dispersed flame is needed for brazing, soldering or heating. They are used predominantly in the jewelry industry for annealing, reticulation and casting of gold and silver. Both acetylene and the propane models are capable of casting up to 3 oz. of gold or silver.

Yes, the complete valve assembly may be replaced for either gas. Using an open end wrench remove the valve assembly from the torch body. There is a white packing ring under the valve that should also be replaced part # 7348. Valve assembly part numbers are as follows: Oxygen (green) #7345; Fuel (red) #7346

Flashback arrestors are devices designed to stop a flashback fire in the oxy-fuel torch system.  A flashback fire is composed of a mixture of oxygen and fuel gas burning back into the torch system.  Flashback arrestors are usually designed with reverse flow check valves built in.  Check valves alone are designed to stop the reverse flow of oxygen into the fuel side or fuel into the oxygen side of the torch system.  Check valves help to eliminate mixed gases in the system to stop a flashback from occurring; however, they will not stop a flashback fire.  Check valves should be used at minimum, in the oxy-fuel system; however, it is highly recommended flashback arrestors be used, especially with casting torches.  Check valves and flashback arrestors may be installed between the regulators and the hoses, or between the torch handle and the hose.  It is recommended that flashback arrestors be installed between the torch and hose for casting operations.
 
 
 

Most welding supply stores will accept empty oxy-fuel cylinders and trade for re-filled cylinders.  Disposable MAPP®, propane, or oxygen tanks may be purchased from most hardware supply stores.  Refillable propane tanks can be refilled or traded for full tanks at most propane gas supply distributors.
