Acerca de Little Torch™
¿Cómo reemplazar la manguera del Little Torch?
Hay instrucciones paso a paso, junto con una férula (banda de retención de manguera de latón) y una herramienta de reemplazo de férula que acompañan a todos los conjuntos de mangueras de repuesto. Para obtener instrucciones detalladas, consulte el manual del propietario. Recomendación: Reemplace las mangueras cada cinco años.
¿Cuáles son los números de pieza de los conjuntos de mangueras de repuesto de Little Torch?
Dependiendo de los accesorios de la manguera, necesitará el siguiente conjunto de manguera:
- 13254-4-8 Conexiones de manguera estándar «B» 9/16″-18
- 13254-5-8 Conexiones de manguera australianas
- 13254-6-8 Conexiones de manguera británicas
- 13254-7-8 Racores de manguera europeos
Cada conjunto de manguera incluye una manguera de oxígeno de 8 pies (verde), una manguera de combustible de 8 pies (roja), dos casquillos de manguera, una herramienta de engarzado y un manual. Recomendación: Reemplace las mangueras cada cinco años.
¿Se puede limpiar el orificio de las puntas Little Torch?
Si el orificio está obstruido por el fundente, a menudo se pueden limpiar hirviendolos en agua durante aproximadamente 10 minutos. Otros métodos utilizados para limpiar las boquillas secas implican el uso de un limpiador a vapor tipo joyero o un limpiador ultrasónico.
¿Por qué es difícil encender o mantener encendida mi boquilla de tamaño Nro 2?
Por lo general, esto se debe a presiones de gas excesivas. Se recomienda un máximo de solo dos psi de presión de salida para ambos gases y el uso de una llama abierta hace que encender la pequeña llama sea mucho más fácil.
¿Para qué se utilizan las puntas de llama gemela?
Las puntas de llama gemelas flexibles se pueden utilizar para calentar ambos lados de un objeto. Pueden acelerar el proceso de brazing y proporcionar un calentamiento uniforme para flujos de soldadura completos y más uniformes.

What are the applications for the multi-flame heating (rosebud) tips?
The rosebud tips may be used where a larger, more widely dispersed flame is needed for brazing, soldering or heating. They are used predominantly in the jeweler industry for annealing, reticulation and casting of gold or silver.
Both the acetylene and propane models can cast up to three ounces of gold and silver. These tips are also used for enameling and plastics polishing.
Note: Heating tips are not for use with disposable oxygen cylinders.
What fuel gas will work with the Little Torch?
The Little Torch may be operated with most commercially used welding gases including acetylene, propane, hydrogen and propylene. It may be used with city gas (natural gas) if the minimum pressure required for the tip is sufficient.
Caution: Most city gas lines only produce less than one psi.
Which fuel gas should I use with my Little Torch, acetylene or propane?
Most Little Torch operators use either acetylene or propane with each offering specific advantages and disadvantages.
Acetylene produces a very concentrated, pinpoint high-temperature flame (approximately 6,000°F) whereas the other gases tend to spread the head produced throughout the outer flame.
The acetylene flame produces soot during combustion and the propane 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.
Propane gas is heavier than air and will fall to the floor and may collect in low spots thereby creating a potentially combustible hazard.
Can the gas valves be replaced if they are damaged or worn out?
Yes. The complete torch valve assembly may be replaced for oxygen and fuel gas. Using an open-end wrench, remove the valve assembly from the torch body. There is a white packing ring (7348) under the valve that should be replaced. Green identifies the oxygen valve assembly (7345) and red identifies the fuel valve assembly (7346).
Does my Little Torch require any adaptors to fit my cylinder regulators?
For most regulators, adaptors are not required. The Little Torch hose assemblies have standard “B” 9/16-inch welding hose connections and attach to most industrial welding gas regulators.
Where can I use the Little Torch Caddy Kits’ cylinders?
Individuals using the cylinders inside should contact their insurance carriers and research fire codes for their locations.
How long will the oxygen and fuel gas last in disposable cylinders?
The Little Torch for Disposable Tanks Kit (23-1014) is available for use with disposable propane (or propylene) and oxygen cylinders. Disposable propane cylinders have 7.50 cfh of gas. Disposable oxygen cylinders have 1.05 cfh of gas.
This means that a No. 5 tip (12-1401-05) at 2.58 cfh propane and 3.1 cfh oxygen consumption would use up an oxygen cylinder in 20 minutes and a propane cylinder in three hours.
Note: Disposable oxygen and fuel cylinders may be purchased at your local hardware or gas distributors.
