The Bernzomatic Brass Torch, model UL2317, is a handheld device designed for various heating applications, primarily utilizing propane fuel. Its core function is to produce a controlled flame for tasks such as brazing, light cutting, and welding. The torch is engineered for ease of use and portability, connecting directly to Hand Held Propane Cylinders (DOT-39 or TC-39M).
The Bernzomatic Brass Torch operates by igniting propane gas, which is released through a control knob and directed through a nozzle to create a flame. The device is designed to provide a consistent and adjustable flame, making it suitable for a range of tasks requiring heat. The brass construction of the torch contributes to its durability and performance. The torch's primary function is to generate heat for various applications, from hobbyist projects to professional tasks, where a portable and reliable heat source is needed. It is specifically designed to work with propane, a highly flammable gas, and therefore incorporates safety features and warnings to ensure safe operation. The torch's design allows for precise flame control, enabling users to adjust the intensity and size of the flame according to the specific requirements of their task. This adjustability is crucial for achieving optimal results in applications like soldering, heating, and light fabrication.
The Bernzomatic Brass Torch emphasizes user safety and operational efficiency. Before use, users are instructed to read and comply with all warnings and instructions in the manual, familiarizing themselves with the torch's operation. The torch is designed for use with propane only, specifically with Hand Held Propane Cylinders.
To assemble, the valve must first be turned OFF by rotating the control knob in the direction of the arrow until hand tight, without forcing. Then, the fuel cylinder is turned clockwise into the valve body until hand tight, again without forcing. This secure connection is critical to prevent gas leaks.
The torch can be lit with a match or a spark lighter. When using a match, it should be held as shown in the manual, and the valve opened slowly. For a spark lighter, the valve is opened slowly before sparking, holding the lighter at a 45° angle to the torch opening. It's noted that lighting with the valve fully open is difficult. For the hottest and most efficient flame, the inner blue flame of the pencil burner should be adjusted to a length of 1-1/2 to 2 inches. If ignition doesn't occur immediately, the valve should be closed, and the user should wait 5 minutes before attempting to ignite again to prevent the buildup of flammable gas, which could lead to a fireball.
The torch must only be used in an upright position; using it upside down or tilting it too far can cause liquid propane to enter the valve, leading to flaring or extinguishing of the flame. Users are advised to keep a fire extinguisher nearby and always point the flame away from their body, other persons, and flammable objects. It's crucial to ensure no unintended materials are heated. The torch should never be used as a cigarette lighter.
The torch consumes oxygen and must be used in well-ventilated areas, not in confined workspaces or enclosed spaces. When working outdoors, caution is advised on sunny or windy days, as bright sun can obscure the flame, and wind can misdirect it, potentially causing sparks to contact combustible materials.
Users are strongly advised to wear goggles with an ANSI 287.12979 shade lens number appropriate for the operation: brazing and light cutting (3 or 4), medium cutting and light welding (4 or 5), heavy cutting and medium/heavy welding (5-8). Protective gloves should always be worn.
The torch should not be used to heat, mold, or bend plastic sheets, molding, or tubing, nor to remove paint. When working in areas with potential hidden flammable materials (e.g., behind walls, ceilings), the torch should be kept moving in a back-and-forth motion to prevent ignition. Fumes from fluxes, cadmium plating, brass, zinc, and galvanized metal are toxic, so working in well-ventilated areas is essential.
Propane cylinders must be kept away from heat or flame and out of reach of children. Refilling cylinders is illegal and dangerous, with severe penalties. Prolonged exposure to sunlight should be avoided, and cylinders should not be stored near heat sources or in rooms used for habitation. When empty, cylinders should be discarded safely, not thrown in fire, punctured, or incinerated.
Proper maintenance and regular checks are vital for the safe and efficient operation of the Bernzomatic Brass Torch.
Before each use, all parts should be checked for proper function and any damage to component parts. This includes inspecting the nozzle, tube, spindle, body, control knob, and inserted shaft for any signs of wear, cracks, or blockages.
All joints and couplings should be periodically checked for loose connections. With the valve open (but unlit), a soapy water solution can be applied to connections to test for leaks. If bubbles appear, it indicates a gas leak, and the torch must be repaired before further use. A flame should never be used to check for leaks. This test should be performed in a well-ventilated, spark-free area without open flames.
The torch must be cool before tightening or removing the burner head, or before installing or removing accessories. When not in use, the torch should be disconnected from the cylinder. After the torch has cooled, the cylinder and torch should be stored separately and out of reach of children, observing all cautions on the cylinder label.
The torch should never be dropped or abused. If it is leaking, damaged, or malfunctioning, it must not be used. If the torch is dropped, the burner may snap and must be replaced. Unauthorized servicing or modification of the torch construction or the use of unapproved accessories or fuels is strictly prohibited.
Always detach the torch from the cylinder when not in use. When the cylinder is empty, it should be discarded in a safe place.
Regularly review the instructions and warnings to maintain awareness of safe operating procedures and maintenance requirements. This proactive approach helps ensure the longevity and safe performance of the Bernzomatic Brass Torch.
