The Bernzomatic Trigger-Start Torches, including models TS4000, TS7000, TS8000, and BZ4500HS, are designed for various heating and soldering applications. These torches are intended for use with hand-held gas cylinders specifically designated for torches, providing a portable and efficient heat source. The primary function of these devices is to produce a controlled flame for tasks such as brazing, light cutting, medium cutting, light welding, medium/heavy welding, and other heating operations.
The torches operate by igniting gas from a connected cylinder to produce a flame. The TS7000 and TS8000 models feature a flame adjustment knob (1) that allows users to regulate the flame size, offering greater control over the heat output. The TS4000 and BZ4500HS models do not include this flame adjustment knob, providing a more straightforward operation. All models are equipped with an ignition button (2) for easy lighting and extinguishing of the flame. The ignition button can be set to "LOCKED" to prevent accidental ignition and to "UNLOCK" for operation. A flame lock button (3) is also integrated into the design, allowing the user to maintain a continuous flame without continuously depressing the ignition button. This feature enhances convenience for tasks requiring prolonged heating. The torches incorporate a built-in regulator that controls pressure and helps reduce the risk of pulsating or yellow flames, especially when the cylinder is not in an upright position. However, it is recommended to keep the torch upright as much as possible to ensure optimal performance.
To operate the torch, the ignition knob (2) must first be turned to the "LOCKED" position during assembly. For models with a flame adjustment knob (TS7000 and TS8000), the regulator valve should be turned off by rotating the knob clockwise until it stops. The gas cylinder is then threaded into the regulator/torch body and hand-tightened. It is crucial to ensure all connections are secure and to check for leaks using soapy water in a well-ventilated, spark-free area, never with a flame.
When ready to light, the ignition button (2) is turned to the "UNLOCK" position. For TS7000 and TS8000 models, the flame adjustment knob (1) is opened fully counter-clockwise before lighting to prevent damage to the ignition system. The torch should be pointed in a safe direction, away from people and flammable materials. The ignition button (2) is then pulled towards the user to ignite the flame. If necessary, this step can be repeated. Once lit, the flame size can be adjusted using the flame regulating knob (1) on applicable models. Releasing the ignition button (2) automatically extinguishes the flame.
For continuous operation, the flame lock feature can be engaged by pressing the flame lock button (3) while the ignition button (2) is depressed. To release the flame lock, the ignition button (2) is pulled until the flame lock button (3) disengages. After use, the ignition button (2) should be returned to the "LOCKED" position, and the regulator valve (if present) should be fully closed by turning the flame adjustment knob (1) clockwise until it stops. The cylinder should always be disconnected from the torch when not in use. Before storing, with the torch disconnected from the cylinder, it is advisable to point the torch in a safe direction and pull the ignition button (2) to release any residual gas.
Safety is paramount during operation. Users must always wear safety glasses and protective gloves. Radiant energy from the torch can harm eyes, so glasses with appropriate lens shade numbers (as specified in 29 CFR 1926.102) are required, varying from shade 3-4 for brazing and light cutting to 5-8 for heavy cutting and medium/heavy welding. Work should only be conducted in well-ventilated areas to avoid inhaling fumes from fluxes, lead-based paint, cadmium plating, galvanized metal, and other heating operations. Coatings like cadmium plating and galvanized metal should be removed by filing or sanding in the area to be heated prior to applying heat.
The torch should never be used to strip lead paint. When working outdoors, caution is advised on sunny or windy days, as bright light can obscure the flame, and wind can carry heat or sparks to unintended areas or combustible materials. Heating a surface can transfer heat to adjoining combustible or pressurized surfaces, so it's essential to ensure no unintended parts are being heated. The tip of the torch becomes extremely hot during use, necessitating precautions against accidental burns. The torch should never be used on or near combustibles, motor vehicles, gasoline-fired products, or hidden fuel lines and tanks. It is critical to place the torch on a level surface when connected to the fuel cylinder to prevent tipping, and to ensure it is not pointed at objects that could ignite. Overheating surrounding materials should be avoided, and a heat shield should be used when necessary. The torch should never be left unattended when lit. Attempting to repair or heat gasoline tanks, chemical drums, aerosol cans, or compressed gas containers that held flammable liquids or gases is extremely dangerous, even if they appear empty, due to residual vapors. A fire extinguisher and a bucket of water should always be kept nearby. This torch consumes oxygen and must only be used in well-ventilated areas, never in a confined space.
Regular maintenance and checks are crucial for the safe and effective operation of the Bernzomatic Trigger-Start Torches. All joints and couplings should be periodically checked for loose connections. If bubbles appear when testing connections with soapy water (with the valve open but unlit), it indicates a gas leak, and the torch must be repaired or replaced. A flame should never be used to check for leaks. This test must be performed in a well-ventilated and spark-free area, away from open flames.
Before installing or removing cylinders and accessories, the torch must be cool. Using the torch with a low flame can potentially damage the burn tube and ignition system, so it's important to ensure proper flame settings during operation. In cold weather, the flame size may be smaller; pre-warming the cylinder to room temperature can help produce a larger flame.
For storage, the cylinder should always be disconnected from the torch when not in use. The ignition button should be in the "LOCKED" position, and the regulator valve (if applicable) fully closed. The torch and cylinder should be stored separately, out of reach of children, and in well-ventilated areas. Cylinders should not be exposed to temperatures exceeding 120°F. The torch should be treated as a fine tool, avoiding dropping, throwing, or other forms of abuse. A leaking, damaged, or malfunctioning torch should never be used. Users should never attempt to modify the torch's construction or use unapproved accessories or fuels. Keeping the torch out of reach of children and individuals who have not read the instructions is essential. The torch should never be pointed towards the face, other persons, or flammable objects, and should never be used as a cigarette lighter.
