 DANGER
ENGLISH | ANGLAIS | INGLÉS | INGLÊS
This torch is used with a flammable product. Failure to comply with these Warnings and
Instructions may result in an explosion or fire that may cause property damage, serious
personal injury or death.
Read and comply with the instructions and warnings in this manual and familiarize yourself
with the torch before lighting and using. Review instructions and warnings periodically to
maintain awareness. Do not try to operate before reading instructions.
Torches are to be used only with hand held gas cylinders specifically designated for
use with torches.
 WARNING
• Keep torch out of reach of children and anyone who has not read instructions. Do not point torch towards face, other
persons or flammable objects. Never attempt to use torch as a cigarette lighter.
• Disconnect cylinder when not in use.
• Never attempt to modify the torch construction and never use unapproved accessories or fuels.
• Treat the torch as you would any fine tool or instrument. Do not drop, throw, or otherwise abuse.
• Do not use a leaking, damaged or malfunctioning torch.
• Always wear safety glasses, protective gloves and use proper tools to handle hot work.
• Radiant energy can harm your eyes. Wear glasses having an appropriate lens shade number (see 29 CFR 1926.102)
for the torch operation being done; brazing and light cutting (3 or 4), medium cutting and light welding (4 or 5), heavy
cutting and medium/heavy welding (5-8).
• Work only in well-ventilated areas. Avoid the fumes from fluxes, lead-based paint, and all metal heating operations. Be
careful to avoid fumes from cadmium plating and galvanized metal- remove these coatings in the area to be heated by
filing or sanding prior to heating.
• Never use torch to strip lead paint.
Materials used in the construction of this device may contain brass (which may contain lead), a chemical known to the
State of California to cause birth defects or other reproductive harm.
Combustion by-products produced when using this device contain chemicals known to the State of California to cause
cancer, birth defects, or other reproductive harm.

This document describes the Bernzomatic Trigger-Start Torches, models WT2301 and TS3500, which are designed for use with flammable gas cylinders.

Function Description:

The Bernzomatic Trigger-Start Torches are tools used for various heating applications, including brazing, light cutting, medium cutting, light welding, and medium/heavy welding. They are designed to ignite and maintain a flame using a hand-held gas cylinder. The "Trigger-Start" feature indicates an integrated ignition system, allowing for convenient lighting of the torch.

Important Technical Specifications:

The manual does not explicitly list detailed technical specifications such as BTU output, flame temperature, or specific gas types. However, it implies the following:

• Fuel Type: Designed for use with hand-held gas cylinders specifically designated for torches.
• Ignition System: Features a trigger-start ignition button (2) for easy lighting.
• Flame Adjustment: Equipped with an adjustment knob (1) to control the flame size.
• Burner Tube: Includes a burner tube (3) where the flame is produced.
• Construction Materials: Materials used in construction may contain brass (which may contain lead).

Usage Features:

• Trigger-Start Ignition: The primary feature is the trigger-start mechanism, which allows users to ignite the torch by pulling an ignition button. This eliminates the need for external lighters.
• Flame Control: An adjustment knob enables users to regulate the flame intensity, making the torch versatile for different tasks requiring varying heat levels.
• Portability: Designed for use with hand-held gas cylinders, making the torch portable and suitable for various work environments.
• Safety Precautions: The manual emphasizes numerous safety features and warnings, including:
  • Always reading and complying with instructions and warnings.
  • Using only designated hand-held gas cylinders.
  • Keeping the torch out of reach of children and untrained individuals.
  • Not pointing the torch towards faces, other persons, or flammable objects.
  • Disconnecting the cylinder when not in use.
  • Never modifying the torch or using unapproved accessories/fuels.
  • Treating the torch as a fine tool to prevent damage.
  • Not using a leaking, damaged, or malfunctioning torch.
  • Wearing safety glasses and protective gloves.
  • Working in well-ventilated areas to avoid fumes.
  • Avoiding heating lead-based paint, cadmium plating, or galvanized metal without proper precautions.
  • Being careful when using outdoors due to wind and bright light affecting flame visibility and heat direction.
  • Ensuring no unintended surfaces are heated due to heat conduction.
  • Being aware of the hot tip and taking precautions against burns.
  • Never using the torch near combustibles, motor vehicles, or gasoline-fired products.
  • Placing the torch on a level surface when connected to the cylinder to prevent tip-over.
  • Not overheating surrounding materials and using a heat shield when necessary.
  • Never leaving the torch unattended when lit.
  • Never attempting to repair or heat gasoline tanks, chemical drums, aerosol cans, or compressed gas containers that held flammable liquids/gases.
  • Always having a fire extinguisher and water bucket nearby.
  • Using in well-ventilated areas only, as the torch consumes oxygen.
  • Starting with the adjustment knob closed (clockwise until it stops) before attaching the cylinder.
  • Pointing the burner tube away from persons and flammable materials during assembly.
  • Opening the valve fully (counter-clockwise) when lighting to prevent ignition system damage.
  • Not operating the ignition button while the torch is operating.
  • Closing the regulator valve fully (clockwise) to stop the torch.
  • Ensuring the torch is cool before installing or removing cylinders/accessories.
  • Being aware that low flame use can damage the burn tube and ignition system.
  • Pre-warming the cylinder to room temperature in cold weather for a larger flame.
  • Tipping the gas cylinder more than 60 degrees from its upright position may cause flaring.

Maintenance Features:

• Leak Checks: Periodically check all joints and couplings for loose connections. A crucial maintenance step involves testing for gas leaks using soapy water (with the valve closed and without lighting the torch). If bubbles appear, the torch is leaking and must be repaired or replaced. The manual explicitly states, "NEVER USE A FLAME TO CHECK FOR LEAKS." This test should be conducted in a well-ventilated, spark-free area without open flames.
• Storage: Proper storage is emphasized to ensure safety and longevity:
  • Always remove the cylinder from the torch when not in use.
  • Ensure the valve control knob is fully closed before disconnecting.
  • Store the torch and cylinder separately and out of reach of children once cool.
  • Do not expose cylinders to temperatures exceeding 120°F (49°C).
  • Store cylinders in well-ventilated areas.
• General Care: The manual advises treating the torch as a "fine tool or instrument" and avoiding dropping, throwing, or otherwise abusing it to prevent damage. It also warns against using a leaking, damaged, or malfunctioning torch, implying that such devices should be repaired or replaced. The document does not provide instructions for user-level repairs beyond leak detection, suggesting that complex issues should be handled by professionals or lead to replacement.
