Fuel / Safety information

BernzOmatic manufactures fuel cylinders and tanks for propane, MAP-Pro™, and oxygen gases. Choosing the right fuel -- and using it safely -- depends on the task you're performing and what type of hand torch you're using. The following tips can help you make the right fuel choices. You can also contact BernzOmatic for help selecting the right fuel and products for your needs.

Fuel Information

How Hot?
200-400 degrees F Softening putty or paint
350-840 degrees F Soldering: joining metals with a low-temp metal filler for plumbing and electrical projects
400-800 degrees F Thaw frozen locks and rusted nuts / bolts
840-1,500 degrees F Brazing: soldering with a hard filler
1,250-2,800 degrees F Welding metals together
2,400-3,000 degrees F Cutting Steel

Hot Spots

A single torch flame has many different temperatures. For any gas, the hottest part of the flame is at the tip of the inner flame, where the pale outer flame meets the darker inner flame.

Fuel Uses
Oxy / MAP-Pro™: Flame temperature in air is 5,200 degrees F. Ideal for: Cutting and welding iron and steel, when you don't need a sharp flame like an oxy-acetylene torch. Oxygen and MAP-Pro™ Premium Torch Fuel cylinders and a specialty oxy-fuel torch are needed.

MAP-Pro™: Flame temperature in air is 3,730 degrees F. Ideal for soldering larger size copper pipes, brazing, heat-treating. Higher flame temperature and better combustion intensity allows tasks to be completed more quickly. Choose a torch specially designed for MAP-Pro™ fuel.

Propane: Flame temperature in air is 3,600 degrees F. Ideal for soldering copper pipes, heating frozen pipes and rusted nuts, softening paint and other low-heat DIY projects. A self-igniting torch is safer and more reliable than a spark. Pick a wide flame for most applications which don't need pinpoint-type heat.

General Safety Precautions

  • Read and follow important safety warnings included with BernzOmatic fuel cylinders and hand torches. Always use protective gloves and safety goggles while using hand torches.
  • Check cylinder and appliance seals before using BernzOmatic products. Never use cylinders with damaged or missing seals. Discard cylinders if dirt or rust particles are present in valve areas.
  • Make sure your appliance is turned off before attaching a fuel cylinder. Attach outdoors away from pilot lights, flames, sparks, or other ignition sources that can ignite leaking gas. Be sure to hold cylinder upright while attaching hoses or appliances. Hand tighten only -- never use tools to tighten -- as over-tightening can damage seals.
  • To check for leaks once appliances are attached, put soapy water on connections and look for bubbles. Also listen for the hiss of escaping gas; feel for extreme cold; and smell for rotten egg odors. Do not use cylinders if you detect fuel is leaking from valves or connections.
  • During use, hold hand torches upright to prevent flare-ups or flashes. If appliance sputters or flares up, turn cylinder upright and turn unit off. Vent area to remove unburned gas. Slowly turn on. After hearing a slight hiss, re-light the torch.
  • Never use hand torches near pilot lights, flames, sparks, or other ignition sources. They can ignite leaking gas.
  • Allow hand torches to cool after use. Detach fuel cylinders when not in use and replace caps to keep valves clean.
  • Never drop, throw or puncture fuel cylinders. Store fuel cylinders away from living spaces and out of reach of children. Never leave in direct sunlight. Never store at temperatures above 120 degrees F (49 degrees C).
