Some of our torches (MT525C, MT245C, and MT200C) are designed for plumbing or soldering – uses that work best with the torch head upright. For this reason, they do not have a pressure regulator to control the flow of fuel through the torch. When these torches are inverted, the liquid propane works its way through the torch and extinguishes the flame.

For work that requires inversion, we recommend a pressure-regulated torch, such as the MT535C, MT551C, MT555, MT560C, MT565C, or MT579C.

The MT535 torch is a versatile torch well suited to a variety of tasks, including light soldering, lighting grills, loosening rusted bolts and softening putty or paint. It features an automatic ignition that instantly ignites the flame without the hassle of a spark lighter and works inverted.

The MT579 torch works well for many heavy duty tasks. Its ultra-swirl flame provides maximum heat for large diameter soldering or brazing.

Butane: Lowest heat transfer and well-suited for soldering electronic circuits, heat shrinking and small jewelry design and repair.

Propane: Ideal for small soldering jobs, softening putty or paint, loosening rusted bolts, creating a patina on wood or metal. Compatible with many hand-held torches.

MAP-Pro™: With high heat transfer, MAP-Pro is ideal for jobs requiring high heat such as soldering large diameter copper pipe, brazing or heat-treating or for larger jobs when you want to heat the materials faster. Use only with torches designed for MAP-Pro.

Oxy/MAP-Pro: These fuels in combination provide the highest heat transfer torches are hot enough for light welding and cutting thin metal. Must be used with a torch specifically designed to combine the fuels like the MT585OX.

Most torches light better when the valve is just cracked open and there is light gas flow, then fully open the valve when using the torch. This is a multi-dimensional question, with a few things to troubleshoot. When looking at a torch igniter that is not working, there are 3 components to consider: Is there a spark? Is there a flow of fuel? What is the cleanliness of the torch tip and tube?

Troubleshooting the Igniter

For instant on/off or automatic ignition torches:

  1. Open the valve of your fuel cylinder
  2. Unscrew the torch tip
  3. Press igniter to see if there is a spark

If Yes: Replace tip and skip to Fuel

If No: Try the remaining troubleshooting steps, and if still no spark, contact Customer Care or email

For manual ignition torches:

  1. Open the valve of your fuel cylinder so there is a light flow of gas
  2. Use a lighter or spark lighter at the tip of the torch to ignite the flow of gas

Troubleshooting the Fuel Cylinder

  1. Check the black safety cap: Has it been removed prior to attaching your torch? *This should be removed prior to use
  2. Does your cylinder have fuel in it?
  3. Is your torch properly attached? *The torch should be lightly threaded on, and not over tightened or cross-threaded
  4. Is the valve open?
  5. Are you using the correct fuel for your torch?

If all of these are true, proceed to Cleanliness.

Troubleshooting Cleanliness

  1. Does the tip and tube appear to be free of debris?

If No: If there is debris in the tip and/or tube, this can easily be cleaned with either:

  1. An Air Compressor: to simply blow the debris free of the tip and tube
  2. Or with a soft pipe cleaner threaded through the tip and tube to gently clear debris. *Using any other item such as a brush etc. will likely damage the ignition wires or the swirl fan inside some types of torches.

If Yes: Contact Customer Care or email as this may be a larger issue such as a pressure fault.

Conduct a leak test in a well-ventilated and spark-free area where there are no open flames. Attach torch to fuel cylinder. With the valve open, without lighting, rub soapy water on all connections. If bubbles appear, gas is leaking, and the torch must be repaired or replaced. Never use a flame to check for leaks.

On a torch that is not pressure-regulated, the size of the flame varies with the pressure in the gas cylinder. When it is very cold, there is a reduced amount of gas pressure in the cylinder. For cold-weather projects, we recommend a pressure-regulated torch, such as the MT535C.

We do not recommend that users replace igniters. However, corrosion on the ignition wire or a blockage in the burn tube may prevent a torch from lighting and can be easily repaired. For instructions, contact our customer care team.

All Mag-Torch hand torches carry a one-year limited warranty.

Many retailers make our products available for order and shipping through their online stores. While federal regulations prevent the shipping of hazardous materials such as flammable fuel through the mail or via air cargo, it may be possible for the product to be routed to a store near you for pick-up in person.

If you’re unable to find where to buy a specific model through a web search of retailers near you, contact our customer service team and we can check availability.

Fuel cylinders are both disposable and recyclable, but each municipality has its own regulations for recycling. For information on how to dispose of non-refillable fuel cylinders, visit our CylinderSafe resource page. If you have any additional questions, please contact our customer care team.

Safety Note: Empty cylinders may have some pressure still from lingering fuel vapors and should not be punctured.

Most Mag Torch products are not permitted to be carried on to aircraft. Visit the FAA Packsafe page for details.

The oxygen tanks are designed for smaller projects and burn at a much higher rate than torch fuel. Oxygen tanks generally run at a 4:1 ratio when compared to MAP-Pro. Depending on your project, additional oxygen cylinders may be required.

Be sure that the safety lock button is disengaged before trying to ignite. The safety lock button is just under the ignition button; slide the lever down and the trigger will be able to move freely. If you need additional troubleshooting help, please contact our customer care team.

Stiffness is usually caused by coiling during packaging. Before first use, we recommend laying the unit flat for a few minutes to allow the material to relax. The flexibility of the hose will improve with each use.

Yes – torched cooking is safe – it’s been tried and tested for years. In fact, in the 1950s, Julia Child started torched cooking with a Bernzomatic torch. It’s also a great approach to cooking, as you have complete control over the distance between the flame and the dish. We recommend using clean-burning propane fuel for cooking. It’s the same type of fuel used with gas grills use and is approved food-grade fuel by the FDA.
