Which torch do you recommend for a DIYer?

The TS3500 Multi-Use 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.

Which torch do you recommend for a professional contractor?

The TS8000 Max Heat Torch works well for many heavy duty tasks. Its ultra-swirl flame provides maximum heat for large diameter soldering or brazing. Its durable cast aluminum body is built to last.

Which fuel should I use for my project?

Butane: Well-suited for soldering electronic circuits, heat shrinking and jewelry design and repair.

Propane: Ideal for small soldering jobs, softening putty or paint and loosening rusted bolts.

MAP-Pro™: Designed for larger, hotter jobs such as soldering large diameter copper pipe, brazing or heat-treating.

Oxy/MAP-Pro: These torches are hot enough to weld and cut thin metal.

Why is my torch so hard to light?

Most torches light better when the valve is just cracked open and there is light gas flow. Learn more.

Why does my torch go out when tipped upside down?

Some of our torches (WT2301, WT2301C, WPK2301 and UL2317) 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 theses 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 TS3500 Multi-Use Torch or a cast body torch, such as the TS4000, BZ4500HS, or TS8000.

How do I inspect my torch and cylinder for potential gas leaks?

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, test all connections with soapy water. If bubbles appear, gas is leaking, and the torch must be repaired or replaced. Never use a flame to check for leaks.

Why do I only get a small flame out of my torch in cold weather?

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. We recommend a pressure-regulated torch, such as the TS3500 Multi-Use Torch.

Why did my torch head break at the air holes?

All of our torches are designed to absorb impact and reduce damage to the cylinder if dropped or abused.

Can I replace the igniter on my torch? Do you sell replacement igniters?

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.

What is the warranty on my torch?

Please see our product page for warranty information about your specific torch.

Where can I buy an item that I can't find in a store?

Use the search feature to find the product you’re interested in and click on the Buy Now button for a list of retailers that carry the product.

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.

What happened to the QuickFire drill-style torch with the small, 1/4 turn cylinder? I can't find replacement fuel for my QuickFire torch.

The QuickFire torch and the QuickFire fuel cylinder were discontinued in October 2012 and are no longer being manufactured. We recommend you replace the QuickFire with the TS8000 Max Heat Torch, which has similar flame characteristics and uses MAP-Pro fuel.

How do I dispose of my 14.1, 16 or 16.4 oz. fuel cylinder?

Bernzomatic cylinders are both disposable and recyclable, but each municipality has its own regulations for recycling. For information on how to dispose of 14.1, 16 or 16.4 oz. non-refillable fuel cylinders, visit our CylinderSafe 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.

Can Bernzomatic products be transported on an aircraft?

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

Where can I find instructions for my torch?

All instructions may be downloaded from our Product Support page.

How do I contact customer service?

You can contact us by email or via our website.

Why did the oxygen tank in my brazing torch kit run out of fuel so soon?

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

Why is my 20 lb. propane cylinder empty? I just bought it.

This tank is marketed and sold as an empty tank. It’s designed for those who prefer to have a cylinder that can be refilled and know the history and age of their tank.

Why won’t the ignition button on my 2200 Detail Torch work?

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.

Why did my hobby and household torch stop working after only a few uses?

Featuring a 3-in-1 tip, our 2200 Detail Torch and ST500 Cordless Soldering Iron are great for several different uses. However, if used as a gas torch without removing the soldering tip, damage can occur. Before starting a project, always make sure to refer to the instructions and specific assembly steps for your operation. For troubleshooting help, please contact our customer care team.

How can I improve the flexibility of hose that came with my torch?

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.

Is torched cooking safe? Does it leave a taste of fuel?

Yes – torched cooking actually originated with American chef, Julia Child, in the 1950s with a Bernzomatic torch, so it’s been tried and tested for years. 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. In addition, you have complete control over the distance between flame and dish.

Can I use my Searzall attachment with my Bernz torch?

Searzall is not manufactured by Bernzomatic and is not recommended for use. It pushes heat back down the burn tube and will melt your torch from the inside out, and also void the lifetime warranty. If you need heat to cover a wider surface area, we recommend our BZ4500 Heat Shrink Torch, since it’s made for large surface area and carries a lifetime warranty.
