Which torch would you recommend to a DIY'er?

The TS4000 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 a trigger on/off switch that instantly ignites and extinguishes the flame without the hassle of a spark lighter, and is compatible with both propane and MAP-Pro fuel.

Which torch would you recommend to a professional contractor?

The TS8000 is one of our hottest, fastest torches available. Its high-intensity, ultra swirl flame provides maximum heat for fast soldering or brazing. Its durable cast aluminum body is built to last.

Which fuel should I use for my project?

  • Butane: Butane torches are well suited for soldering electronic circuits, heat shrinking and jewelry design and repair.
  • Propane: Propane torches are ideal for small soldering jobs, softening putty or paint and loosening rusted bolts.
  • MAP-Pro: MAP-Pro torches are designed for larger, hotter jobs such as soldering larger copper pipes, brazing and heat-treating.
  • Oxy / MAP-Pro: Oxy / MAP-Pro torches are hot enough to cut and weld iron and steel.

Why is my torch hard to light?

Most torches light better when the valve is just cracked open, and there is a small gas flow.

Why does my torch go out when tipped upside down?

When a non-regulated torch is tipped upside down, the liquid propane in the torch works its way through the torch and extinguishes the flame. We recommend a pressure regulated torch, such as the TS3000.

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 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 TS3000 Trigger-Start Torch Head.

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?

No. 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.

My torch is defective. Where can I get it repaired?

Please contact our customer service department or call 1-800-359-9678.

What is the warranty on the torch?

Bernzomatic products are guaranteed for one year against manufacturing defects and workmanship.

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

Use the search feature on our website to find the product you’re interested in, then click on the Where to Buy tab to see a list of retailers who carry that 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, 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. Please contact your local waste management company to learn about the proper recycling or disposal process in your area.
