How to Fix Your Butane Torch

flame from butane torch

Anyone who uses a butane torch regularly will probably realize that short of a total malfunction with any of its working parts, a butane torch generally only requires filling with a new butane to ensure its ongoing operation. These portable torches are surprisingly durable and if you are capable of filling the torch, you will likely experience no other issues in terms of keeping it maintained.

Always Use Manufacturer Recommended Butane

If your butane torch or lighter stops working, use the correct grade and brand of butane. Using the incorrect type or low quality can often be the reason for your torch not operating correctly, so it’s always a good idea to check for any recommendations from the manufacturer about the specific type of butane they recommend for your particular torch or lighter. One of the symptoms of lower-grade fuel is flickering or sputtering of the flame; this symptom can also be caused by air in the fuel cell, which can be resolved by removing the air.

Ignition Systems

Butane torches these days are generally equipped with instant electronic ignition systems and these have a reputation for being reliable technology. There will always be exceptions though and if your torch won’t ignite, you have a couple of options with regard to fixing it.

The first is to try and regulate the flow of gas because it may be too low for optimal ignition. You can turn the gas output all the way up then turn it back after the gas is ignited. If this doesn’t help, you could consider the warranty options on the torch and seek a replacement because it may be that the ignition is faulty.

The Nozzle

Under normal circumstances, the nozzle shouldn’t become clogged because butane is a ‘clean’ fuel and does not produce soot to clog the nozzle. What can occasionally happen, though, is if you are using the torch for soldering, a tiny piece of solder may become lodged and stuck in the nozzle. To fix your torch, ensure your torch is off and completely cool. Attempt to remove the offending particle(s) of solder. One way to clean out the nozzle is to shoot compressed air into the nozzle area where the gas exits the torch. This may dislodge any foreign matter that is causing the suboptimal performance. Carefully use a needle or a specialized jet-cleaning tool for more thorough internal cleaning to dislodge any blockage within the jets. This should be done with care to avoid damaging the delicate components. After dislodging any debris, direct a stream of compressed air through the jet to clear out any remaining particles. It’s important to follow the manufacturer’s instructions and recommendations throughout this process to prevent damage to your butane torch.


Fixing your torch is not something which should concern you unduly because the most likely scenario for it not working will be because you need to fill the torch with quality butane gas. Filling a butane torch can generally be accomplished quickly and using the best quality butane will always help your torch to function at its optimal level. General care in looking after portable tools such as keeping them clean and in good order will also help to ensure the longevity of your torch.

  1. The refill port on my Blazer leaks. I’ve disassembled the valve port and discovered that the tiny “O” ring has deteriorated and needs to be replaced. Where can I buy a new “O” ring?
