Product Description


The BernzoMatic trigger-started cast aluminum torch head light is a self-igniting high-temperature torch head designed for easy operation. Simply pull the trigger for ignition, and release it to turn off. This head produces a swirl flame and burns propane or mapp gas. Pressure regulation allows the flame to burn in any direction and ensures consistent performance. Even while the flame burns, the replaceable brass tip stays cool. The stainless steel burn tube, cast aluminum body, and brass burn tip are constructed for durability. The BernzoMatic torch head weighs 1.3 pounds and is backed with a 1-year limited warranty.

I thought I'd invested a little extra money for convenience and durability. Wrong.
While the TS4000 I purchased from Amazon worked flawlessly for 8-10 hours of use, it won't start at all after having sat idle for 8 months. When I start it 'manually' via an aim-n-flame, it has a broad fan-shaped flame that doesn't heat property.

I guess the instruction manual should have said to test the TS4000 before each job, as it is not a dependable tool. Now I'm stuck with no water, an upset pregnant wife, and a run to Lowes to pick up another 'disposable' torch.

Shame on Bernzomatic.

UPDATE: The broad fan-like flame was caused by some "micro-webs" in the neck of the torch. While they didn't look like they could possibly block the airflow, I guess they were sufficient to disrupt the swirling mixture of air/propane. I blew them out with some compressed air and the TS40000 is acting like new. I now store the "torch" in a large zip-top freezer bag to keep out the beasties.

Shame on me for blaming Bernzomatic for my spider.

Like other reviewers, I think the Bernz-o-Matic TS-4000 Trigger Start Torch Head is a good piece of plumbing equipment. My only addition to their comments is that I have been through three of these in about 5 years. They get to the point where the piezoelectric sparker just stops working. I am an average homeowner who uses the torch infrequently for plumbing, and almost weekly for starting the charcoal grill or wood stove. When the torch no longer sparks, it is just as good as any other, much cheaper, torch head.

I got this after using my dad's while visiting my parents at their cabin in the mountains. There are a zillion uses for this thing -- lighting the grill, starting fires (stubborn green brush / wet wood don't stand a chance before this thing!), torching ant / hornet nests, lighting fireworks, soldering, joining pipes (if you're a plumber), etc.

After using my dad's Bernzomatic up there for a week, I knew I had to get one as soon as I got home... and I did.

This thing is sweet. You can use it with Propane or MAPP gas; MAPP is about 2.5x the price (around seven-fifty at my local HW store, whereas the Propane was something like three bucks) but burns much hotter. For my purposes (lighting fires, starting the grill, and roasting ant beds... basically just playing around), normal Propane is more than sufficient. You can use the tall blue propane cylinders from your HW store, or the squat / fat dark green ones you'd normally use for your camp stove / lantern... it's a standard connection.

The Bernzomatic unit itself is built very solidly. The whole thing is made from metal, except the plastic clicker, which is still heavy-duty and feels nice and durable. It has a pleasant heft and a solid 'quality' feel, and is surprisingly ergonomic in the hand while connected to either the tall skinny containers or the short fat ones.

The unit will start on the first click almost every time -- sometimes it takes two clicks, and I believe this is because if you click it too fast, gas doesn't have time to actually reach the piezoelectric starter before it sparks. But this just means you click it twice (or wait a quarter of a second between pressing the button halfway and clicking it fully). The unit is, thus far, utterly reliable and very heavy duty.

Before buying this on Amazon, I read many of the reviews for the product, including many from seemingly qualified plumbers discussing how to sweat copper and so forth. Let me just say that I have absolutely no professional need for a blowtorch and will not presume to discuss this product's utility in that context. To my layman's eye, it seems very sturdy and has worked well.

What I will say is that I have tried a few blowtorches in various settings and this one has functioned flawlessly for several months - including resolving a problem on another blowtorch: the lack of pressure regulation which causes the blowtorch to go out when aimed downward or inverted. Without this feature it is next to impossible to sear steak, glaze creme brulee, or do other things made more fun with a blowtorch that require a flame directed downward. This torch is able to used in any position, including upside down. Just today I did an experiment with my kids to verify that older pennies have a much higher copper content and thus get hot but don't melt, while newer pennies are mostly zinc and melt in seconds.

Several reviewers noted that the internal ignition mechanism stopped working after a while. That hasn't happened with mine (yet) and it always lights on the first or second try. You can also light it externally with a standard flint spark igniter - the kind your father or grandfather would have used (I also use these for my gas stove as I'm too lazy to fix the sparker and they are more reliable, cheaper, and last longer than the long-necked butane lighters). If this ever happens to me, it won't affect my ability to use it, but for professional use you can see how the ability to quickly activate and deactivate the torch on selected spots would be key.
