    How hot is the flame, could it melt 92.5% Silver?
    BySep 22, 2024
    1 Answer | 
    Answer This Question

    The flame temperature of the Bernzomatic TS4000 torch is approximately 3600°F with propane and 3730°F with MAPP gas. The melting point of 92.5% silver (sterling silver) is around 1640°F. Therefore, this torch can easily melt 92.5% silver.

      Hello, and thank you for your contact. We cannot guarantee the performance of your torch if you use it with a MAPP substitute. We can easily be reached at: Bernzomatic@WorthingtonIndustries.com if you have any additional questions. Thank you.

        Yes! these were made for true Mapp Gas back in the day. Ran hundreds of Mapp gas tanks thru these. True Mapp gas has been replaced with Map-Pro gas

              This type of torch head, is a flint-less ignition system, by using a small piece of quartz, with a special device to strike it, causing a shock/arch of electricity(Limitless).

                How do you narrow the flame?

                You don’t. It’s on or off.

                  This model does not have an adjustment knob. Instead the trigger itself is pressure sensitive. So careful modulation of your indexing on the switch will help to adjust the flame. Be cautious, this is not a toy, and the flame will ignite any combustible materials within 3 to 5 feet of the nozzle.

                    On this model you can’t narrow the flame nor the intensity. 

                    By|Jan 3, 2023

                      This model's flame can only be altered, by changing the tip itself, as there are no knob's for adjustment's. This has the spiraling tip, which narrow's the flame quite well.

                      By|Oct 17, 2023

                        You don’t with this torch. It’s either on or off, no adjustment at all if you want to narrow the flame you will have to buy a different torch. But if you don’t need to narrow the flame this torch is durable and very handy.

                        By|May 7, 2022

                          Hello, and thank you for your comment. The TS4000 torch does not feature a control knob, so the flame output on this torch will be a consistent and unchanging flame. If you have any additional questions, please feel free to email us directly at Bernzomatic@WorthingtonIndustries.com. Thank you.

                            Do not buy. Cast aluminum treads easily stripped.
                            I have purchased two of these torches. The thread to attach the MAPP bottle is cast aluminum and easily stripped, making the torch unusable. Look for a torch that has brass threads to attach the bottle. I found one and it works flawlessly.

                              Hello all just a fast note. I have had a ts4000 for 20 years, the base seal failed the other day. I called the mfr no issue, sent me a new one. Customer service and product quality of 10.
                              by
                                Consistent. Quality. Count on it. I've used this torch for many years. It fires up every time. No sputters. No hiccups. I know I can grab it and take care of whatever job I'm doing at the time. Whether it's heating metal to bend, or a punch to melt a hole in nylon webbing, the Bernzomatic torch is always ready.

                                This torch is well constructed with metal and seems like it will last me a while. I’ve been using mine for a few months, and it comes with me for everything from plumbing to camping. The torch is strong, burns clean and is easy and reliable to start. I like the extra safety feature to keep it from igniting while not in use!

                                  After years of using lighters and strikers, this torch is a game changer. Instant ignite and shutoff. Made soldering copper pipe a cinch. A job I used to dread, I’m actually looking forward to getting to use it again (as long as it isn’t in my own house). 🤣

                                      One Tough Torch!
                                      We used our TS4000 daily in a high school metal shop for 14 years. With multiple users every class, every day.... so conservatively 20 students X 8 courses X 85 class days X 14 years = 190000+ uses! We recently replaced the torch when the igniter would no longer work... unfortunately with a much lesser and more awkward to use TS3500 as the retailers in our area did not have a TS4000 to replace it with. If it can stand up to constant 'teenager' use, (and my use), its gotta be tough. Highly recommended product with no issues despite never disconnecting it from the tanks except for changeovers. Excellent value.
