Features:

  • Manual start (light with a Bernzomatic Spark Lighter, sold separately)
  • Broad flame for small diameter soldering, thawing, melting and heat application
  • Use only with propane fuel, such as the Bernzomatic 14.1 oz. Propane Hand Torch Cylinder

Durability

Bought this jumbo flame torch head to get away from the pencil flame head that I was using. The pencil flame took seemed like forever to head up 3/4 inch copper pipe but the jumbo flame does the job in no time. This new model has a flat area at the base where you can use a wrench to snug up the head without applying pressure to the side of the valve to snug it up. Be careful and don't get carried away with the wrench, just a little pressure will do it. All in all, I wish I had bought this jumbo head years ago. A great product. Just remember for plumbing to set the flame where the inner cone shaped blue flame is about 3/4 inch high.

Very nice step up from the Bernzo pencil torch

My old BernzoMatic pencil beam torch got misplaced, and I needed to heat up a large area (on an axle tube) anyway, so I spent the extra $5 for this "Jumbo" model. Well worth the difference in price I light my pellet stove with propane as well and this bigger torch cut lighting time down in half, or less. Though it does seem like it will be a "bottle drainer" uses more propane than the old pencil torch. In response to other reviews, I was able to regulate the propane flow down low without noticing any more heat build up but maybe that will change (?) Also, shutting mine off doesn't take any more effort that any other torch I've had, but (because of the other reviews) I was making the extra effort to stop turning as soon as the flame shut off and not over tighten it/damage the valves internals. I remove the torch from the bottle when not using it, and I try not to run it inverted (running any torch inverted can fill the torch with liquid propane and make it not shut off immediately when the valve is closed) Either way, great torch so far, recommended!

Just what I was looking for

New propane torch kits come with valve/head units that have a stem that is so small it will hardly light or stay lit. This is just like what we used to get years ago with a propane torch kit. Threw all the new crap away after getting this. I am one happy camper.

0 problems in 7 years

Even though I got it so hot the knob melted a bit.

Great flame for any propane task

I like the heat from the burner. The configuration worked really well. What I didn't like is its hard to turn off. It keeps burning even after being turned off -- maybe 3 seconds. The one i threw away was the same company and it would burn for 10 seconds. I hope the company provides me one that shuts off well. I still gave it 5 stars. Pricing was great.

Strong torch, perfect for soldering pipe.

I had a regular torch, and it didn't generate enough heat to solder even 1/2 inch pipe with 95/5 solder. I bought this and it's quick and easy. Lights easily, stays lit, makes a fairly wide but concentrated and focused flame.

Perfect for searing sous vide.

Really throws out the flames. Used for searing sous vide meats and works wonders. Has a wide flame that sears well without scorching. Very sturdy brass construction.

Top quality, tight flame

I bought the large tip torch because I needed a loose, big, bushy flame. Instead I got a precision-machined, carefully engineered torch with a perfect focus flame and high efficiency fuel use. I had to return it and get a lower-grade torch for my specific needs. It's a pity, because this is rock solid for the price, and I recommend it highly.

A high-performance torch, while it lasts.

I use this torch for defrosting my upright freezer. It does the job in half the time that it took my wife's 1500 watt hairdryer to do the job. However, it apparently not for continuous use. I defrosted the freezer about four times and the valve on the torch died. It won't open anymore, so the torch is now useless.

BernzoMatic JT680 019110 Jumbo Flame Torch Head

I like this torch. I sometimes make stuff out of silver sheet and silver wire and gallery wire. Small jewelery like things. Silver soldering is slightly more like brazing than soldering up a fiddle's stompbox. When I set out a few small pieces of silver to get carefully stuck together, a large flame blows them all across the soldering board as is the case with most pencil torches. Not good. I don't do this often enough to warrant profesional torch/tips, so I get to use pencil type torch heads. They usually have way too much velocity for my use but the JT680 lets me adjust it, that is, until some ironman wanna be, over-tightens the valve when turning it off and damages the soft brass needle valve making a "ring dent" around it. That's usually the end of adjustability and usefulness--to me. I added that for those who have never purchased and used their own brass torch as a word of caution, if finer adjustability is desired feature. Don't tighten the knob down more than it takes to stop the flame. If leaks are a concern, remove the torch head when not in use. This torch tip has a 5/8" inside diameter and has manufactured on it cooling fins so that it can be adjusted down to a small flame without undue/unsafe heat accumulation. I presume. The cooling fins, 4 machined grooves 1/8" wide/deep do not do a very good job of keeping the torch cool, but it get's less hot than the personally modified BernzoMatic 370A Torch head that would get as warm as any Japanese nuclear event. A no-no I found out. I usually use the torch at about ½" of bright blue flame and about 2" flame in all. I LOVE the 5/8" width of the flame so I don't need to "wave" the flame as much to heat larger pieces up evenly. WOT gives you a 9" long flame (When using a full bottle of cheap/readily available Coleman Model # 5103B738T propane) and a bright-blue flame that is 1½" long x 3/4" diameter approx. 3/16" past the end of the tip, giving a usable length of about 7 inches. The price is cheap so yes the knob IS plastic. I have not melted it running the torch on a small flame for 2+ hours continous, as I did on the aforementioned personally customized BernzoMatic Model 370A, so the cooling fins seem to keep the JT680 as cool as an unmodified 370A. One more word of caution. Look at the contact surface of your propane bottles and watch out for nicks and dented ones. They leak and can tear up the pretty cork gasket, which is so hard to find out here in the sticks, making the purchase of another torch, a nice feasability at the price.
