Silver Solder Torch Selection

[ChazzC]

Got an answer from Bernzomatic on the output of the 8250-series torches:

Actually, they replaced the original answer which was this:

"Thank you for your question! If you’re currently using propane, which has a maximum burn temperature of 3,600°F, you might consider switching to MAP-Pro fuel. MAP-Pro burns slightly hotter, reaching a peak temperature of 3,730°F, which offers a modest increase in heat."​

​

When I checked the "No" button under "Helpful?" yesterday morning, they replaced the response with the actual answer to the question just now.

Interesting that you should post this, because I contacted Bernzomatic as well last night and was emailed the specs as shown below. So, I cancelled the order for the 8250 just got back from a local store and bought the 8000 with a hose kit. Should be a little better. Going to try it out later after playing some pick-up hockey.

What is the BTU rating for the BZ8250 HT torch? Propane 10229 – MAP Pro 9250

What is the BTU rating for the TS8000 T torch? Propane 14282 – MAP Pro 12915

That's interesting since they both have the spiral burner (I forgot to go back to my earlier post on the 8000); I would have though the only difference was the permanently attached hose with remote regulator.

Although the 8250 has less heat output, with the remote regulator you have the freedom to use the touch head at odd angles, which is an important consideration.

I hope that the hose kit I purchased takes care of that. Please let me know what you think.

Hose kit is just that, a hose with a shut off valve at the cylinder end; the regulator is still in the base of the torch head. As long as you don't tip the bottle you should be ok?

Heating is complicated and BTU's are as useful to judging a torches performance as gas tank volumes on cars.

Max flame tempurature, flame front speed etc... all play huge rolls in getting the heat where and into what you want to heat.
