How much firepower do I need in a torch?

[Luann Udell]

Hey, I've been using R&T's micro torch http://shop.rings-things.com/cart/pc/viewPrd.asp?idcategory=2029&idproduct=17820 for awhile now.  I LOVE it!  I make my handmade headpins by "balling up" the end of sterling silver wire pieces, and use these for large pendants, cold joins, etc.

I have trouble using this "ball" technique on heavier gauges of sterling wire.  I THINK it's the 18 gauge or perhaps 16 gauge.  (I can tell my next tool will be a wire gauge measure!!)  Just can't heat the end hot enough to melt and ball up the end.  Do I need a bigger torch??

Metalman, do YOU know?  You are our last hope, Skywalker....

Oh shoot!  He was here just minutes before I read this.  And my other best bet is in Tucson right now.  I'll see if I can get you an answer over the weekend.

Yep, Dee says a bigger torch is the deal. You just can't produce enough heat. A regular propane torch like for sweating copper plumbing does not get hot enough, either, you need Oxy & Propane for the heat.  You could make the big jump to Oxy and propane (or oxy & Acetylene) and a "mini torch."

We just saw a more powerful small torch at show. It's very portable and probably fire marshall legal at most shows. I'll get the name & post it later tonight. It used bigger cans of gas but not like welding size tanks.

Dang.  Okay, maybe it IS time!  Please keep me posted, Russ.

Found my literature from AGTA show on the "Miniflam" microtorch.  http://miniflam.com/

I some ways it's like a full bodied version of the creme brule torch you have when you connect it to the mini containers. When connectd to regular Oxy and Propane tanks it woks like the Smith  "Little Torch" Gentec "Small Torch" and other jewelers size torches. These all have more precise tips and flames than the standard Hoke style torch.

Spent some time at Rio's Catalog in Motion today. Dee watched demos on Argentium fusing. She used a very small torch connected to a small propane tank. Will find details for you on that.

Sorry its been a while - I like the acetylene air torch Smith makes called 'Silver Smith'
I am guessing $135 to 150 plus your tank.  The little 'M' tanks are a pain so I recommend a larger one.
I  bought one of those 'Little Torch' torches about a year ago [man I like that torch]
but Luann - you need to think about what you are doing/making and make a plan for this purchase.
The tanks/regulators /hoses/carts can add up - I try to not duplicate expenses.
