Propane / Oxy

Has anyone any thoughts on using the turbotorch kits for silver soldering once the piece is heated up.Are the gas bottles big enough and is it cost effective

Thanks,
Bob

If by turbotorch you mean the mini twin bottle kit then I have used that type when working on refrigeration pipework repairs.

They do a good job but the burn time is dependent on the size of the oxygen bottle in use. A small bottle would give me around 15 minutes, now you need to work out how expensive to run these units are.

A good MAPP gas torch can do most things and with a twin burner head you can cook most things.

I saw a demo at the Midlands show by Helen from Western Steam and Keith from CupAlloys making a small boiler. The boiler was heated first using a propane torch before Helen finished things off using a Oxy turbo kit.

I think there was a video on CupAlloys site

To prevent any confusion.

The oxy-turbo kit runs off disposal canisters of oxygen and mapp gas. The oxygen lasts about 20 minutes. The gas about 40 mins. Replacement canisters are available via CuP.

The demo at the Midlands featured preheating with a conventional propane torch before using an oxy-propane flame to reach brazing temperature and create the necesary heat pattern. This kit runs off larger refillable cylinders. One of the major benefits of this kit is that you own the cylinders which you simply pay for their refilling. There is no cylinder rental fee, no maintenance charges or contract. They are your cylinders. Refills are readily available from gas suppliers but not CuP.

Both are good products to meet different needs.
