Can you braze with a gas torch?

The heat produced by a butane torch is much lower than other welding torches and can not heat metals to a melting point. However, your butane torch may solder and braze surfaces common in plumbing and jewelry making by using a filler metal to bond the base metals or melt the finer components of gold and silver jewelry.

What gas do you use for brazing?

While acetylene gas is always required as the fuel for gas welding, braze welding can be performed with the other fuel gases such as propane, natural gas, propylene, etc., as well as with acetylene.

What kind of torch do I need for brazing?

For brazing small components and thin sections, you would want to use torches that provide the lowest heat and flame temperature. These torches used for these applications are the air-natural gas and air-acetylene.

How do you identify the fuel gas fittings on the torch?

The black hoses on the right are “A” fittings. These are the US standard fittings for oxy-fuel connections. Fuel is left hand thread, and the nuts have hash marks across the corners to identify them.

Is a butane torch hot enough for brazing?

There is no way you would be able to braze with a butane pencil torch. It won’t get hot enough, and it won’t hold enough fuel. You would have much better results with a setup that uses MAPP gas, and a micro torch.

Will a butane torch melt solder?

A butane torch creates a flame that can reach a maximum temperature of about 2,500 degrees Fahrenheit. These high temperatures—coupled with butane’s long flames, which can reach up to 6 inches long—make these torches capable of melting and soldering metals like copper and silver.

What torch Do plumbers use?

Propane torches are the most common type and are used by professionals and DIY homeowners alike. These torches are inexpensive and easy to use Professional plumbers often upgrade the torch assembly to a higher quality torch head with interchangeable tips, and a regulator to control the gas pressure.

What does CGA stand for in gas?

The Compressed Gas Association (CGA) has selected and standardized the valve outlet to be used on each gas cylinder.
