Can you melt silver with an oxygen and propane torch?
only propane, it won’t generate as much heat as a propane and oxygen torch. If you are only soldering small bits of silver, your torch may be hot enough for you to melt silver solders. However, remembering that silver is a highly heat conducting metal, it will be sucking away your torch heat as you work. For this reason, you will
Can you burn gold with a torch?
Try using a propane torch to melt gold. As noted before, you must be extremely careful about safety concerns if you are going to use a torch. However, a torch will melt gold within a few minutes. The gold should be placed into a crucible. Then, put the crucible on a fireproof surface, and direct a torch toward the gold within the crucible.
Can brazing be done with propane?
Brazing with Propane. Here is the answer to whether you can braze with a propane / air torch. You can but you have to control the environment so that the heat loss to the atmosphere and parts is lower than the heat being put into the braze joint. It is a standard braze alloy that melts over a range of 1250 – 1305 F.
Can You braze with acetylene only?
You absolutely can braze with an acetylene TurboTorch. I've done it with mine fairly often.

How thick can a propane torch be?
A “propane torch” is marginal, but can definitely heat a limited thickness 3/16 to 1/4 thick steel bar hot enough to bend across the short dimension.
What kind of torch do you need to heat a bar?
You will need an oxy-acetylene torch with a rosebud tip to heat a bar thicker than 3/8 inch (10 mm) thick - or its equivalent in I-beam or C-channel rolled shapes. Angle iron (L shapes) are VERY DIFFICULT to bend accurately because the eccentric metal shape tends to twist and warp the bending force into “weird” geometries.
What type of torch do I use to solder copper water pipes?
I’ve used a propane-air torch for soldering copper water supply pipes in a house. It produces enough heat for soldering 1/2-inch and probably 3/4-inch copper pipe, despite the pipe carrying the heat away from the joint. However, a torch fueled by MAPP gas (possibly the same torch) is hotter, and allows working somewhat faster.
What is the melting point of a brazing rod?
Well, the melting point of your brazing rod is about 840 deg F, the melting point of Copper is about 1084 deg F and the temperature of your propane torch is 3600 deg F. So theoretically yes.
What kind of torches do plumbers use?
Professional plumbers tend to use acetylene-air torches instead of propane, because they are hotter yet.
What gas to use for brass joint?
I would recommend the use of MAPP gas instead, it burns hotter than straight propane, and depending on how much metal you have to heat up just to get the joint hot enough for the brass to flow, you might need the hotter flame to do it.
Can you use butane on a propane stove?
It burns. At a similar flame temperature. I most often switch back and forth butane for propane and the reverse on camping and backpacking stoves, burners, etc. Which are also pre-mixed fuel-air flames like a propane torch is.
How to use a propane brazing torch?
However, with practice, it becomes easy. Firstly, turn the propane pressure regulator to set its working pressure. Secondly, open the propane cylinder slowly to half turn. Thirdly, adjust the propane needle to working pressure and then close it.
What Is A Propane Brazing Torch Kit?
A propane brazing torch kit is a device that uses propane gas as a fuel to join dissimilar metals. The propane gas combines with oxygen to provide a high-temperature flame that is ideal for joining different metals. There are many brands of these blowtorches in the market, including Bernzomatic TS8000 and the Red Dragon VT 3-30 C, which are among the best.
How to braze metals together?
Secure the two parts using a vice so that they do not move during brazing. Using the propane torch, heat the two metals that you plan to join until they reach optimum temperature. Apply brazing wire to the joint and heat it until it melts into the seam. The two metals will be firmly joined once they cool to room temperature.
What is a fuel flash arrestor?
The fuel flash arrestor prevents the reverse flow of propane gas in the supply line which can lead to an explosion. Similarly, the oxygen flash arrestor prevents the flashback of oxygen within the hose.
What is a propane regulator?
The propane regulator is a gas flow regulating the device. It adjusts the pressure of the propane in the hose. In the same way, the oxygen regulator controls the flow of a gas in the supply line.
How to clean metal before brazing?
The metals to be brazed need to be thoroughly cleaned before the process begins. Use sandpaper or steel wool to remove the oxide layer, acetone to clear oil or grease, and soap and water to remove dirt from the metal surfaces. Rinse the metal surfaces with water.
What is a nozzle in a gas furnace?
The nozzle is a metallic tube that directs the flow of the burning propane-oxygen mixture to the surfaces being joined. Its size controls the rate of flow of the gas. The nozzle type also determines the shape and size of the flame, thereby varying its intensity.
