Gas burner is a very useful tool that is an indispensable for many masters. With the help of the burner, you can quite reliably and, importantly, it is easy to combine various details. It can be not only metal. The burner is connected by parts that melt at a temperature of about 1100 degrees, but not more.
So, the gas burner has the simplest device. This is primarily a nozzle from which fuel is supplied (gas), with a handle and a regulator. The nozzle is connected by a thin flexible hose with a cylinder in which the gas is located. Gas in the cylinder is always under pressure, so you have to be careful. For example, you can not put a cylinder next to heaters or open fire.
Work begins with the preparation of parts. For example, you need to combine two metal blanks. They should be fixed. The fact is that in the process both hands will be busy with a gas burner. Rather, one hand will hold the burner, and the other — a rod with solder. According to the details, it will be difficult to pay attention during work. That is why the details are in advance in the right position and so that they do not move during the connection. For example, for this you can use a vice.
Also, the parts for soldering need to be cleaned so that the connection turns out to be truly high-quality. That is, the parts are pre-washed, cleaned or treated with some special solutions.
Now that everything is already completely ready to work, you can turn on the burner.
First unscrew the valve in the upper part of Bologna. The gas from the nozzle will not leave yet. After that, light a lighter or match, bring open fire to the snot and open the gas supply on the handle. The flame will flash.
When ignition of a gas burner, it cannot be brought to other people or to some flammable objects.
When the gas lights up, the pressure must be adjusted correctly. The gas stream should be thin and «elastic». Now you can start soldering.
The secret of good soldering with a gas burner is the heating of the details as uniform as possible. That is, do not hold the burner, directing it to one point. It is better to drive flame a little in the connected area.
By the way, the flame has the highest temperature inside, where it is darker. However, for most cases, it is enough to put the external edge of the flame on the connection. So the workpieces will heat up more grades and more uniformly, which will make the connecting seam better and stronger.
When the blanks are heated, take a bar with solder and put it in the right place. Under the action of the temperature from the heated connection, the bar will melt and fill the seam. Sossor code will freeze, the details will be connected into one whole, and they can be used further as intended.
The gas burner is necessarily turned off, the valve is closed in the upper part of the cylinder and cleaned in a safe place where this kind is usually stored.
