How to use oxygen torch and skill video

The use methods and skills of oxygen cutting torch are as follows:

When using it for the first time, it is recommended to use a relatively sharp soldering iron of about 30w. The choice of welding wire depends on the individual and can be judged according to what is being welded. It is recommended to buy rosin for flux (you can find a small piece to crush and dissolve it into rosin water with high-purity alcohol). For small solder joints, you can find something to stick on the solder joints, which is very useful.

When starting to use, first determine the type of your own gas welding torch, whether it is electronic ignition or external ignition. If it is an external fire source, pay attention to safety. First, open the gas opening valve of the gas welding torch to the minimum, and then ignite it carefully (the left hand holds the gas welding torch above and the right hand ignites it below the nozzle of the gas welding torch).

As for how to prevent the welding head from oxidation, it is usually a new soldering iron. It is best not to weld for the first time. When the heat can melt the tin wire, evenly coat a thin layer of tin on the welding head to protect the welding head from oxidation. After cooling, add gas for later use.

After use, the welding head is plated with a layer of tin, and then it is dead. This can effectively prolong the service life of each welding head, and it is not easy to oxidize. Beginners should be careful not to ventilate and heat for a long time when using electric soldering irons, especially non-constant temperature electric soldering irons. The first temperature is too high to control, and it is easy to burn out components.

Extended data

principle of operation

The welding torch uses the heat generated by the high current and high voltage of the welding machine to gather at the terminal of the welding torch to melt the welding wire, and the melted welding wire penetrates into the parts to be welded. After cooling, the welded objects are firmly connected into a whole. The power of welding gun depends on the power of welding machine and welding material.

The welding torch has the advantages of qualified welding effect, safe welding, high speed, reliable performance, simple maintenance, convenient adjustment, no power consumption, steel saving and low equipment investment. The welding torch gas pressure welding can easily complete the welding work of flash welding and electroslag welding, and the quality and benefit are superior to the latter two sets of equipment.
