Microwave welding machine


Hello everybody. Not a single work with metal is complete without welding work. Welding cuts and joins metal structures. But a good welding machine costs a lot of money. And buying cheap does not make sense, because it still makes flour with such devices. But the welding machine can be easily made do it yourself. There are many articles on the Internet on this topic. Well, almost all of these homemade devices are very weak. Or powerful, but huge, heavy and uncomfortable.

But there was one option for manufacturing a welding machine, made by its author channel kreosan. It differs from others in compactness and power. Today I will show and tell you the whole process of manufacturing this device. If something is not clear, then at the bottom of the article there is a video where everything is shown in detail.

Let's start, for manufacturing you will need:

1. Two transformers from the microwave
2. Cable or wire of large cross section
3. Electrode holder
4. Epoxy adhesive
5. Grinder, hammer and tools

Step 1. Production












This device is very easy to manufacture, so I will describe everything in one step. In order for the device to turn out powerful and transformers need powerful ones from 1200W. For good electric welding, power is needed within 4000 watts. So if you remove the current shunts, then the power of the two transformers will be within 3900 watts, this will be enough. The secondary winding is removed from the two transformers and the current shunts are knocked out. Further, a cable is wound in place of the secondary winding. 54 turns are made and two taps at 40 and 47 turns so that the voltage can be changed. Then the transformers are glued together, as shown in the photo or video. Connects to the cable, electrode holder and ground.

Step 2. Testing





Everything, the welding machine is ready, now you can test. Testing this homemadecan watch on video. There should be no insulation on the wire or cable, because the transformer is heating up or there must be some special heat-resistant insulation. There are doubts about epoxy glue. And so the welding turned out powerful, judging by the video.

I do not understand electronics. If there are concerns about the assembly and operation of this homemade product or improvement, then share them in the comments. This can be done, thanks for watching. If the article is suitable, then we like it.

Creosan, seriously ...

Briefly.



Well, basically everything)
At least two trance from them. And working explosives trance.
And Kreosan is the hiper that you wanted .... It seems from shit and sticks, but expensive.
Do you have to go and buy two new microwaves for this?))))

I repeat for the third time, it is better to buy welding, I agree with this. But if you have all the materials for the manufacture, there is no welder, welding, money, etc., and you need to urgently weld something, then this homemade product is like an option.
deals with garbage cheaper to buy welding in a store than two microwaves to buy
It’s better to lend someone a welder one time ...)))))

Especially since
The video shows how the author buys a copper bus, and pays 3,000 rubles for 2.5 kg! Plus the cost of welding ends, nests for them, etc. etc. ... smile
So no, I'll regret 50 bucks

If there is no money, but there is all the materials and you need to urgently weld some detail. That I think will come down, one at a time. And it’s better to buy an inverter
No need to try anything ..
Firstly - this, all the same, is not welding, but pampering.
Secondly, since the inverters began to cost a penny, I can not imagine who can desire a transformer, and why? !!!
Indeed, even such "pampering" will load the network much more than a full-fledged 200 Ampere inverter welding machine, which confidently cooks with a constant (!!!! ... only welders will understand))) with a huge five-electrode current, while consuming no more current than an electric kettle!
So no, I will regret 50 bucks and collect an incomprehensible transformer misunderstanding, which will be with spitting and shooting (break !!!) to cook for no more than a few minutes only with thin electrodes (and by no means any). And at the same time, look for a socket with good wires, and turn off the refrigerator, because this is a misunderstanding, what does the network do.))))
Gone are the days. Then winding transformers, BECAUSE IT WASN’T !!!

I would not risk it and buy a factory machine. But if there are materials and some knowledge in electrics, then you can try.
then go with red bread after such “masks”
Further to the place of the secondary winding, is wound cable.
nea The cores are not pulled together, the welding ends are connected to nozzles, etc., etc. ... nea
