Chế Máy Hàn Sắt - Hồ Quang với biến áp lò vi sóng

Welcome to my channel Today we will build a metal detector From the old soldering iron I use the 800E, the big one There are 2 types, this is 800E, the small one, it is a little lower And it's smaller But this type you can buy from 150,000 to 200,000 VNĐ per piece I will need 2 soldering irons 90% of these soldering irons are soldered on the bottom This is 220V We will keep this part This part is usually called the circuit Now we will cut this part And hammer it Wait for the soldering iron to finish When hammering, don't cut this wire To protect this part The circuit is 220V We don't want to affect it Now that we have hammered these 2 So it's done The soldering iron has finished these 2 Remember to remove the soldering iron To clean it After removing the soldering iron We will measure its ohm Measure 3-4 ohms 3 ohms That's all Now let's find the soldering iron We can use a soldering iron like this This type is 4mm, but it is a bit weak I will use this wire 6mm The hole is about 3mm Now we will cut it The hole is about 3.2mm This wire is about 6-7mm That's all 2 wires Each wire is 7m long Now let's wrap it Wrap as much as you can That's all This wire is very hard Wrap as much as you can This wire is about 2m long We will make it into a cable That's all Now let's connect these 2 together That's all Connect these two wires Now we will make a wood box Measure the ohm At the time of testing, you have to be careful not to shake The soldering iron The two ends of the wire are a bit weak If so, you will replace these two wires So that the two ends of the wire are parallel to each other So that the current of the two ends of the wire is not in the opposite direction The outside of the wire is clear and the inside of the wire is not clear That's it 22V, 22V will not turn on Comfortable We will measure the current of the two ends of the wire I will leave about 200A 188A Keep it for a long time I will press the button to keep it I just went up to 190A but I didn't keep it So its power is almost 200A Now I will close the box That's it Now go to the house to test It's been a long time If I count the days, I will do it in 2 days Because I still have to wait for the paint to dry The next day I will make a frame for this Let's go You can use a 2.5mm router 3.2mm is a bit weak We can only use 2.5mm or 2.5mm 2.5mm
