Simple Microwave Welding Machine

Making a simple welding machine from the microwave with your own hands

We take a transformer and fix it so that it does not move. We take a hacksaw for metal and cut off the secondary winding on both sides of both transformers. If you decide to repeat, be careful not to damage the primary winding.

Then we drill the winding with a drill with a metal drill, thereby removing the internal stress of the metals so that it is easier to knock out the remains.

We knock out winding residues.

I reeled at 17-18 turns for each transformer, 6 rows high and 3 layers thick. uploads / posts / 2017-11 / medium / 1509952742_13.jpg "style =" max-width: 100%; "alt =" Welding machine from a microwave oven ">

After winding is completed, we connect 220 V high-voltage windings in parallel. I used automotive tips, insulated with shrink tube.

I turn on the entire structure to the network, and measure the voltage on the secondary, which I wound. The result is about 31-32 Volts.

Microwave WhenI will use 2.5 mm electrodes for welding and make two 2 mm pieces of iron.

In principle, you can cook, but not for a long time, because the transformers get very hot and therefore after each electrode you need to allow the device to cool down. metal does not work very well, because it simply cuts. To reduce the current in the circuit, you can use a choke or a balanced resistor. In the role of a resistor, you can take a piece of steel wire, including it in the low-voltage winding circuit, and pick up the current already by its long, setting up the arc burning efficiency. I am satisfied with the result, it is quite suitable for household needs, considering that I actually got free.
