Making a Simple Battery Spot Welder - DIY Battery Spot Welder


 Making a Simple Battery Spot Welder - DIY Battery Spot Welder

Only 12v dry battery and motorcycle starter relay are sufficient to make this spotting machine. There is no need for materials such as transformers, capacitors, etc. The first 2 minutes of the video are the construction phase. The next is the testing and spotting section. The materials are as follows;


1- The dry battery must be at least 9AH. This is not possible with batteries below 9AH. It can also be 10AH or 12AH. However, batteries with higher amperage or car batteries (45AH and above) may damage the battery. It may puncture the battery cap. The ideal one is 9AH. The battery you will use is also Make sure it is fully charged.

Additionally, the battery must have a power of at least 200A. You can find this information by going to the official website of the battery you have.

2- The starter relay is for a classic scooter. I bought it from the industry. It can be found in any motorcycle repair shop. The one I use is the same one here.

3- The cable must be at least 2.5mm. It is called single-core installation cable. It can be found in electricians.

4- There are two types of battery terminals. They are available in electronics stores. The one for 6v batteries is thin, pay attention to this. When purchasing, specify that it is for 12v dry batteries.

5- The strip used is 0.15mm nickel strip. This is the most ideal. The width can be 5mm or 8mm.

6-Adapter/transformer/power supply etc. This does not happen with devices. No matter how powerful they are, this type of devices interrupts the current in this system. It does not cause spotting.

7-The name of the green button is 'button'. It is available in electronics stores.

8-Lipo battery, drill battery etc. Not with batteries.



It must be a 9ah or 12ah lead-acid battery.I don't recommended car battery or high amps battery.It may destroy the cell head.For relay, search on aliexpress this ; ''12v solenoid relay starter''
