How to spot weld a capacitor?

Most spot welders use two points near each other or on each side of the workpiece. The current from the capacitor is probably just absorbed by the relatively large piece of metal. The second video below from [American Tech] shows a 500F capacitor doing spot welding with little more than two wires and it seems to work.

How does a capacitor work?

Its working principle is that the capacitor releases a large amount of energy in a short time to form a strong arc, which quickly welds the metal materials together. This welding method is fast and suitable for welding tasks that require high precision and high efficiency. It is often used for welding battery packs.

What temperature should a spot welder be used in?

This product is recommended to be used in an ambient temperature range of 15°C to 50°C. Temperatures outside the use range will affect the spot welding effect and service life of the spot welder. 4.

How to use a spot welder?

How to use a spot welding pen?

1. After turning on the power, press and hold the ON/OFF Key/Switching key for 2 seconds to turn on the power, short press the ON/OFF Key/Switching key to switch the setting options, the cursor stays on the required setting item, and short press Adjustment key to adjust the parameters. 2. Insert the spot welding pen, the device displays "OK.

How do I start welding?

You can start welding. It is recommended to perform a welding test before formal welding. If you need manual mode welding, please touch the smart pen button to trigger welding, or use the foot switch that comes with it. Note that you need to connect the connection line to the trigger interface of the device first.
