Hakko T12 Soldering Iron Controller + Handle + Tip. I made version 1 in January 2016.
This was made in Korea and used by many people. It has recently started to be used in various countries.I used Arduino to implement precise control functions. Automatic spot welding, and FET check function, Alarm, etc.
As shown in the picture, a basic spot welding cable is provided. A Soldering iron handle and T12 tip are provided. You need two additional things. For Spot welding : RC battery (3s 5000mah 25c) or 12v car battery (80100AH). For Soldering Iron : 24v 4A, 19v Notebook adapter or 4s battery pack (DC jack : out 5.5mm - inner 2.1mm).
OLED screen shows detailed information. Encoder can easily change the settings. You do not have to press the switch every time.
When the spot welding tip is pressed nickel strip. After 0.8 seconds, it is spot welded. 0.8 seconds is the default. Each battery has different performance. Even if you forget battery charge, It tells you when to charge.
The voltage value can be adjusted. Electricity raises the temperature of the part. It can get hot if you want strong welding performance. It may also inform you of the failure of an important component FET.
You can control up to 450 degrees. Preset : It has 5 presets. Video on how to use it. Automatic Spot Welding Test (It include soldering iron) for 18650 - YouTube. Video will open in a new window.
