Frequently Asked Questions
Q: What is this DIY spot welder control board compatible with?
A: This control board is specifically designed for microwave oven transformer (MOT) based DIY spot welder kits. It works with standard transformer spot welding machine setups commonly built by hobbyists and makers for welding battery tabs and thin metal sheets.
Q: What is the difference between the 41A and 100A specifications?
A: The current rating relates to the control capacity of the board. The 100A version supports heavier-duty transformer setups and thicker materials, while the 41A version is well-suited for lighter MOT builds and thinner metals such as nickel battery tabs. Choose based on your transformer's output capability.
Q: What does the dual pulse function do?
A: The dual pulse function sends a short pre-pulse before the main weld pulse. This pre-pulse helps clean and prepare the metal surface, reducing oxidation and contamination at the weld point, which results in a stronger and cleaner weld joint with less spatter.
Q: Is the LCD display easy to read and configure?
A: Yes. The included LCD display board shows your current and timer settings in real time, making it straightforward to adjust parameters and monitor your weld configuration at a glance — even for first-time builders.
