@romanci38: 🆕 New project! Mini spot welder with easily replaceable battery! 🔋⚡ In this video I show you my latest invention: a portable mini spot welder, battery powered with a quick and easy system to replace it when necessary. Compact, practical and perfect for small jobs on sheet metal or for those who love to experiment with DIY projects. This is a personal experiment, not a commercial product. #MiniSpotWelder #DIYWelder #Technology #DIYProjects #Inventions #LifeHacks #DIYEngineering
