    STUD WELDING is a high-speed metal fastening process in which a metal fastener can be applied by a welding arc to another piece of metal.

    THE PROCESS OF STUD WELDING: The welding stud is placed (with a hand tool called the Stud Gun) in contact with the base metal, a weld arc is drawn which melts the welding stud base and an area of the metal work piece for metal fastening. The welding stud is then forced into the melted area and held in place until the metals re-solidify. This high quality fusion arc weld is complete in milliseconds and is accomplished by one of two major methods.



    The kids had an old F150 monster truck Power Wheels toy that had a dead battery. I charged the old 6 volt battery for about half of a day. After charging, it wouldn’t light up a test light, much less turn a motor in a big toy truck. I took an old car battery and installed the power wheels battery connector to the terminals of the car battery. I used a couple of ratchet straps to hold it down. The 12 volt car battery turns the 6 volt motor twice as fast. My youngest daughter loves it. She goes pretty much full throttle on it all the time. My oldest daughter likes it, but is very cautious. She pumps the pedal causing a surging that is almost sickening to watch. Thanks for watching! Please subscribe.
