From what I saw on YouTube, you just touch, then zap. Now that you mention it, I don't remember seeing any plastic near the metal parts that they are welding. :-) On 2025-01-12 17:51, Don Tai wrote:
I stick weld (SMAW arc weld), heating the metal up to 6k C. This will obliterate all the plastic nearby. You will need to disassemble the screwdriver to have any hope of repairing it. There must be another way to put your locking bit holder on to your cordless screwdriver. Do more research. Also is the metal you want to weld ferrous, like can you stick a magnet to it?
My recommendation is to buy a new cordless screwdriver, unless you wish to spend more time figuring out how to disassemble it. The battery is also close by, which would also be a concern.
It is winter and f-ing cold outside, so I'm not welding. I'll be batching up jobs when spring comes.
