Since earlier least year, my grandfather and I have been trying to get his old wire welder to work.
The welder used to be in his old plumbing shop, and we found that someone had used it a little bit and put in the wrong size wire. After we changed the wire to the right size it still wasn’t going through the tube. So we took it to a guy that fixes welders at his house and when we came back a few days later, he had found that the tube the wire goes in had a kink in it. So after he changed it, it works really good. After practicing a bit with some scrap pieces, I fixed a piece of our younger brothers power wheel car that had broken when they were off roading in the front yard last summer.
