When I wanted to learn TIG welding, I saw that the torch could get very hot and deteriorate. So why not make water cooling box.
One day, by a lucky chance on the sidewalk, I came across a cooler for a laser engraver ! Lucky me. After a few hours of troubleshooting and repair, the cooler was back up and running.
But this boy needs some tuning than just a colling system. I wanted to add preflow gaz timing, postflow gaz timing, arc cut-off switch and some fancy icons on the oled screen.
