This welding room is a big project. Things to learn were how to set up grounding rods, install a subpanel, wire 240 volt circuits, and to work with PVC conduit. The electrical work is done and the sheathing is installed. The next job is to cover the walls with sheet metal so the welding sparks do not start a fire in the wooden shed.
There are two lighting circuits. One is a conventional setup with a switch on the outside wall, an exterior light, and two interior lights. This is adequate for most tasks. The other lights are plug-in LED strip lights four feet long. Four of them stuck up between the rafters do a great job of lighting the area where the welding bench will go.
