I designed and made a welding machine out of thin card
Here is the design as printed out by my CAD program.
I needed a person to operate my welding machine but the only man I had kneeling was a trucker that I think is meant to be changing a wheel on a truck.
I made him a welding mask out of some insulation stripped from some wire.
I gave him a blue boiler suit and then grubbied that up and painted on some leather gloves.
He now holds the end of the wire which supplies current to the white LED.
I ordered all the electronic components from mouser.com
Since I did not have the printed circuit board I had to map the circuit layout onto a 1/10" prototype board. I then drew where the connections had to be on the back using a pencil.
I found a plastic box that was a perfect size and I cut the board to fit
The power supply to the simulator is switched with a K84 module to that I can switch the welding on and off from the computer.
