Welding simulator with realistic effect

Arc welding simulator

How to use it?

This welding simulator is very realistic. It uses white and blue LEDs to give a bright pulsing light similar to that of an electric arc welder. The circuit can be hidden inside a building on a model railway layout or diorama to provide activity and realism. The realistic effect is achieved by random length of flashes and a random length between flashes. Small size approximately 20mm x 20mm x 10mm (L x W x H). Operates from 6 to 20v smooth DC or 9v battery.

+ V is the anode
GND is the cathode
