Triple Welder Kit with sequenced operation to create a great welding or contruction scene.

The BK-115 Trip Welder Kit has 3 separate welder flash super bright white LEDs that produce simulated welding flashes. The circuit is programmed to simulate a welding scene where multiple welder are working. The three LEDs will run at seemingly random times where sometimes one welder is working, sometmes two and sometimes all three are working. The welding time at which welder(s) are working will randomly change to give the effect of a real life work scene. A pause time can be selected to stop the welding action so that there is no one welding for a while.

Great for contruction or repair shop scenes. The welder LEDs can also be located far appart if desired to simulate multiple scenes accross the layout.

Kit requires assembly, but can be purchased assembled and tested as an option.
