Finally, welding simulation that looks just like the real thing! A bit of shameless back-patting, but we believe it is warranted. These simulators are configured for connection of two LEDs to accurately reproduce the varying intensity, intermittence and slight color changes just like real welders. Our Nano LEDs are perfect for reproducing these effects. N8064 is the arc welder and N8064B is the gas welder. See Connecting under More Info to the right, for product details.
