F wave properties include: 1  amplitude (ÂµV) - F wave height. 2  duration (ms) - length of F wave. 3  latency (ms) - period between F wave and initial stimulation.
LITCHFIELD IS A SMALL TOWN of approximately 8,000 people located in northwestern Connecticut. Founded in 1719, Litchfield has a rich history. The town was the home of the first law school in the United States as well as an early school for girls. At the end of the 19th century, Litchfield residents became leaders in the Colonial Revival movement.
In 1925, it produced its first welder, which started Hobart Brothers on the path to becoming a preeminent company in the welding industry. It also became a prominent supporter of welding education with the establishment of the Hobart Institute of Welding Technology in 1930. The school became a separate non-profit entity in 1940 and has since trained more than 90,000 welders.
