Tim Barker shows the appropriate technologyclass the basics of welding. Starting with an introduction to a MIG welder, Tim walks the class through the parts, how it works, and trouble shooting and safety.
He also goes over different applications, and different types of welds on different types of metals; how to hold the gun; and best practices.
Then the class heads outside to watch some demonstrations by Tim; and students then get to try out some welds themselves.
