HTP America, Inc.'s 70-minutes DVD Welcome to the World of TIG Welding covers the entire TIG welding process, from running a bead to butt, lap and fillet welding in both steel and aluminum. It also covers TIG torches, remote amperage control, different arc starting methods, slope up and down as well as post flow, final current and pulsing. The video provides an in depth discussion on AC frequency and balance, two features found on inverter TIG welders.
