Start to finish build of a widebody PA-18 Fuselage by the Pro's at Airframes Alaska. Fully TIG welded and approximately 180-240 man hours of labor condensed into 6 minutes and 25 seconds.
I dont think a foot pedal is a good idea for this type of welding. You lose your mobility since you can only weld sitting down most of the time. A hand switch is a must better option. Some of them you can dial in while you weld. This is 1950 welding. At least they Tig weld the chromolly. If they post heated the frame in an oven they would get back 70% of impact and tensile strength. It will make a difference when you hit a mountain side. But I guarantee you they wont tell that to their customers.
Great at making airframes but know little about you tube videos .. All the greats on here do not use rock music and they all have narration , they turn the music off and talk some . My favorite music is rock but few seem to understand it doesn't go with airplane videos .. at all ... it becomes super annoying .. Were on here to learn about airplanes and get our music fix elsewhere
