Rod feeder

I realized that I wasn't quite sure what my left hand was up to in the drawing yesterday, so I examined it a little today. Something similar to holding chopsticks, but the thumb and forefinger can tweak back and forth to keep feed of rod for welding. Similar activity today, but more TIG welding than gas. The argon gas used in that has some kind of sweet scent added to it I think.

I wonder if those folk in Hokkaido are pulling my leg. One would have thought that the way oil is running low the greenhouse gas emissions would be down to about half anyway by 2050.
