"YOU HAVE TO CUT IT INTO SHORT LENGTHS, DUMMY!"
This comic is quite dated and some may not understand the humor.
Most welders today never arc welded with bare wire and would not recognize it in rolls.
But "The Old Welder" turned 90 in 2009 and remembers a lot of things most of us never heard of.
Besides the bare rod the old motor generator DC welder appears to be a WWII SAE welder.
I had to rewire one of these from 480 to 240 volts once.
While these were a VERY standard welder they did not come with marked terminals, wire pairs or voltage change instructions.
It took a good bit of electrical detective work to figure it out.
The "Old Welder" man be old but much of the equipment he cut his teeth on is still in operation.
