Pakistani basic welding machine build -- pretty amazing!

Watch them wind the transformer and fabricate the taps. Street vendor engineering at its finest.

One of my customers, make the speciality insulating paper, used in all kinds of transformers, while he might marvel at the ingenuity, he would take serious exception to the use of plain cardboard.
DeadNutz:
They are skilled craftsmen with limited tools and they make a product in demand or they wouldn't be doing it. But you don't want to let the magic smoke out of that welder.

LOL -- Yeah I saw that he took what looked like some leftover thick glossy poster paper to insulate the windings. Sketchy to be sure, but given the country, the purpose, and the market, these guys are pretty damn resourceful. They have to figure out wire gauge, winding turns, and power factor to produce the desired output at the taps for a given size machine. Pretty cool to see it done with very basic and mostly homemade tools.
Found a vid on how these Pakistani craftsmen calculate the windings --
