Is this 100% copper wire

I change one of the connections and it was copper wire.

Will this handle the old classic Lincoln buzz box?

Yes-the ends fit. I use these because they're cheap long cords for a little DC box that works 115a/250 for stuff around the house/yard but max out my welding max 110 dc amps for small jobs. These cords are only 10 gauge-I have a the fatter 6 gauge cords for the high amp jobs-the 6 gauge cords are twice as heavy and expensive.

How long can I run a machine on this? Looking to use it to connect to my pool heater (wont get wet) but ill need it to run for 30hrs

It's a good, well-made cord. You should compare cord AMP rating to your pool heater AMP rating to see if it is big enough.

is 10AWG really rated for 50A??

No. You should be using 6AWG minimum for 50A
