you can but the tc wires don't solder.

the pins of the plug are made of the same alloy so there is no cold juction, a
juction occurs when the metals change usually atthe socket in the meter. If you
use "ordinary" metal for you adapter pins then you will create a cold juction
at that point and some more in the socket itself. This is not a problem as long
as all the juctions are at the same temperature.

Some tc adapters have all the signal conditioning circiutry inside them so they
can be used with a standard meter, I dont know if that applies to the 80ak.
