What size wire for 100amp. 12vdc?

A #3 copper wire with an insulation rating of 75 or 90 degrees C is rated at 100 and 110 amps consecutively. As for the voltage, wire is usually rated in 300, 600 and 1000 volts. Any three of these insulations factors will handle 12 VDC.

What size wire do you need for 440 three phase welder on an eight foot run?

The wire size depends on the amperage, not the voltage. The fact that the welder runs on 440 volts does not affect the wire size! You need to ask this question instead: What size wire do you need for a three phase welder on an eight foot run if the nameplate amps are 45A?

What wire size for 100amp load for distance of 1000ft?

At that distance you will have a voltage drop of 81.25 volts if you use the recommended #6 wire on a 240 volt, 100 amp single phase circuit. Therefore I recommend you contact you electric utility and let them figure the voltage drop and the size wire required to safely run this distance. Using too small a wire can damage the electronics at the end of the run.
