I am a contractor, not an electrician (so any pros are free to correct me) but my understanding is that you need to first determine what amperage circuit you need based upon the wattage of your welder.
With volts x amps = watts, this means that at
240volts x 60amps = 14,400 watts
However, circuit should be loaded only to 80% of the potential, or 11,520 watts.
As long as your unit draws less than 11,500 watts a 60amp circuit is sufficient. Anything equal to or 'smaller' (numerically ie #3/#2) than a no. 4 wire is acceptable.
If your unit draws signifcantly more or less wattage, the circuit amperage and associated wire size will change accordingly.
