It will, there are only 2 Dinse pin sizes, either 9mm or 13mm.
9 is not used very much, some plasma machines use it as the ground cable, and some really small and portable tig machines do use them as well.
However, the small 9mm size plug is almost always coupled with a 25sqmm max cable.
Most serious machines use 13mm Dinse, and cables 35sqmm and up
The 50-70 and 35-50 number just denotes the size of the cable which can be mounted at the non pin end, but on anything large enough to take a 35 sqmm the pin end is alway the large 13mm pin.
