Can you plug a 230V 50Hz welding machine into 220V 60Hz outlets?

FIRST THING I WANT TO KNOW THAT WHETHER YOU ARE TALKING ABOUT INDUCTION MACHINE OR SYNCHRONOUS MACHINE?

IN INDUCTION MACHINE, RATIO OF VOLTAGE TO FREQUENCY MUST BE SAME FOR CONSTANT TORQUE. IN THESE CASE AS YOU CAN SEE, V/f RATIO IS NOT CONSTANT THEN INDUCTION MOTOR WOULD NOT RUN.
