The invention belongs to the field of welding and relates to a gas shielded welding molten drop transition control device and method, in particular to a gas shielded welding molten drop transition control device and method based on the molten drop resonance principle. The gas shielded welding molten drop transition control device and method based on the molten drop resonance principle aim at manyproblems existing in gas shielded welding molten drop transition under a low current. The gas shielded welding molten drop transition control device comprise first guide wire couplings, second guide wire couplings, third guide wire couplings, a cam guide wheel mechanism, a cam driving mechanism and a conductive nozzle. The first guide wire couplings, the second guide wire couplings and the third guide wire couplings are sequentially arranged from left to right, the second guide wire couplings are mounted at the upper end of the cam guide wheel mechanism, and a cam in the cam guide wheel mechanism is connected with the
