High frequency casting machine for melting precious alloys and Co-Cr and Ni-Cr. It minimizes operato intervention and the consequent risks, enabling a fully automatic working cycle that uses a microprocessor to control the times and the power given by the generator. A sophisticated electronics can keep the corrected power for maximum performance without risk of overheating of the alloy and the fluorescent display shows the parameters used. The cooling liquid circuit is independent. The device offers the maximum ease and safe of use.
