120V MOT transformer on 220V for spot welding machine? Answered

Hello i'm making a Spot welding Machine using a microwave transformer i'm removing the secondery coil to replace with 2 rounds of very thick wire for the output . the only problem is the transformer rated for 120V input Will it matter if i connect the primary to 220v ? i'm replacing the secondery anyway ?
