On a Mitsubishi MV1200R has anyone tried using an off brand or cheaper wire to cut parts? I use genuine Mitsubishi wire now .010 dia. A salesman is trying to sell me cheaper wire. But he has never used a wire edm, he is in sales. I am content with the results I am achieving now. We don't need high accuracy. +- .0005 to +- .001. We don't need a great finish either. We have odd shapes so we use a wire. We stamp aluminum. We don't have unattended machining either. So rethreading is not an issue.
