During a session, one side of the array acts like an anode and the other as a cathode. Therefore, one side of the array will actually lose material to the other side over time (this process is also known as electroplating). You may see “pitting” of the bars on each array, on one side only. The “pitting” that you see is where the anode side is losing material to the cathode side of the array.
Eventually, this is why the entire array will need to be replaced. Our 10th generation array is designed to withstand this phenomenon and extend the life of the array and Turbo Plates by allowing the user to replace parts in less than five minutes without tools.
