Copper heating to 600 degrees, why the surface will have zinc precipitation, what method can be solved?
I think the first check whether the wire connection, if the circuit breaker, so only zinc itself to form a loop, behoove above was copper. Zinc in zinc, check whether the higher purity, without high purity, containing no copper
