Arc melting copper

1. Generally, it will not be bad, unless the response of each other
2. The cooling amount of copper molds is limited, the amount of high -temperature metal solution is required to provide you with
3. You can spray off the surface of the copper mold and take off the surface of the copper mold.Model, sell on the Internet, cheap

Generally not, if the water flow is enough

The melting alloy is copper to melt. Try not to do that. You can consider suspended melting or induction melting. It is not easy to have good equipment and cherish it.

As long as the alloys and copper do not respond quickly, the copper heat conduction is good and cooler
