Better, welding the disposable successful effect, due to the Aluminum Electrodes tubes melt peeling tool point is too low, the second heating, the tubes can easily deformed.

2, the electrode must be applied evenly flux, in order to ensure the quality of solder joints.

The torch flame is not too long and must be with micro fire heating tubes easily melted or dispersant.

4, the welding is completed, to wait for a dedicated slurry two nylon yarn, cement repository can contact only three minutes tube cooling, otherwise the solder joints leaky.

Welding time is not too long, easily lead to melting or thinning of the aluminum tube wall due to the melting point is too low for too long suppressed easily leak.

6, the liner must be placed wet towels to protect the place, because the the Welding Wires space very narrow, so be sure to pay attention to the protection of the refrigerator

7, the electrode can not be heated with a welding torch first dipped into the solder powder because this electrode melting point is too low.
