Questions and Answers: Q: what is the material? A: (drug cored aluminum) Q: How many degrees do you need to reach? A: (400 degrees, only high and not low) Q: What materials can be welded? A: (almost any white metal, same or dissimilar) Features: 1. No need solder powder. No other materials are required, and it is easy to use. 2. Light weight and easily carry, stable performance. 3. Great welding effect, with low melting point. 4. Great weldability and corrosion resistance, high thermal conductivity, high electric conductivity. Instructions： Step 1: polish the surface through physical cleaning. Step 2: heat the base metal surface at the welding place until the temperature reaches 380 ℃ - 400 ℃ of the working temperature of the welding wire. In this way, the welding wire can be melted by the heat conduction of the base metal. Do not burn the welding wire with flame. Also, the welding wire can flow and penetrate into the metal capillaries well only when the base metal surface temperature is sufficient. Step 3: when repairing thin aluminum, just heat the aluminum base metal to the appropriate working temperature, and then use the welding wire to rub and melt back and forth to form a weld. Only use the metal brush to fill the molten welding wire in the welding area to form a weld. Product: Aluminum Welding Rods Material: aluminum alloy (flux cored aluminum) Melting point: about 400 ℃ Diameter: 1.6mm Length: 33 cm Applications: For Aluminum, Iron, Copper material Operation attention details 1. The surface of base metal must be cleaned. Clean and weld immediately 2. The temperature of the base metal must reach 400 ℃, including the temperature of the base metal during welding, which can be high or low. 3. It is forbidden to burn the welding wire with flame deliberately. After the temperature of the base metal reaches 400 ℃, the welding wire will naturally melt by heat conduction of the base metal.
