Features: 1. General welding wire: Introduced a basic but powerful aluminum rod designed for perfect welding, the universal welding wire 2. Universal welding wire is a set of simple welding rods specially designed for powerful and perfect welding. It is made of high-quality aluminum. It is odorless and super durable. 3. Good welding effect and low melting point. Excellent solderability and corrosion resistance, high thermals conductivity, high electrical conductivity and excellent processing performance. 4. No solder powder needed, no other flux powders using aluminum alloy as flux, and no salt-based coating. Very convenient and easy to solder. 5. Long service life, suitable for welding or surfacing welding of alloys with high strength, good forgeability and corrosion resistance. 6. Light weight, small size, very easy to carry. Universal welding wire can also be used for argon arcs welding and filling materials of pure aluminum, connection with aluminum bus bars and guide rods or electrolytic aluminum plants, as well as electricity, chemistry, etc. It is very simple to use.
