There is no need to use other flux powder with aluminum alloy as the welding core and coating as the salt base. These aluminum welding rods can only be used to weld aluminum. The low temperature flux core welding wire is made of premium nontoxic, odorless and durable aluminum. The easy melt aluminum welding sticks are suitable for welding or surfacing welding aluminum, aluminum alloy, aluminum-magnesium alloy and other white metals with high strength, good forgeability & good corrosion resistance. Suitable for welding a variety of materials, metal universal welding wire 1.6mma can weld almost all white metals, including aluminum, aluminum alloys, cast aluminum, aluminum-magnesium alloys, stainless steel or other metals, once used, never fall off and never crack Ectric conductivity and excellent processing performance. excellent Corrosion Resistance. minimize the Distortion of the Starting Material During Welding. What is the Welding Principle of Low-melting Aluminum Welding Wire? Low-melting Aluminum Welding Wire is a Common Argon Arc Welding Electrode. The Argon Arc Welding Technology is Based on the Principle of Ordinary Arc Welding. It Uses Argon Gas to Protect the Metal Welding Material. Through High Current, the Welding Material is Melted into a Liquid on the Welded Substrate to Form a Molten Pool. Itis a Welding Technology in Which the Welding Material Achieves Metallurgical Bonding. After Cooling,a Weld is Formed. Operating Temperature:380℃-420℃ Welding Instructions: 1. Thoroughly Clean the Area You?re About to Weld by Brushing the Base with Stainless Steel Brush Until It Becomes Shiny 2. then Evenly Heat the Area to Be Welded 3. As You Heat, Rub the Rod Vigorously Against the Heated Area Until the Rod Starts Flowing. Quantity:A:30PCS Colour:Silver Material:Aluminum + Magnesium Size:300mm x 1.6mm Package Contents: 30 * Metal Universal Welding Wire Only the
