Features:1. Welding effect is good: its welding effect is full, smooth With the help of internal powder. With low melting point, good fluidity, hardness and toughness, good sealing. Do not have to use other flux powder2. Direct use: do need any flux poweder, open package that is used Very convenient Easy to weld.3. Welding: firsst use sandpaper to polish brass and aluminum tube welding parts must to clean metal surface's paint, oxide, oil, etc, moving the guns to be heated evenly welding parts, and then continue to use the electrode to be welded When the temperature rises to 360 degrees, the copper and aluminum welding rod to melt and evenly into the joint, Remove the torch after the weld is full , waiting cooling is OK. No further treatment after cooling, flux residue is visible but not corrosive, non-hygroscopic and firmly attached.Suitable for:1. Transformer and reactors' aluminum and copper joints' copper and aluminum foil's welding2. Refrigerator and air conditioning's condenser / evaporator's aluminum pipe and brass's welding;3. Radiators, motors, batteries, household appliances and other products' copper and aluminum wire's welding.Specifications:Products name: Copper Aluminum Flux Cored WireDiameter: 2.00mmLength: 1/2/3/5mPackage List:1 x Copper Aluminum Flux Cored Wire
