Specifications: It is suitable for welding of copper and copper pipe joints in refrigeration systems of air conditioners, freezers and refrigerators. It features with low melting point and good fluidity that makes it very reliable and efficient. Because of its simple and convenient operation, it will not waste your time and energy. Made of copper material, it is very durable to use. There are six specifications for you to choose. Featuring the exquisite and professional workmanship, it has a strong caulking. It has a wide range of applications, making it will be used in a variety of welding scenarios. Notes: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Phosphorus copper electrodes do not require flux for welding red copper pipes. Phosphorus is a reducing agent that can reduce cuprous oxide and generate phosphorous oxides floating on the surface of the weld. Phosphorus copper electrodes have good fluidity and self-soldering effect. Flux is used for other silver-copper electrodes. Package Includes: 10 x Phosphor Copper Welding Rods
