Simple Welding Rods_ Solution Welding Flux_cored Rods_ No Flux Required_ Easy Solution Welding Rods 2mmX50cm B_30 PCS

Solution welding Flux-Cored Rods,  no flux required, super low melting point stonger than parent metal excellent corrosion resistance. Specification: Quantity: 10/30/50 PCS Material: Aluminum Color: Silver Melting Point: 647?~658? Diameter: 2mm / 0.08" Length: 500mm / 19.7" Item Wight: Approx. 5g (One Aluminum Welding Wire) How to Use: Step 1: Clean and polishe the physical surface. Step 2: Heat the surface of the base material, until the temperature of the wire to the operating temperature of 380?~400?, so you can rely on the parent metal heat transfer welding wire to form welds, should not use the flame to burn wire, When the surface temperature of the base metal is sufficient, the wire can flow well and penetrate into the metal capillary. Step 3: When repairing thin aluminum, as long as the aluminum base metal heated to the appropriate working temperature, and then use the wire back and forth friction melting to form a weld, only with a metal brush melt welding wire to weld at the weld. Step 4: Use propane gas to weld s mall object, use industrial gas or induction heating device to heat and weld big object, natural slow cooling after welding.  NOTE: 1. The surface of the base metal must be clean. 2. The base metal temperature to reach 400 degrees, including the process of welding the base metal temperature should be maintained at 400?, and the temperature can be high or low.
