Hover the sucker over this area until you melt the solder. The breadth of the product line includes fluxed and un-fluxed rectangles, washers, sleeves, and custom shapes for specific applications. Silver Solder refers to when you’re using solder that’s around 45 percent silver or higher. In order for solder to do its job, the layer of oxides on the metal surfaces you're soldering must be removed. It’s useful when you’re making joints with steel, like when connecting copper lines to steel, or connecting steel to steel. This will make it easier to apply the solder to the hot fitting, particularly on the backside of the pipe. For filling deep holes, apply LIQUID METAL FILLER. Skipping this step may result in an improperly brazed joint.Step 2 is the actual b… In soldering the filler material becomes liquid, coats the pieces it is brought into contact with, and is then allowed to cool. You may purchase this as a container of pre-cut chips, or purchase it in sheet or wire form and cut off 1/8 inch (3mm) chips with wire cutters. The solder follows the flux, as if the flux were clearing a path for the solder and telling it where it to go. If desired, use a wet putty knife or spatula to smooth out the repair. Once it is, release the button and suck the solder away. Pierce the seal in the head of the tube. Immediately after cleaning the metal, apply the flux along the area to be joined using a rod of solder or a small metal tool. You won’t use this type of solder too often. As the solder cools it hardens, and the two materials are joined. Soldering is a process that creates electrical, mechanical, or thermal bonds using heat, filler material, and flux. LIQUID METAL FILLER will dry in 3 to 4 hours. For a solder sucker, you press the plunger-device down and then heat the area with your iron. There are 3 easy steps to getting this accomplished.The first step is to prepare the joint. A good flux, like #135, removes the oxides and sets the stage for soldering. Soldering is a quick way to join many types of materials, from copper pipe to stained glass. This will prevent further oxide from forming and draw the solder along the length of the join. When you are satisfied, remove the braid. Apply LIQUID METAL FILLER straight from the tube. … If soldering wires, dip them in the liquid flux instead. Activate the pump to suck the liquid solder away from the electrical contact before it cools and re-solidifies. For example, you might use this on service valves that bolt on to a compressor. Now use a propane torch to heat the joint. Although the practice of soldering has been around for thousands of years, current soldering processes are often state-of-the-art and require the best materials for consistent, reliable, and void-free solder joints. You’ll probably have to repeat the above step two or three times to get all of the old solder away from the electrical contact completely. ALPHA ® Solder Preforms are used in industries ranging from PCB Assembly, stand-alone industrial applications, and high-end power semiconductor packages. For best results, roughen the surface slightly with sandpaper. Silver solder is an alloy formed from silver and other metals, designed to join with silver but melt at a lower temperature. Purchase silver solder. How to CORRECTLY Braze (SILVER SOLDER) a Copper Pipe: So, today I’ll be explaining to you how to correctly braze a copper joint. The heat transfers through and melts the solder, which is then absorbed into the braid. Before you start to solder anything, unroll about 12 inches of solder off the roll and then make a right angle bend about three inches from the tip.
