Soldering Coppers

We offer a variety of soldering coppers for structural soldering. Soldering coppers are typically heated with natural gas, propane, or a cast iron furnace. They are used to supply heat to melt solder, so it can flow between two surfaces. The larger the soldering copper, the larger the joint area it can heat, and the more heat it can bring to your process. This increases the time you have to work before the soldering copper needs to be reheated. However, the larger the soldering copper, the more open space is required to reach your joint and the more arm and hand strength it takes to precisely control the copper during soldering. The optional heat-proof wooden handle provides a comfortable grip and fits all of our soldering coppers.

Common Applications for Copper Solders Include: 

• Adding or repairing the handle on a stainless steel bucket

• Manufacture and repair of stainless steel tanks, sinks, and trays

• Joining parts of steel and stainless steel knives and appliances

• Filling joints in copper and stainless steel gutters and roofs

For production line operations, they are usually purchased in pairs to allow the user to heat one soldering copper, while using the other. Smaller projects, however, can utilize one soldering copper on its own. We offer 1 lb., 2 lb., and 3 lb. soldering coppers with both chisel and pointed heads. 

Chisel Tip vs. Pointed Tip:

Chisel tips feature a broad tip that helps deliver even heat to the component parts over a larger surface area. They are predominantly used for soldering lap joints between two sheets of copper or stainless steel. 

Pointed tips are typically used for precision soldering and general soldering of smaller and more complex joint geometries. The pointed tip helps deliver heat to smaller areas in butt joints and folded corners. 

Choosing the Right Size Soldering Copper

In general, the larger the variety of joint geometries you need to process, the smaller the soldering copper should be. For example, if you have a wide variation in tank sizes you need to process, but all the joints are lap joints, use the smallest chisel point that will fit in the smallest tank. If you are processing a larger corner joint with easy access, use the largest pointed tip that will fit your joint and your ability. You need to get consistent heat to both parts at the same time to get the solder to stick to both parts.
