10 best core soldering
Core soldering is a common technique used in soldering, which is the process of joining two or more pieces of metal together by melting a filler metal, known as solder, and allowing it to flow into the joint. This process is widely used in various industries, including electronics, plumbing, automotive repair, and jewelry making. Core soldering typically refers to solder that comes with a core of flux inside it, and it offers several advantages:
Flux Core: Core solder contains a core of flux, which is a chemical compound that helps clean the metal surfaces being soldered and promotes the flow of solder. The flux core eliminates the need to apply flux separately, making the soldering process more convenient and efficient.
Convenience: Core solder is available in various diameters and types to suit different applications. It comes in a wire or rod form, making it easy to handle and apply to the joint.
Different Alloys: Core solder is available in various solder alloy compositions, such as lead-based and lead-free.The choice of alloy depends on the specific requirements of the soldering task and environmental considerations.
Reduced Oxidation: The flux in the core helps prevent oxidation of the metal surfaces being soldered. Oxidation can hinder the soldering process and result in weak joints. Core solder ensures a cleaner soldering process and a stronger bond.
Versatility: Core solder can be used for a wide range of applications, including electrical and electronic soldering (e.g., soldering wires and components on circuit boards), plumbing (e.g., joining copper pipes), and general metalwork (e.g., jewelry making and stained glass work).
Soldering Iron or Torch: Core soldering can be done using various heat sources, such as soldering irons, soldering guns, or torches, depending on the specific task and materials involved.
Safety Considerations: When working with core solder, especially lead-based solder, it's essential to follow safety guidelines to minimize exposure to harmful fumes and ensure proper ventilation in the workspace.
Quality Joints: Proper technique and the use of quality core solder can result in strong, durable joints that provide electrical conductivity (in the case of electronics) or fluid-tight seals (in plumbing applications).
In summary, core soldering is a widely used technique in soldering that involves solder with a flux core. It simplifies the soldering process, enhances the quality of joints, and finds applications in various industries where metal joining is required. The choice of core solder type and alloy composition should be based on the specific needs of the soldering project.

User questions & answers
| Question: | Does this work okay for soldering brass |
| Answer: | It is easy. Start testing the temperature with the as soon as the iron starts warming. If you heat the tip until it is discolored before applying solder it may be difficult. |
| Question: | How do you solder. Do you put the solder on the iron than run over the wire or it should just melt on the wire without the iron melting the solder |
| Answer: | I would not use it, the problem is if you leave it plugged in for more than 45 min. The heat transfers to the handle and it starts to melt. They used to make the handle out of wood which would allow the unit to be plugged in for extended use. |
| Question: | Which size (mm) do I choose for cellphone, TV, or smallhousehold appliances etc |
| Answer: | Yes |
| Question: | What kind of soldiers can work for bikes |
| Answer: | You would use the MT series tips. |

User questions & answers
| Question: | Does this flux need to be cleaned from the pcb after through hole soldering. if so what should i use |
| Answer: | It doesn't have to. But if u want to clean it up a lil use some isprophnal |
| Question: | I am going to be soldering for sculpture. Would i need to purchase a seperate container of rosin since this wire contains rosin |
| Answer: | My experience is only with soldering electronic components. And I’ve never needed anything else. Wouldn’t think you would with sculpturing. The videos I’ve seen with artists who do stain glass work don’t use it as well. |
| Question: | how long is the reel of solder |
| Answer: | Measured about 13meters per reel. |
| Question: | What is the 'reactivity' of the flux? r(weak),rma(mildly reactive) & ra(highly reactive) ? ; helps determine cleaning requirements |
| Answer: | Based on my own experience using this, I would rate the 'reactivity' as mildly reactive. Hope this information helps. |
