What can be used as soldering paste?
Petroleum Jelly. Petroleum jelly works just as well as a store-bought flux. It will clear your metal surfaces of any oxides and will melt away with the heat. Because of this, it is commonly used by many electronics enthusiasts.

Is flux and soldering paste the same?
While the main use of solder paste flux is in the creation of solder paste, it is also sold directly as a gel or tacky flux. Solder paste flux can also act as a temporary adhesive. Once mixed, solder paste is most commonly used in a stencil-printing process.
Is soldering paste necessary?
For a good soldered joint, the proper amount of solder paste must be used. Too much paste may result in a short circuit; too little may result in poor electrical connection or physical strength.
Why does my solder not stick?
A classic reason solder won’t stick to something is because you’re not getting it hot enough. My interns come to me with this problem all the time. Make sure the tip of the iron is nice and shiny. Touch some solder on it, and it should melt almost instantly.
Can you use a paperclip as solder?
Apparently paperclips are also made of galvanised steel as a rule, so there may be a connection here. Other metals such as aluminium or regular steel can be soldered, but require special solder and flux and may need stronger equipment.
What is the purpose of solder paste?
Solder paste is a combination of a powder made up of metal solder particles and sticky flux that has the consistency of putty. The flux not only does its usual job of cleaning the soldering surfaces of impurities and oxidation, but it also provides a temporary adhesive that holds the surface mount components in place.
How long does solder paste last?
What is the shelf life of solder paste? At a minimum, nine months for SolderPlus dispense paste, twelve months for PrintPlus print paste and twelve months for FluxPlus paste flux when stored as recommended. Warmer conditions will reduce shelf life and/or cause flux separation with solder paste.
Do you need flux with solder paste?
What chemicals are in soldering flux?
Common fluxes are ammonium chloride or resin acids (contained in rosin) for soldering copper and tin; hydrochloric acid and zinc chloride for soldering galvanized iron (and other zinc surfaces); and borax for brazing, braze-welding ferrous metals, and forge welding.
What metal Cannot be soldered?
Of metals
| Solderability | Metal |
|---|---|
| Fair | Carbon steel Low alloy steel Zinc Nickel |
| Poor | Aluminium Aluminium bronze |
| Difficult | High alloy steel Stainless steels |
| Very Difficult | Cast iron Chromium Titanium Tantalum Magnesium |
What material does solder not stick to?
Solder simply will not adhere to dirty or oxidized metal surfaces. Clean any flat surfaces which are to be soldered with steel wool, a file, emery cloth, etc. It’s important to take time to clean the surface thoroughly. Scrape any wire to be soldered with the back of a knife or any flat piece of metal (Fig.
Where can I buy solder and soldering supplies?

Which is easier to use, soldering or brazing?
Brazing and soldering don’t bond metals as well as welding does, but they can still create a very strong joint. These methods can join dissimilar materials together and are known to be much easier to do than traditional welding practices.
What do you need to know about welding at Lowes?
Welding is the process of melting metal pieces in order to join them together. Welders for sale at Lowe’s come in several styles and have different uses. We also carry all sorts of welding supplies, including essential welding tools and safety gear, like welding helmets and welding gloves.
Can a stick welding machine be used for soldering?
A stick welding machine is versatile and affordable but can only be used on metals that are at least 18 millimeters thick. Brazing and soldering don’t bond metals as well as welding does, but they can still create a very strong joint.
