Why does my solder not stick?

This issue is usually caused by the soldering iron being set to an improper temperature, or the iron itself has a wattage that is too low for the solder size you are using. If you notice your solder isn’t sticking, check your solder material and compare it to the wattage of your soldering iron.

What can I use as a substitute for flux when soldering?

Quote from the video:
Quote from Youtube video: Water-soluble you don't have to clean it with rubbing alcohol or any other type of chemicals to remove rosin flux you can just wipe away the excess. Using a q-tip with warm water.

Is flux necessary for soldering?

Yes, you need flux. Solder wire usually has flux in its core, but most still apply additional flux.

Can you solder copper without flux?

If there really was no flux then you have a “cold” solder joint. The solder may stick in spots but it will not have “wicked” into the “sweat” joint properly and will not completely seal the joint.

Can Vaseline be used as flux?

Does Vaseline or petroleum jelly work? No. The main purpose of flux is to act as a cleaner for the soldering process, so that the solder will properly “wet” the joint. Petroleum jelly is a grease – not good for such purposes.

Why does my solder ball up?

Solder balling can be caused by poor process conditions with gassing from the flux during wave contact or excessive turbulence as the solder flows back into the bath which causes spitting. Solder balls can be ejected from the joint area during soldering due to excessive outgassing of the PCB.

Can you overheat copper pipe when soldering?

If the metal being joined is too cool or too hot, tinning cannot occur. Overheating is a major problem when brazing or soldering copper pipe because the flux will burn (become oxidized), stop working, and become a barrier to tinning.

How do you make homemade solder flux?

Quote from the video:
Quote from Youtube video: 2 teaspoons of tsp. And two teaspoons of products. Absolutely ionized water to help the whole thing dissolve and mix nicely. About a hundred milliliters of deionized. Water.

What’s the best solder for copper?

Types of Solder

Buy lead-free solder that’s designed for copper water pipes; you’ll find it in the plumbing section of the store. Solder with lead is still available, but the lead can leach into your water supply, so don’t use it.

Is all flux the same?

There are three different categories of fluxes used to solder electronics according to IPC J-STD-004B, Rosin and Rosin Substitutes, Water Soluble, and No-Clean. After the soldering process, the rosin and water-soluble fluxes need to be chemically cleaned to remove any excess flux residue that remains.

Is soldering paste the same as flux?

Solder paste flux is different than liquid flux in both physical form and activity level. Solder paste flux typically contains 60-80% by weight active ingredients, compared with liquid flux’s 2-25%. By weight, a mixed solder paste commonly consists of 90% metal.

Which flux is used for copper soldering?

We recommend tinning flux. It contains a bit of powdered metal alloy that is similar to solder. The alloy melts and coats the inside of the joint and helps ensure a solder joint that’s completely filled and leakproof.

What type of flux is typically used for electrical soldering?


Rosin (type R) Flux

The most basic soldering flux, one that has been used for over a thousand years, is the natural rosin derived from pine tar resin. Pine tar resin is dissolved in solvent and then distilled to yield the clear, water-white rosin used in soldering flux.

Which flux is used for gold soldering?

Batterns Self-Pickling Flux is used for hard soldering (solder that melts at a high temperature) of gold, silver, and platinum. It can be diluted with distilled water if it’s too thick. Don’t be fooled by the name. You’ll still need to pickle the item before soldering.

Can you solder 24k gold?

Chain soldering: 22k and 24k chains are uncommon, but like all chains they are prone to snapping and breaking with enough force. The jeweler simply solders the broken pieces back together in order to reconnect the chain. However, patterned chains such as rope chains may have a visible area of sizing.

Can you solder gold with a butane torch?

Select a precision torch for melting the solder.

A small oxy-acetylene gas torch is a good choice, but butane or other high-temperature torches will work as well.
