Inside a soldering iron

Ammonium chloride is used as a flux in preparing metals to be tin coated, galvanized or soldered.

What happens if you touch a soldering iron?

Never touch the element or tip of the soldering iron. They are very hot (about 400�C) and will give you a nasty burn.

What is the heating element in a soldering iron?

Overview of the soldering iron The handle of the iron is thermally and electrically insulated, but the exposed resistant-conductive metal heating element (usually made of copper or nickel) in the tip reaches temperatures high enough to convert metal solder wire into a molten state when subjected to a current.

Why does solder turn black?

When oxidation occurs, the tip becomes covered with a black or brown scale, which will not wet with solder – greatly reducing heat transfer. This is commonly known as “burn-out”. Burned out tips are usually discarded, though they may often be cleaned carefully with a fine abrasive and retinned.

Is flux toxic?

As exposure to rosin-based solder flux fumes may be hazardous to health, their use is subject to the Control of Substances Hazardous to Health Regulations (COSHH) 2002 (as amended). A suitable assessment of the risks to health must be carried out.

What is killed spirits in soldering?

Zinc chloride is often called "killed spirits". It is unequal as a flux when soldering galvanised metals, zinc, brass, copper, lead. It is also used to solder tin that has become tarnished by being exposed to the weather.

Why would they make soldering illegal?

Soldering of connections, particularly the tinning of wires that are to be put into screw fixed receptacles is strongly discouraged. Creep and the possibility that the screw may not remain tight can lead to hot joints, which in turn can melt the solder, leading to a fire.

Is it OK to breathe solder?

Soldering with lead (or other metals used in soldering) can produce dust and fumes that are hazardous. In addition, using flux containing rosin produces solder fumes that, if inhaled, can result in occupational asthma or worsen existing asthmatic conditions; as well as cause eye and upper respiratory tract irritation.

What is solder poisoning?

Solder is used to connect electric wires or other metal parts together. Solder poisoning occurs when someone swallows solder in large amounts. Skin burns can occur if solder touches the skin. This article is for information only. DO NOT use it to treat or manage an actual poison exposure.

Why does my solder just ball up?

Solder balls are caused by gassing and spitting of the flux on the surface of the wave or by solder literally bouncing back from the solder wave. This is caused by excessive back flow in air or too high a drop in nitrogen environments.

What happens if you solder for too long?

A solder bridge occurs when two separate joints melt together as a result of applying excessive solder.

What to do and not to do after soldering?

After soldering, immediately coat the tip in fresh solder to prevent oxidation. Avoid using sandpaper or anything that is too aggressive tools to remove oxidation. This can damage the iron plating that protects the copper underneath, shortening the life of the soldering iron.

Is Vaseline a flux?

Yes, Vaseline works just as well as commercial flux, and you can even buy a generic brand. Petroleum jelly is primarily made from waxes and mineral oils so that it won't corrode your components. Plus, it cleans away the gunk and eliminates metal oxides that could compromise your bond.

Can you get lead poisoning from touching solder?

Lead Exposure from Surface Contamination The primary route of exposure to lead from soldering is ingestion of lead due to surface contamination. Skin contact with lead is, in and of itself, harmless, but lead dust on your hands can result in it being ingested if you don't wash your hands before eating, smoking, etc.

Should I wear a mask while soldering?

Wear safety glasses or goggles no matter what kind of soldering you do: a spatter of 370F molten metal or 300 F boiling flux in the eye will ruin your day, week, etc. Use a fume extractor or noxious organic fume mask to keep the vaporized flux out of your lungs.

What is stronger than soldering?

Advantages of Welding Include: Produces stronger joints than brazing or soldering. Produces welded joints that are better suited for high-temperature applications.

What does a green flame mean when soldering?

Solder paste contains organic binders which burn away during use - this can give a green flame. It's important to heat the metal, not the solder, however, as if you use the flame directly on the paste it will burn and become useless.

Can I use alcohol instead of flux?

Isopropyl alcohol is the #1 solvent used to remove flux off of electronic assemblies. That is because IPA is usually readily available and relatively inexpensive. IPA is not, however, the best cleaner available on the market.

What metal Cannot be soldered?

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

Why do Americans drop the L in solder?

The modern form of the word solder in English is a re-Latinization from the early 15th century. The -l- was dropped on the way to Old French, which was common (for example, pulverem to poudre, collum to cou, calidus to chaud, etc.). Note that the -l- in solder is typically sounded in British English.
