Solder how many watts




















Soldering Tools for Home Projects. Soldering Vacuum Tubes. Do soldering irons wear out? Soldering Iron tips do not last forever. Eventually they wear out. Common signs that the tip needs replacing are: a hollow forming in the end of the tip, cleaning and re-tinning has no effect, or needs frequent repeating.

What size solder should I use? Best Size Solder For basic electronics work, a solder wire approximately 0. However, solder diameter is determined by the gauge number. Your basic average student will be working with through-hole PDIP packages, hence gauges that work well are 18, 20, and What is a good soldering temperature?

Although tip temperature is not the key element in soldering you should always start at the lowest temperature possible. What should I look for when buying a soldering iron? Here are some things to look for when purchasing a soldering iron: The wattage rating should be between 20 and 50 watts. The higher the power, the better the station is able to maintain the temperature of the tip. At a higher soldering temperature and when soldering well conductive and large parts of metal, more power will be needed.

So only when there is a good contact surface between the tip and the application the high power of a soldering station is useful. This applies to all soldering irons in all price ranges and of all brands.

Suppose you want to solder a thick copper cable with a 0. However, if you use a 5mm tip with sufficient soldering tin, then the soldering station will have to work much harder to maintain the temperature and the high power e.

Maha Powerex chargers are widely used by professionals. Also, most solder nowadays come with a rosin core which does the job of flux helping breaking down oxides. Turn on the soldering iron and set temperature above the melting point of your solder. Potentiometer VR1 is used for setting the temperature of the soldering iron. Semiconductor components such as diodes and transistors are easily damaged by the high temperatures of soldering, so care must be taken to protect these components during the soldering process.

One way to do this is to use a heat sink to draw heat away from the component without cooling the connection point too much. Rosin core flux solder has the flux embedded into the core of the solder and should not need any additional flux added, although it would not hurt. Be sure NOT to use acid flux on electronic or electrical connections. Acid flux is used in plumbing. The primary advantage of this solder is not the lower melting point, but its eutectic property.

If a joint is moved during this stage, it can result in what is called a cold solder joint. It has its melting point at C, and the 0. The main types of solder are lead and lead-free. You can use both for electronics, but it can be easier to work with lead-based solder. Lead-based solder wire, 1. Lead-Free Solder Rosin Core. People can get lead poisoning from soldering if the solder used contains lead.

Dust and fumes can enter the body through inhalation or ingestion. Lead solder is still used in electronics. It could even save you real money since you have less risk of damaging PCB's. I have that exact iron Hakko clone and it works great. It's one of the best deals out there for soldering irons in my opinion. The ones we use at work are Metcal soldering irons. They are more expensive than Wellers, but they're in a different league and are much better for small stuff. A low-end soldering iron may well work for you; I'm just trying to show you alternatives.

I would recommend a temperature controlled soldering iron. That way you will know what temperature it is at so it won't get to hot and potentially damage what you are working on. And they come in a variety of makes and models so you can find one that is in your price range. It's a digital temperature controlled station that has preset, adjustment and sleep modes, as well as a low temperature alarm.

It also heats up fast and has a fast recovery time. From what I have read Hakko is a good reliable brand and people like their stations. Plus tips are easy to find, just in case you need to replace a few as you begin to learn.

Weller and Metcal also make temperature controlled stations but they are more expensive. I guess it all boils down to what you feel comfortable spending. If you plan on keeping it a while and using it a lot it may be worth spending the extra money. Sign up to join this community. The best answers are voted up and rise to the top.
