Is 40 watts good for a soldering iron?
For most guitar repairs, a 30-40 watt soldering iron will suffice. However, if you're working on something larger or are using a thicker solder, you may need a higher wattage soldering iron. A soldering iron concentrates heat at the tip and connects two metal pieces or metal wires to “solder” them.
The wattage rating should be between 20 and 50 watts.
A higher-wattage soldering iron can maintain a stable temperature longer while you're soldering a connection and can reheat itself faster in between.
Perfect for general repairs, this 40-watt soldering iron produces temperatures up to 600-640ºF.
Your typical soldering iron is rated between fifteen and twenty-five watts. Higher wattage soldering iron have more power, thus making them better suited for heavy-duty projects than their low-wattage counterparts.
Wattage Ratings
If you need a soldering iron for basic soldering operations, 40 to 60 watts should be enough. But if you're working on heavy-duty soldering projects, aim for 70 to 100 watts.
A 30 watt 'simple soldering iron' is okay for modest electronics. Soldering ordinary through hole electronic components and thin (e.g. mm) wire, even the thin metal legs on DC power plugs and sockets, should be fine.
A 30-40 watt fixed-temperature iron will be on the hot side for electronics work. It will melt solder very quickly and make it really easy to heat up large component leads quickly, such as those on connectors.
Typically 40W or 60W. The reason for the temperature control is that a high wattage iron can get damagingly hot - can damage the board that you are soldering to. But a low wattage iron temperature can fall quickly and lead to dry joints.
An unregulated 60 watt iron is good for for very high speed work, especially on large connections. Even a 45 watt iron can be too hot for PC board work, but with a little care it makes clean connections quickly. 30 is actually quite useful and relatively maintenance free if good enough quality.
The higher the wattage of a light bulb, the more heat it will produce. A 60-watt bulb can get up to 200 degrees Fahrenheit on the bulb's glass surface. A 40-watt bulb can reach temperatures over 100 degrees Fahrenheit.
What to look for when buying a soldering iron?
Wattage: you should pick up a soldering iron with at least 30 watts of power. Soldering irons with low wattage take longer to heat up and are not consistent holding the temperature. Tip compatibility: the iron's tips should be replaceable, and the iron should be compatible with a wide variety of tips.
This iron is an adjustable 50W iron with a temperature range from 200-500°C, For most lead free soldering, try 400°C. For lead-based solder, 350°C will do.
For electrical and electronics work, a low-power iron, a power rating between 15 and 35 watts, is used. Higher ratings are available, but do not run at higher temperature; instead there is more heat available for making soldered connections to things with large thermal capacity, for example, a metal chassis.
60/40 solder is made of 60% tin and 40% lead. It has a melting point of around 190°C, depending on the exact composition. Iron tip temperatures of at least 300°C are recommended. It is also very soft, meaning that cracks do not form so readily if the joint moves during cooling.
Sure, solder stations may go up to 900°F, but 750°F is the highest you need to go for a lead-free wire. The extra heat can also unnecessarily stress components, increasing the chances of PCB failure later.
Professional quality 35 watt, 120VAC Weller soldering iron with an operating tip temperature of 850° F.
25W should be enough for simple stuff like soldering two wires together. In fact, after 5-10 minutes the problem will be the tip will get too hot and therefore oxidize excessively and overheat things it touches. If it's not doing that then it's most likely broken.
Product Information. Perfect for integrated circuit work and minor repairs, this 25-watt soldering iron produces temperatures up to 600-640ºF.
You can use anything that is able to heat a piece of metal up to the melting point of your solder (between 400°F / 200°C and 700°F / 370°C). Butane lighters work the best. But you can also use candles, oil lamps, alcohol burners, or even open camp fires.
A hair dryer would not be able to produce enough heat to melt the solder and shrink the tubing. We recommend using a heat gun with these Wirefy heat shrink solder & seal connectors.
How many watts does it take to solder 12 gauge wire?
Get a good tip, keep it wet and use good skill, and you easily could solder 12awg with a 30W iron.
An unregulated 60 watt iron is good for for very high speed work, especially on large connections. Even a 45 watt iron can be too hot for PC board work, but with a little care it makes clean connections quickly.

Low temperature solders have melting points ranging from 117°F (47°C) to 320°F (160°C). These solder alloys contain Tin blended with a variety of metals such as Bismuth, Indium, Cadmium, etc.
If using a 60/40% tin lead wire soldering, there will be a varying melting temperature range. It will begin to melt at 361.4°F and become a full liquid at 375.8°F. Tin lead wire solder is ideal for applications where there are delicate temperature requirements for soldering.
