Buying Considerations

Soldering can be too much effort but also fun. It needs a set of tools, including a power box, soldering iron, tips, and other instruments. Unlike hot air-rework, soldering tools are typically smaller and lighter.

But buying a soldering iron can be more problematic than soldering. There are so many options available that it is easy to get confused. That is why we mentioned some factors below that you must consider before purchasing a soldering iron.

Temperature Control

How your soldering iron handles the temperature level is a prime factor. A soldering iron controls and adjusts the temperature of the soldering tips. Apparently, there are three types of temp controls among soldering irons.

The no-regulation type works simply by reaching a standard temperature after setting-up. Then there is the temperature-control that controls the heat using a built-in thermal-control program.

Lastly, the third type is a soldering unit that accepts any thermal tweezer or capacitor. People use them for heavy-duty projects. Whichever one you go for, make sure that the max temperature of it is at least 850-degree F.

Soldering Tips

You got to consider the soldering tips that you will need to attach to the iron. Different shaped and sized tips can be necessary for various work applications. There is the pyramid, conical, tapered, and chisel tips.

A good soldering iron will come with additional soldering tips so that you will not need to look for them elsewhere. Aside from that, look for the durability of them. Great soldering tips must have high temperature surviving capability.

We suggest getting a nickel, copper, or chrome tip, as they are pretty steady and long-lasting.

Power Limit

The soldering iron must pack enough power to get the necessary melting output. While the power wattage can range from 15 to 60, automotive wiring will require 60 watts. Make sure that the power is not more than the requirement as that can damage some components.

Comfortable Grip

It is not an enjoyable experience if your fingers tire out while you are soldering automotive wires. The reason behind that can be the lack of a proper handle. Make sure that your soldering iron has a handle that provides a comfy grip.


Avoid soldering irons that are not from a brand. It is not absolute, but most of them may not survive for a long time. A soldering iron manufactured by a well-known brand provides much reliability and usually is of the best quality.

Final Note

There are many soldering tool bands out there. So, you may still find yourself in an array of options. In that case, you can go for the reviews from the consumers. However, take them with a grain of salt. While some customers are never satisfied, some even review the item without knowing it enough.

Check if your soldering iron has easy temp control and flame height adjustment feature. Price is also a key factor. But for automotive wiring, the best soldering irons can be a bit expensive. Hence, you got to ensure what you are getting is worth the price.
