Types of Wire Stripping Tools

When it comes to wire stripping tools, there are three main types that I would like to discuss. These include manual wire strippers, automatic wire strippers, and self-adjusting wire strippers. Each type has its own advantages and disadvantages, so it is essential to understand the differences to select the best option for your specific needs.

Manual Wire Strippers

Manual wire strippers are the most basic and affordable option. They require me to use my hand strength to remove the insulation from the wire. These tools typically have various sizes of notches for different wire gauges. I need to choose the correct size of the notch, place the wire in it, and firmly squeeze the handle to cut through the insulation. After that, I can pull the insulation off to expose the conductive wire. Manual wire strippers are inexpensive and portable, making them a popular choice for occasional use and simple tasks. However, they might take more time and effort to use than other options, especially with larger wire gauges.

Automatic Wire Strippers

Automatic wire strippers provide a more comfortable and faster way to strip wires. This is the option I use most often, and I’ve written a post about my favorite pair here. With this type of tool, I can cut and strip wires in one motion. They often have an adjustable stopper to control the strip length, ensuring consistent results. To use the automatic wire stripper, all I have to do is insert the wire into the appropriate gauge slot and then squeeze the handle firmly. The device will grip, cut, and strip the wire simultaneously. The key advantages of using an automatic wire stripper are its speed and precision. However, they can be more expensive than manual strippers, and they might not be as portable due to their larger size.

Self-Adjusting Wire Strippers

Self-adjusting wire strippers are similar to the automatic ones, but they come with a unique feature – the ability to adjust to the wire size automatically. To use a self-adjusting wire stripper, I simply insert the wire into the tool and squeeze the handle. The tool then adjusts to the wire’s size and strips off the insulation without any damage to the conductor. These wire strippers save me time and effort since I don’t have to worry about selecting the correct gauge size. Self-adjusting wire strippers are perfect for projects involving multiple wire sizes, as they provide a quick and hassle-free way to strip wires. However, these tools can be more expensive than manual or automatic wire strippers, so they might not be the best choice for those on a budget.

Understanding Wire Gauges

When working with wires, it’s crucial to understand wire gauges, which are the standard method of measuring a wire’s diameter. As a professional, I always pay attention to wire gauges as they indicate the wire’s current-carrying capacity and resistance to electrical flow.

Wire gauges are measured by the American Wire Gauge (AWG) system, which assigns a number to the wire based on its diameter. Interestingly, the higher the gauge number, the thinner the wire. For instance, a 20-gauge wire is thinner than a 10-gauge wire.

Wire gauges impact the performance and safety of electrical installations. Thicker wires are capable of handling larger current loads and have less resistance, which means they generate less heat. For reference, here’s a table of common wire gauges and their diameters:

AWGDiameter (inches)

A wire stripping tool’s functionality is directly linked to understanding wire gauges. When using a wire stripper, it’s vital to choose the correct notch that corresponds to the wire gauge being used. By doing so, you can avoid damaging the wire conductor or insulation, ensuring a reliable and safe connection.

Proper Techniques for Wire Stripping

Manual Stripping Techniques

When I work with manual wire stripping tools, I make sure to select the right tool, such as an adjustable wire stripper or a simple wire cutter. To ensure a clean and precise cut, I match the gauge markings on the stripper with the wire size. I then grip the wire firmly, without applying too much pressure to avoid damaging the inner conductors. Afterward, I rotate the tool around the wire to create a clean cut, ensuring I don’t cut too deep. Finally, I gently pull away the insulation, revealing the properly stripped wire.

For wires with multiple layers, I repeat this process for each layer. Occasionally, I use a wire stripper with a built-in cutting blade, which can perform a quick and precise cut without rotating the tool around the wire. This type of stripper is particularly useful for multi-stranded wires or those with thin insulation.

Automatic Stripping Techniques

When using an automatic wire stripper, I first set the required stripping length and wire gauge based on the manufacturer’s guidelines. Once it’s adjusted, I insert the wire into the tool and press the lever or button, which automatically strips and removes the insulation. Automatic strippers can be a significant time-saver when handling large volumes of wires, ensuring consistent and efficient stripping.

Some automatic wire strippers are equipped with an adjustable stopper to control the stripping length. Pay attention to the stopper position to make sure it’s set correctly to avoid irregular wire stripping. Additionally, I make sure the blades are clean and sharp, as dull or dirty blades can damage the wire and render it unusable.

By following these manual and automatic wire stripping techniques, I consistently achieve clean and accurate stripping without damaging the inner conductors or compromising the integrity of the wiring. Proper wire stripping is essential when it comes to installing or repairing electrical wiring, ensuring safe and reliable connections.
