Plastic covers on cables are important as they protect the connection of the metal end to the wires. However, sometimes they need to be removed. One way to do this is to carefully slice the plastic cover from the easy-on end down the middle, leaving it still attached at the wire end. This allows the plastic cover to be slipped down the wire and easily slipped back up and reattached. Alternatively, you can use a wire wrap tool to cut through the plastic insulation and strip it off the metal. If you are stripping wires to connect electronics, be careful not to accidentally remove too much insulation.

What You'll Learn
Use a wire wrap tool to cut through the plastic insulation
To cut through the plastic insulation on a cable, one of the tools you can use is a wire wrap tool. This tool is designed to strip the insulation off of wires, and it can be used to cut through the plastic insulation without damaging the wire itself.
- Start by identifying the type of wire you are working with. It is important to know the wire's gauge, which is the thickness of the wire. You can find this information on the insulation of the wire, labelled as an American Wire Gauge (AWG) number.
- Adjust the wire wrap tool according to the wire's gauge. Most wire wrap tools have adjustable settings to accommodate different wire sizes.
- Firmly hold the wire with one hand, ensuring that you have a good grip on it.
- Insert the wire into the wire wrap tool's slot or blades. The tool should have a designated area where the wire needs to be placed.
- With the other hand, hold the wire wrap tool. Gently squeeze the handles of the tool together to start cutting through the plastic insulation.
- Continue to apply pressure and slowly pull the wire through the tool. The blades of the wire wrap tool will cut through the plastic insulation as the wire passes through the tool.
- If you are having trouble stripping the insulation, try twisting the wire wrap tool around the wire before pulling it through. This technique can help the blades catch and cut through the insulation more effectively.
- Once you have cut through the desired length of insulation, release the wire from the tool.
- Dispose of the plastic insulation appropriately.
It is important to note that you should always exercise caution when using any sharp tools, like wire wrap tools, to avoid accidental injury. Additionally, ensure that you are working in a well-lit area with a clear workspace to prevent any mishaps.

Twist the wire wrap tool for better results
To achieve better results when using a wire wrap tool, it is important to follow a few key steps and tips. Here are some detailed instructions and considerations to keep in mind:
Firstly, insert the pre-stripped wire into the wire slot of the wrapping bit. Ensure that the wire is securely anchored in the notch of the wrapping sleeve. This step is crucial for maintaining proper tension and avoiding any slippage during the wrapping process.
Next, insert the terminal into the centre hole of the wrapping bit. This step ensures that the wire will be wrapped around the terminal securely. Once the terminal is in place, you can activate the wire wrapping tool.
When activating the tool, be mindful of the pressure you apply. Holding a wrap gun with too little pressure can result in spaces between the coils, while pulling the trigger too hard may cause the wire to break inside the gun barrel. It is important to find the right balance to ensure a consistent and tight wrap.
Additionally, be cautious when applying force while turning the tool. Excessive force can lead to an overwrap, where the wire slips over the preceding turn. "Backforce" features on electric wrap guns are designed to prevent overwrapping, so it is important to consider the tool's capabilities and adjust your technique accordingly.
For a more permanent and secure connection, consider adding some solder between the wire and the pin after wrapping. This extra step will enhance the durability of your work.
Finally, practice is key to achieving quality connections. Insufficient turns or improper feeding of the wire into the wire slot can result in subpar results. Take the time to familiarize yourself with the tool and the wrapping process to refine your technique and improve your overall results.

Use a utility knife to cut through the insulation
When using a utility knife to cut through insulation, it is important to choose the right type of knife and to prepare your work area to ensure a clean cut.
First, select a suitable utility knife. While any sharp knife can be used, some are better suited to the task than others. A utility knife with a solid, fixed straight blade is ideal for cutting insulation. Alternatively, a scalloped bread knife or a serrated bread knife can also be effective. If using a bread knife, it is important to note that the knife does not need to be sharp. For thicker insulation, a pipe knife or an electric meat carving knife with two serrated blades can be used.
Before cutting, prepare your work area to ensure a clean and precise cut. Place a piece of scrap plywood under the insulation to protect the surface underneath. Then, place a piece of wood or a drywall T-square on top of the insulation to compress it and provide a straight edge to cut against. This will make the cutting process easier and help to ensure a straight cut.
When cutting the insulation, use a gentle sawing motion, especially if using a serrated blade. For thicker insulation, it may be necessary to make multiple passes with the knife. If the insulation is particularly thick, consider compressing it further or using a knife with a longer blade, such as a chef's knife, to make the cutting process easier.
After cutting, be sure to clean the knife to remove any residue from the insulation. For example, if cutting against concrete, the knife may need to be cleaned with mineral spirits to remove tar residue. Always handle the knife with care and wear appropriate protective gear, such as gloves and eye protection, to prevent injuries.

Adjust the length limiter to remove the plastic cover
If you need to remove the plastic cover from a cable, there are a few methods you can try. Firstly, check if the plastic cover can be easily slipped off. If it is stuck, gently try to tug it down. You can also try to tumble the cable left and right and pull outwards at the same time. If it is still stuck, it might be heat warped, in which case you can try gently widdling and pulling the cover with a pair of pliers.
If you want to keep the plastic cover intact, you can carefully slice the cover from the easy-on end down the middle, leaving it still attached at the wire end. This will allow you to slip the cover down the wire and easily adjust its length. Once you are done, you can slip the cover back up and reattach it using super glue or another adhesive.
Remember that the plastic cover is there to protect the connection of the metal end to the wires and to prevent shorting the button, so it is generally a good idea to keep it on. However, if you need to remove it temporarily to fit the cable through a tight space, the above methods should help. Just be sure to put the cover back on once you are done for continued protection.
