4 Common Wire Stripping Mistakes and How to Avoid Them

Wire strippers can be frustrating when wires slip or refuse to grip properly. While equipment issues sometimes cause these problems, your technique and attention to detail often make the difference. This guide focuses on the CREWORKS Automatic Wire Stripping Machine, but many principles apply to similar wire strippers. You might strip just a few wires or process hundreds of pounds of copper monthly. Either way, learning to avoid basic mistakes will help you work faster and make your wire strippers last longer.

Quick Summary of Critical Mistakes: 

✗ Using wrong feed hole size for wire diameter 

✗ Incorrect safety guard height adjustment 

✗ Feeding curled instead of straight wire 

✗ Insufficient component tightening

1. Incorrect Wire Diameter and Feed Hole Matching

One of the most frequent mistakes people make is using the wrong feed hole size for their wire diameter. This mismatch often leads to wire shifting and inconsistent stripping results.

Expert Tip: Always measure your wire diameter including insulation before selecting a feed hole.

Here's the correct feed hole selection guide:

How to Feed Wire Into Your Stripper

1) Standard Method (For wires 0.06–0.5 in. / 1.5–13 mm)

Your wire stripper comes with a safety guard already installed - here's how to use it properly:

Feed your wire through one of the pre-cut holes that matches your wire size. Loosen both locking bolts, then slide the guard up or down until your wire sits perfectly on the roller joint. Once positioned, tighten both bolts firmly.

In case you are having trouble getting the wire lined up right, try moving the bolts to the lower holes for better positioning.

Pro Tip: If you're having alignment issues, you can unscrew the bolts and move them to the lower bolt holes for better positioning.

2) For Larger Wires (For wires 0.5–0.98 in. / 13–25 mm)

If you are working with bigger wires, you'll need to swap out the standard guard for the larger one:

Remove the standard guard by taking out both bolts completely. Put the new 25mm guard in its place and insert your wire. Adjust the guard's height until the wire rests correctly on the roller, then tighten those bolts completely. Don't skip the final tightening - loose bolts will give you messy, uneven strips.

Important: Never skip the final tightening step - loose bolts can lead to inconsistent stripping results.

3) For Tricky Wires (Variable Sizes or Curled)

Sometimes you need more flexibility - that's where the wire strippers’ adjustable plates come in handy:

Take out both bolts and stack the outer plate over the inner one. Place them against your stripper, lining up the side slots with the bolt holes. Put the bolts in loosely, feed your wire through, then slide the outer plate until you've got the right-sized opening. Tighten everything down firmly.

This setup works great when you're:

• Switching between different wire sizes often
• Working with curled wire
• Dealing with non-standard wire sizes
• Need quick adjustments between jobs

Stay Safe! 

Before you start stripping:

• Check that emergency stop button
• Following OSHA guidelines, always wear appropriate PPE including safety glasses and work gloves.
• Keep your hands clear of the cutting area
• Practice on some scrap wire when trying a new size

2. Improper Guard Height Adjustment

If your wire keeps shifting around, the guard height might be the problem. Getting it right makes a huge difference in your stripping results.

Here's how to set it perfectly: 

1. Loosen both locking bolts and move the guard until your wire sits centered right on the roller joint. 
2. Take an extra moment to check that everything's lined up properly, then tighten those bolts completely. 
3. Never run your machine without the guard properly locked down.

3. Using Curled or Improperly Prepared Wire

The Copper Development Association emphasizes that proper wire preparation significantly impacts both processing efficiency and final material value. While it's tempting to just grab your wire and start stripping, taking a moment to straighten it first will save you headaches later. The machine works best with straight wire, and here's why:

Curled wire can slip off the cutting blade, giving you messy strips and potentially damaging your machine. It also slows down your work significantly. If you absolutely must work with curled wire, use the adjustable feed hole setup (Method for tricky wires), but try to make this the exception rather than your go-to approach.

4. Insufficient Component Tightening

Getting clean, consistent strips starts with proper tightening. It's a simple step that many people skip, but loose parts can ruin your stripping results. Here's what you need to check:

1) Locking Nuts

Your blades need to stay exactly where you set them. Turn the locking nuts until they hit the middle of the adjustment screw - they should be tight enough that the blade won't budge. If you're having trouble getting enough force by hand, grab an adjustable wrench.

2) Blade Adjustment

Start by turning the adjustment knob counterclockwise to raise the blade. Then lower it carefully until it touches your wire just right. Once you've got the perfect position, lock it down with those nuts. Always give the blade a quick check for any movement before you start stripping.

3) Guard Securing Bolts

After any adjustment, tighten both guard bolts completely. Make sure they're equally tight - a loose guard can throw off your entire operation. It's worth taking a quick look at these bolts throughout your work session.

Expert Tip: If you notice any wobbling or inconsistent stripping results, always check component tightness first before making other adjustments.

5. Troubleshooting Common Issues

If you encounter problems during operation, check these frequent causes:

6. Conclusion

Avoiding these five common mistakes will significantly improve your wire stripping results and extend your machine's life. Remember:

• Always match wire diameter to the correct feed hole
• Ensure proper guard height adjustment
• Use straight wire whenever possible
• Maintain tight components
• Never skip practice and setup steps

Many users initially struggle with wire slipping in their automatic wire strippers. After testing the CREWORKS wire stripper extensively, we found that most slipping issues aren't actually machine defects - they're setup and technique problems that are easily fixed.

While this machine has proven reliable for both small and large-scale wire stripping projects, getting the best results requires understanding a few key techniques. Hope you find this guide helpful to you to avoid common mistakes and get the most out of your investment.

FAQ Section:

Q: Why does my wire keep shifting during operation? 

Check feed hole size matches wire diameter and ensure guard height is properly adjusted. Remember to use straight wire whenever possible.

Q: How often should I check component tightness? 

Verify all components are secure before each use and periodically during long operations.

Q: Do I really need to practice with scrap wire? 

Yes, practicing with scrap wire is essential for proper blade adjustment and consistent results.
