Symptom-first troubleshooting
Birdnesting Troubleshooting
Troubleshoot MIG wire birdnesting at the feeder using liner, contact tip, drive roll, gun cable, and setup checks.
Beginner Explanation
What this means in plain English
Birdnesting is when wire piles up at the feeder instead of traveling smoothly through the gun. Start with the liner, drive roll, contact tip, and gun cable path.
