  • Thanks for sharing I’m just getting into plastic welding! I have a question can you plastic weld PVC?

  • Didn't realize a soldering iron worked so well with plastic, thanks for helping fix my keyboard.

  • I used a steel nail with the same thickness as the original soldering tip. The (flat) nail-head works perfectly for a tip and because its made out of steel it doesnt burn the plastic as fast as copper would, meaning less (toxic) smoke and a more relaxed melting of the plastics while operating it.

  • Cracks tend to grow. Always drill a small hole at the end of the crack to stop it from spreading then continue with the weld. Thanks for the video.

  • Who else broke their headphones and was wondering if this was a viable method of repair

  • Thanks! Fixing an important piece of plastic and this makes it simple!

  • This works great. My mower hood is polycarbonate. Stitched right back together. Just wish I could find something red polycarbonate to use for filling holes and missing bits. Any suggestions?

  • I used some 1!2 inch staples on a trash can that split and just put the iron on the staples until they melted through, I think that part may be the strongest part of the can now lol
