The 10 Best Plastic Welders
This wiki has been updated 18 times since it was first published in October of 2017. If you need to mend a cracked plastic item, then fusing the damaged pieces together is a stronger option than using glue. These high-quality welders ensure your fixes stay in place for a long time, as their heating assemblies can precision-melt even polypropylene. They are ideal for kayaks, rafts, water tanks, valve handles, and certain car parts, and can save you a bundle on professional repairs.

In this update, we've added the JounJip 110-Volt, an affordable and comprehensive kit that includes lots of accessories that will make your job easier, like a heavy-duty wire brush for scraping off excess plastic after soldering and a hands-free stand that can hold your hot iron without you having to touch it or worry that it will fall over. We also decided to add the Nobrand 0THS-001, which, as a hot stapler, works a little differently from the other models on this list. The staples used at the tips are thin, best for smaller jobs, and deform after several uses- but you get two hundred of them, so you're unlikely to run out anytime soon.
The devices listed here have very little in common with arc welders, the extremely powerful high-voltage machines used in arc welding. The welding helmets, welding gloves, and welding blankets often associated with welding aren't necessary for plastic welding, which does not emit UV rays or blinding light or as much heat as arc welding, but safety is still important, and you should be sure to keep your hands away from the soldering iron at all times.

The Polyvance 5700HT Mini remains an impressive choice, as it provides a powerful motor in an easy-to-use package. The Hobie KC Pro is a strong option as well, because it's resilient enough to use all day long for several years. That said, all of the other options on this list are high-quality as well, and will certainly allow you to get the job done.
