It works great if you have a vaccum pump, it will pull crap into the joint http://www.leisuretimeok.com/service/cracks.htm schmear pellets Try pvc primer if it starts to soften plastic good to go you will need the pvc primer if you go with shmear |

I purchased a kit from Snap On that comes with multiple types of rods and flat pieces of different types of plastic filler. Has instructions and video. The trick is identifying the type of plastic your putting together. That way you can use the proper filler. If you use to much heat it will make the repair point more brittle. It takes some practice but works well.

if you can spare a piece of the base material you can use that as filler (works when welding metal and cannot identify the exact material type).
a buddy of mine modifies his glocks by cutting out a wedge, heating the frame and shaping it, then using the removed section to weld the seam back together with a soldering iron. if not, try contacting the manufacturer of xyz product and see what materials they use. |

It takes some practice but works well. We have the same kit at work, I end up using epoxy to fix what is broke. It does work ok for cosmetic damage not so for strucural repair on say an A pillar mount. Harbor freight has a kit similar to the SO. |

Quoted: I have some small repair projects that I've been considering buying a plastic welder for. I've read that IDing the plastic can be difficult and is essential to using the correct rods/filler. Anyone here do it? Used to do a lot of plastic welding - pvc, ldpe, hdpe, pu, pp, abs, etc. Cleanliness is key, next to using the right filler rod. Being able to weld also helps, although I taught hundreds of people how to do simple welds. What specific questions do you have? |

I have done quite a bit of drive belt welding with a specialty kit. Too bad that machine was a shitty design.

I used Urethane Supply company's Plastifix kit and it worked great.

Solder uses filler that melts below around 800 F. Filler above that is brazing. Melting the base material is welding (with or without filler). |

I used a soldering iron and a zip tie as filler on a radiator nipple for the catch can that broke off. Still holding 1.5 years later :)
