Many times you can just use a hot solder gun to do plastic welds. I have made repairs to cracked plastic by heating it and melting the plastic to form a weld. With this method no welding rod is required. Plastic welds are not the prettiest thing in the world. Iwould not do in a aarea that was visiable.

Anybody remember the toy years back where you build a working dragster or other car? It came with plastic I-beams, rivets, and such. You'd cut and weld everything together with a little hand held motor called a "spin welder". Came with loads of little plastic rods that slip over the nipple that protruded out and spun. The friction would melt the plastic rod and the work piece, and you could actually create a nice looking bead that was strong. It was pretty cool, it kept our old refrigerator alive way past it's "due date." Anyway, wouldn't mind finding another for those odd plastic welding jobs.
Just a thought. Would be much for big jobs, though.

good ones cost around 350 bucks and use hot air.you use a filler rod stick in the process.its much like gas welding.
hippyheads statement is true.the type of plastic is key to success.some plastics work better than others also.where ive seen (and used) professional plastic welds is on 4 wheeler fenders.to have a honda or suzuki fender welded is 5 bucks an inch at local dealers here.
plus you live with the scar since the color is the plastic.no paint.
but hey 30 bucks for a 6in tear beats 150 dollar fender.
newer snowmachine cowlings are some kinda weird compound that doesnt seem to weld worth beans btw.
