look up light activated resin...basically, it's kinda like an epoxy resin that only hardens upon exposure to UV

Buy a real plastic welder.

weak fragile plastic doesnt adhere well to a lot of surfaces you get what you pay for.

I have no idea what the hell that shit in your picture does, but it's estimated that the bond strength between two pieces of plastic that are chemically welded together is about 80% of the strength of an equivalent single piece.

i'm not really sure either just saw it in a local flyer for $20. i think it's supposed to be basically a soldering iron but with plastic and it uses a UV light to harden it or some shit

I don't have whatever that is, but I do have a soldering iron type plastic welder. It works all right for simple repairs, where it has paid for itself several times over. A few things to keep in mind: Use a plastic filler that matches what you'll be welding. The "general purpose" filler sticks sold for plastic welding suck. Plastic is made of long molecules, and to get a decent bond, you'll have to stir the melted plastic so that the plastic molecules bridge the gap. Just butting one drop of liquid plastic against another and letting it cool will not make a very strong bond. And it probably won't be as strong as the original unless you build up the thickness a bit. Embedding a bit of fiberglass mesh into it is a good idea if it needs to take impacts or bending stress.
