    Just wondering would anyone be able to advise me where I could get plastic welding courses. I have searched on the net and all directing me to UK or USA, I would rather a course in Ireland if possible.

    dunno why you're shocked - hard to make a living at it on it's own.......

    But loads of people to plastic welding - a lot of the car shops have the equipment, and the equipment sellers usually offer that to them.

    The best equipment (imho) on the market, comes from Leister - and you'll find the equipment, here: http://www.welwyntoolgroup.com/vehicle-repairs.aspx

    Here's their how-to video. They do have agents in Ireland btw.

    Those Leister welders are also quite common in some areas of the roofing industry - if you know any roofers that haven't emigrated yet, you might get lucky.

    True the same guns - just different nozzles, which you can buy.

    Or, there used to be lots of them in the PC manufacturing co's of the industrial estates of Dublin at one stage..........

    hi could anyone tell me what the difference is between these plastic welding kits and a heat gun with a plastic welding rod, considering that these welders cost around 160 euro and a good heat gun costs around 50?

    also can anyone tell me what best type plastic rod to use to bond polyethylene plastic?

    I'd say you'll be prone to warping what you're welding if using a heat gun - far too inprecise I'd have thought

    could you get away with a good variable temp soldering iron I wonder?

    hear people using cable ties as welding material. And I've seen someone using offcuts from a cut up rear fender (offcuts from diy tail tidy iirc)

    Polyethylene need to be welded with polyethylene, it comes in thin rods that you feed down the nozzle of the welder and move it along.
    Its not that hard to do, but like any welding practice makes perfect.
    The nozzles of the welder have a V that makes the fillet and the the rod fills the V as you move along the weld. This is to ensure that the weld has a maximum of surface area.

    thanks, would the broke piece of polyethylene that i am trying to weld back together have to be heated as well as the welding rod? like would the heat from the welder not distort the plastic on the broken pieces?

    Yeah, cheap soldering iron and cable ties is what I use. Also to strengthen the weld insert staples or similar. Lay staple across the join, place soldering iron on the staple and as the staple heats up it softens the plastic and sinks in.
