Are they any good?

Would anyone want any welding done?

we used to have one where I was made redundant from. That worked OK, just practice. It was just a heater inside & you fed it with low pressure air so it produced very localised hot air. Then you need a suitable filler plastic rod.

Going back on topic .......

I use something similar to this 
http://cgi.ebay.co.uk/NEW-SMD-REWORK-DESOLDERING-STATION-SOLDERING-IRON-/380256134365?pt=UK_AudioElectronicsVideo_Video_TelevisionSetTopBoxes

Primarily for SMD rework, but the temp will go down to about 100C, so will melt plastic OK. I used it to stick my power sounder back together once I replaced the batteries, worked OK.

Mmmm,nooooh....(I think)  the ones I've seen are far bigger and totally hand held, gas powered flame, or possibly soldering iron style, with a a beed of plastic fed in on a trigger. Main trick is matching the correct plastic beed to the part being welded, ok omega bumpers will be all the same to a point I would think, but matching flame heat, trigger speed and movement of the gun takes a bit of fiddling around iirc.

But on the other hand, the main application I witnessed was repairing bike fairings(not all of them mine  ::) ) where the manufacturers chopped and changed plastic types year on year and to achieve different colours I think, so it may be easier on one make of car...?

Anyway, Mr Imber, have we cracked a bumper per chance?

You can draw an analogy with metal welding here. The hot air devices are like gas welding, what Chrisgixer described, feeding in the filler rod sounds like a Mig welder. Both techniques will work, although for fixing a crack that doesn't need filler the hot air might be better. Plus it would be handy for removing/replacing SMD components, as found in key fobs......

Yeah, would depend on the application.....?

Large split in the front panel of the caravan, this is Baileys fault not mine.

Was going to do MEK and ABS extrusions but Plastruct have gone styrene, and MEK is not easy to get anymore.

Found the plastic welding and thought hmmm.

Got a cracked A frame cover as well
