Just a little tip for people new to welding, it was mentioned in the Tutorial about cooling thin mettle, using a damp cloth to cool the mettle being welded.
I always use a small hand held gardeners spray bottle, those small one's you can get from Garden center's for about a quid or so, you can even get them at wooly's, ASDA, in fact almost anywhere these days.
They are brilliantly effective, the pressure adds to the effectiveness of the water, just a little squirt has great effect, i usually do a short run of weld, then a spray, another short run of weld, and then another spray, and carry on like that till the job is done.
Its also handy if you have to weld a car floor with a Mig,from underneath with out removing the carpets, (although its not recommended, and absolutely NOT WITH OXY ACETYLLENE) I have done this many many times, and never caused a fire, although i have always had some one watching from above just in case, with either he hose ready or a bucket of water, and another hand held spray, and this in nearly every case, does away with removing seats and carpets.
Handy when fitting new sills too, i am always afraid of setting fire to paint work inside the sills, also when under seal catches fire, particularly in hard to access places, you will find that, pressurized water puts flames out far better than just throwing water on to flames.
The spray bottle nozzle should be loosened to give a single jet of water, not a spray setting. Its a brilliant little tool, and cheap.
