Floor pans almost complete - next job will be cutting out and replacing rotten rear quarter panels. Should be a relatively straight forward job, but I'm unsure on what type/method of weld to use on the rear external seams. From factory I believe these were continuous spot weld, but I don't have the equipment to achieve that (I'm using MIG). What alternative methods should I use?
E.G.
a) plug weld with inch spacing
b) as above but additionally run a continuous seam internally
c) buy a spot welder and attempt a continuous spot weld
d) other suggestions???
Cheers,
Colin.

If you have a spot welder then you can do a combination of spot welds and plug welds. Otherwise like i did plug weld with inch spacing.

If you're confident working with mains electricity then you could have a go at building a spot welder

If any of the instructions/parts aren't clear to you then I'd probably not bother because Microwave transformers can easily be lethal if you don't know what you're doing.
It should cost less than £10 if you can find an old microwave.

That looks like a very drawn out way of killing yourself.

To be honest and from a safety point of view don't attempt to build your own. Just looking at one that was made showed no covering over live components. Fair play the OP mentioned that unless you were a skilled electrician it can be lethal. If it was to fail or damage you your car or your house then there would be no insurance company in the world who would pay out.

As much as I like Instructables (and am fully capable/skilled to build one) I have to agree with sonik - it's an accident and legal liability just waiting to happen. If I were to go down the spot weld route then I'll buy one from my local tool store for $160 (100 quid) and feel a lot safer.
