After the van being off the road for the last 12 months due to various rot issues that need sorting for the MOT, I decided to have a go myself and bought a MIG welder a few months ago (Clarke 151).
I've never welded before but been doing loads of reading on here (especially metalmicky's exploits) plus on the migweldingforum and have got a couple of mates that can weld and have offered loads of advice. Will be doing loads of practicing in the garage when I can clear some space.
I have bought the main panels I reckon I need (so far anyway!


My question is, having done as much reading as i can find on here and Google, how do I weld the lower outer sill panel I bought from Schofield's? I have the short panel from the first horizontal seem down (will try and post a pic later when I can work out my new iphone

All of the posts I can find are for fitting the taller panel that goes up to the swage line but our van is solid above the seam and the floor is all ok, (I have already removed the interior), so I didn't want to chop out more than I have to.
I can see I need to puddle / plug weld along the bottom edge which is fine but how do I weld / attach the rest - top of panel / sides?
Also, to remove old panels with spot welds, is it best to use a spot weld drill then separate the panel or to grind the spots out?
Thanks for any help...
