Hello, I have been given an old Sealey Supermig 180/1 and am going to have a go at restoring an MGB. I have read as much as I can from this forum, and managed a few welds. Most of the welding I will be doing, initially at least will be puddle / spot welding.
First question I have is what size of hole to use? I have a tool ( a joggle jodle joggle...I can't spell it) that punches nice 5mm diameter holes which makes a nice neat job. elsewhere on this forum I have seen 7mm recommended or even larger.
Is 5mm diameter acceptable for sills etc?
I also have issues blowing holes in thin metal when trying to butt weld ( think about 0.8mm to 1.0mm thick...pieces cut from an old bonnet) I am practising on this now and assume it to be trying to weld for too long a duration and not moving the torch fast enough. I am thinking unless my technique improves instead of butt welding sheets together I might joggle (there's that word again) and overlap sheets and spot weld using 5mm diam punched holes (or 7mm diam?) to give a "safer process"
Appreciate any guidance
