The crack is about 5cm below the starter shaft and I'm worried it might be getting larger.
You can generally weld mag with commonly available rods no problem. However if this proves to be impossible, then get a scrap case and cut this up to make filler material. Repairing with epoxy makes welding much more difficult, as its very hard to get rid of the epoxy completely before welding.
