TIG is what is used with chromoly cages, and many people use TIG to do mild steel cages. Having done both TIG and MIG, putting a MIG gun into tight spaces is not fun. Same for TIG, but the torch is smaller and easier to reach tight spaces, but it does require attacking the weld from both sides with the filler rod and torch. The heat is easier to manage, and the welds are better quality, but the time is night and day different, which is why I think they went with MIG for this, as it is for function over a show car, and it is so over-powered, chromoly is not needed.
