Why should it be tig? If its standard 1026 DOM cage and not something else a 70 thousand filler rod ( mig or tig or even stick for that matter ) is the same. You get a little better heat control out of the tig, but its not needed here.
Even if the Cage is a chrome molly tube just use the correct filler wire like a 80 thousand filler and you can still mig it. Heck even if its T-1 tube ( which they don't make ) use a 100 thousands filler for a mig and your welds will be fine.
Its the filler making the weld that gives it the strength not so much process. Yes tig can offer a better a way of controling the heat but it can also be a bad thing.
Lets say you have a bad fit and a gap needs to be filled in, now your putting alot more heat from the tig toarch to fill that gap, were mig will fill it easyer with a lower heat count and less stress in the HAZ zone.
So to wrap it up tigs cool to say but not needed for a standard cage build, but if you want to pay a welder maybe 3 times the standard rate ( thats what I would get for a tig cage ) then gor for it.
