My employee wants to make a titanium roll cage for his high performance
remote control monster truck. We have a good 185 amp tig welder, and he's
pretty good at using it. We are using argon as a shield gas.

The problem is, we've never worked with titanium before. Can it be Tig
welded? Can we use stainless rod, or should we get something else. Is the
argon OK?
