I've got not exactly a welding question but you should be the right group of guys to ask.
I'm looking for a portable rig I can use for those times when I'm in the middle of tearing something down and need to get a fastener red hot. Taking a motorcycle to work's oxy/act rig isn't always feasible when it's half torn down and getting the resulting broken off bolts out has not a bit of fun.
Is a portable oxy/acetylene rig the most sensible choice? Recommendations for a red hot rig?
