I keep the hand shield in the carry case as it takes up very little room . I do not however have the tig torch stored within the carry case ,but rather i have 3/32" and 1/8" 7014 and 6013 along with the small chipping /brush and welding gloves.
This way it is very portable and if i happen to forget to have a helmet handy i can always use the supplied mask that is provided.
As of yet i have never had occasion to use it but you never know with my absentmindness i am sure i will need it sooner rather than later.
Cheers
