Xtra Whip - Nitrous Oxide Whipped Cream Chargers (24) for butane/ox mini welder
Chargers work fine in my mini Butane/Oxygen welder/brazer wfhen I need high temps for my hobby. . The Ox charger only lasts a few minutes, buts that's long enough for little jobs. A bit bigger job requires using 2 or more chargers.
Even made some whipped cream with one charger and it worked great (better with a little sugar in the cream).
