For about 7 years I did my brazing outside, because of space not landlordship. I got a 8'x8' event (pop up) tent with additional sides for wind and rain protection. This did well enough although in hard rain or strong winds I learned to put off the brazing session. The other aspect I had to relearn was to watch my flux as the light/color outside was far different then inside work. It was hard to see the steel start to change to dull red. I kept my tanks and torch in a tall Rubbermade cabinet (which I locked) on the patio. Andy.
