I've welded a lot of corral panels, galvanized, always outside, and always from the upwind position, with a respirator the last few years only, before that I just "did the job".

But, I just had a kidney removed for cancer and the docs say it can be a result of "exposure to industrial chemicals", and the zinc does come to my mind from time to time as an "industrial chemical".

I recommend other ways to take a vacation and to spend your money on.

If you want a power hammer but can't find the money ask yourself about coming up with the copay for the surgeon and hospital for kidney removal, and unless you are fortunate enough to have truly good health insurance you will find the answer the question on how to raise the power hammer money, but without a power hammer to show for it.

So, my short answer is, don't do it.
