It's bad to breath any kind of smoke/fumes but Nickel, chromium and Zinc are particularly bad with Zinc probably being the worst since the short exposure is MUCH more sever. This is easy to deal with and 3M,Norton and a couple of others make very good disposable welding fumes/dust masks although some of these are a bit pricey. A paint respirator works ok and I use my old expired 3M activated Carbon cartridges for welding because filtering heavy metal fumes is a lot easier than ISOs in paint so they are still good for this, seems like the prefilters remove almost all of it before it reaches the cartridges.
