TIG Welding Fumes A small but toxic by-product of TIG welding is the generation of ozone, nano-particles (less than 100 nm) and off-gassing of the molten metal. Nano-particles are especially harmful to human health because of their ability to penetrate inside the respiratory system and enter the blood stream.

Inhaling large amounts of zinc (as zinc dust or fumes from smelting or welding) can cause a specific short-term disease called metal fume fever, which is generally reversible once exposure to zinc ceases. However, very little is known about the long-term effects of breathing zinc dust or fumes.
