Can downdraft tables be used for welding?

Downdraft tables or benches are sometimes used for welding, but they are not always the best option. For welding and other thermal applications that produce submicron particulate, a backdraft table is usually preferred. That is because weld fumes rise as they are created. A downdraft table, which creates a downward airflow, may miss fumes that rise too quickly to be captured. These fugitive weld fumes end up in the welder’s breathing zone or escape into the wider facility. Downdraft tables may also present a fire risk when used for welding.
