With simple adjustments, a smoke extraction welding gun devours fumes and leaves shielding gas around the welding bead whether the welder works at a work bench or on a 30-ft ladder. Diverting arsenic, beryllium, chromium, cobalt, lead, manganese, mercury, nickel, silver, and vanadium fumes from a welder's breathing area is as critical to health as eye protection and leathers. As with most safety devices, ease-of-use plays a role in user adoption. Weight of a gun-extraction unit is key for Bob Gardner, who tests welding equipment and supplies for GASES & WELDING DISTRIBUTOR. Climbing up ladders or crawling around pipes are often requirements of his welding projects.
