FabMaster adds welding fume extractors for South African fab yards

FabMaster Workshop has expanded its Germiston product line with FumeArm welding fume extractors for fabrication shops across South Africa. The move targets yards that still depend on open doors and roof fans, as safety rules push welders to control fumes at the source.

Why it matters: - Welding fumes are a serious workplace hazard, and South African fabrication yards are being pushed toward source capture instead of general ventilation. - FabMaster Workshop’s new extractor range gives shops a way to control fumes at the arc in fixed bays and mobile work areas. - The product line is aimed at trailer builders, steelwork contractors, mining and municipal maintenance shops, and catering equipment makers.

What happened: - FabMaster Workshop, a Germiston supplier of fabrication bay gear, added the FumeArm welding fume extractor to its range. - The units are available in mobile and wall-mounted versions. - The mobile version runs on 230 V and moves on castors. - The wall-mounted version runs on 400 V and is designed for fixed bays. - The extractor uses a self-supporting arm that is 3 m or 4 m long. - A 160 mm capture hood sits at the weld position. - The fan moves about 1 100 m³/h through the hood.

The details: - Fume passes through a spark pre-separator before it reaches pleated filter cartridges. - Cleaned air returns out of the cabinet. - Standard units pulse-clean the cartridges automatically with compressed air at 5 to 6 bar when the fan stops at the end of a shift. - Dust falls into a closed bin. - A front gauge shows when the cartridges need replacement. - FabMaster Workshop fits W3-class cartridges for stainless and high-alloy work. - The company says the unit is for welding fume only, and grinding should go on a separate spark-contained grinding deck. - FabMaster Workshop says the mobile unit draws roughly 1.1 kW while running.

Between the lines: - The timing fits a tighter safety environment. Welding fume was classified as a cause of cancer in people by the International Agency for Research on Cancer in 2017. - Mild steel wire can add manganese. - Stainless work can release hexavalent chromium and nickel. - Galvanised gate and railing work can produce zinc oxide, which causes metal fume fever. - The Regulations for Hazardous Chemical Agents, 2021 under the Occupational Health and Safety Act expect exposure to be controlled at the source where possible. - FabMaster Workshop’s advice points to a common failure in workshops: the hood is often parked too far from the arc, which reduces airflow capture. - The company’s bay layout lead said the hood should sit within 200 to 300 mm of the arc and slightly behind the weld so smoke rises into it. - The company also says the hood should be moved as the weld moves along the seam. - FabMaster Workshop covers power-cut planning in its setup advice. - The fan does not restart by itself, so workers should not strike an arc until the extractor is running again. - Yards using generators during outages should account for the mobile unit’s running load and start current when sizing the genset. - For four or more fixed bays, FabMaster Workshop says a central ducted system with one fan can cost less to run than separate units.

What’s next: - FabMaster Workshop is quoting on both individual units and central ducted systems. - Customers are asked to provide a rough bay sketch, the processes and metals they weld, the reach needed from the mounting point, and the power available at each bay. - The company is positioning the extractor range for South African fab yards that want compliant fume control without relying on roof fans or open doors.

The bottom line: - FabMaster Workshop is betting that South African fabrication shops will move from passive ventilation to point-of-capture extraction as safety expectations and enforcement pressure rise.
