The bessey wsm12 is a heavy-duty welders angle clamp designed specifically for steel construction, welding and metalworking applications. Offering substantially larger clamping capacity than the wsm9 model, with almost twice the jaw height, this professional-grade corner clamp excels at holding, fixing and aligning materials at precise 90-degree angles. Built for demanding workshop environments, the wsm12 features sturdy jaws and a robust base plate manufactured from high-quality cast iron for exceptional durability and stability. The copper-plated spindle is specially designed to prevent welding splatter from adhering to the thread, ensuring smooth operation even in intensive welding applications. With a generous 120mm maximum opening and 120mm jaw length, this clamp accommodates a wide range of workpiece sizes whilst maintaining precise right-angle alignment. The intelligent design provides a clear, unobstructed working area, allowing welders and fabricators to access the workpiece freely during welding, assembly work and when fixing t-joints. The automatic adjustment feature adapts to workpieces of varying thicknesses, streamlining setup time and improving productivity on site or in the workshop.
