The BESSEY WMS-5 Magnetic Hold Down Square is a specialized tool designed for welding and fabrication tasks. It combines a magnetic base with an adjustable square to hold metal parts at precise angles during assembly or welding. This review examines its features, performance, and suitability for different users.
In real-world use, the WMS-5 is typically employed in metalworking shops, garages, and on job sites. A welder might place it on a steel plate to hold a vertical piece at a 90-degree angle, freeing both hands to tack weld or adjust the fit. The magnetic base attaches firmly to ferrous metal surfaces, and the square’s arm can be adjusted to various angles, making it useful for tasks beyond simple right angles. It’s particularly handy for assembling frames, brackets, and other structures where maintaining alignment is critical.
Key functional features include a strong magnetic base that provides holding force on steel and iron. The square arm is adjustable and can be locked into position, allowing for repeatable angle settings. The tool is made from durable materials, with a metal construction that resists heat and spatter common in welding. The magnetic base has a release lever to easily detach the tool after use. The WMS-5 is compact and portable, with a handle for convenient placement.
However, the WMS-5 has limitations. Its magnetic hold is effective only on ferrous metals; it won’t work on aluminum, stainless steel (unless magnetic), or non-metallic surfaces. The holding force is sufficient for light to medium-duty tasks but may not secure large or heavy workpieces without additional clamps. The adjustable mechanism, while useful, can be a weak point if not tightened properly, leading to slippage. Also, the magnet can attract metal shavings and debris, requiring regular cleaning to maintain performance.
Compared to alternative tools like traditional welding clamps or magnetic squares from other brands, the WMS-5 offers the advantage of adjustability and a strong magnetic base. Traditional clamps may provide more holding force but lack the integrated angle-setting feature. Generic magnetic squares are often cheaper but may have weaker magnets or less precise angle adjustments. The WMS-5 sits in the mid-to-high price range, reflecting its build quality and brand reputation.
Who is it suitable for? Professional welders and fabricators who frequently need to hold metal parts at specific angles will find the WMS-5 a valuable addition to their toolkit. It’s also useful for DIY enthusiasts working on metal projects, provided they understand its limitations. It is not suitable for those working primarily with non-ferrous metals or for tasks requiring extreme holding force. Hobbyists on a tight budget might opt for a basic magnetic square instead.
In terms of performance, the WMS-5 does its job well within its intended scope. The magnet holds securely on clean, flat steel surfaces, and the adjustable arm allows for angles from 30 to 90 degrees (or more, depending on the model). The build quality feels robust, but it’s not indestructible; dropping it or exposing it to excessive heat could affect the magnet’s strength over time. The release lever is a nice touch, making removal quick without disturbing the workpiece.
Overall, the BESSEY WMS-5 is a niche tool that solves a specific problem: holding metal parts at angles during welding. It’s not a universal solution, and its limitations mean it won’t replace clamps entirely. But for those who need it, it can save time and improve accuracy. The price may be a barrier for occasional users, but for professionals, the investment may pay off in efficiency.
