Magnetic Welding Square — 41 lb Pull

The Bessey WMS-7 is a compact magnetic welding square that delivers 41 lb of holding force. Its rare-earth magnet grips ferromagnetic workpieces at 45 and 90 degree angles without a mechanical switch. A 1/4 inch centre hole allows bolt-down mounting or use as a pivot point. The steel housing measures 4.8 in long, 3.3 in wide and .6 in high.

For Tack Welds and Quick Set-Ups

Welders and fabricators who need fast, repeatable corner alignment on thin plate will benefit from the instant on/off action. The fixed angles and moderate pull force limit its use on heavy structural sections or where variable angles are required. Buyers who need adjustable angles or higher holding power should look at other solutions.

Fits in a Tool Belt or Fixture Plate

The low .6 in profile and .56 in plate thickness let the square sit flush on a workpiece or fixture plate without raising the joint. Its small footprint frees up bench space compared with bulkier C-clamps or angle irons. The centre hole accepts a 1/4 in bolt for semi-permanent mounting on a welding table or jig.
