Bessey BDMS-1 Magnetic Welding Fabrication Square

Product Description

The BESSEY BDMS-1 is a magnetic welding fabrication square designed to hold workpieces at precise 45-degree and 90-degree angles during welding, fabrication, and assembly operations. Built around a ferrite magnet with a 100-pound average pull force, it delivers firm, consistent holding power on ferrous metal surfaces. The T-handle release mechanism allows the magnet to be disengaged quickly without prying or repositioning. At 8 inches wide, 8 inches high, and 1-5/8 inches deep, it fits comfortably alongside most welding setups. Fabricators, pipe fitters, and structural steel workers use this tool to tack-weld corners and joints accurately without a second set of hands.

The BDMS-1 is suited for light structural fabrication, sheet metal work, and general-purpose welding fixturing in both shop and field environments. Its dual-angle capability makes it useful when setting up square frames, box sections, or angled joints. The compact profile allows it to be placed close to weld zones without interfering with torch or electrode movement. Welders working solo on repetitive joint setups will find the consistent magnet engagement and quick-release handle reduces setup time on tack welds.

Key Features

• 100-pound average pull force for secure workpiece retention on ferrous surfaces
• Supports 45-degree and 90-degree holding angles for versatile joint setup
• Ferrite magnet construction provides stable, consistent magnetic field
• T-handle release mechanism for fast, controlled magnet disengagement
• Compact 8 inches x 8 inches footprint fits tight weld zones

Compatibility

Designed for use on ferrous metal workpieces in welding and metal fabrication applications. Functions as a standard magnetic welding square for shop or field use on flat and structural steel stock.

Installation Notes

Position the square against the workpiece before activating the magnet, then verify angle alignment with a separate square or level before tacking. Keep the magnet face free of weld spatter and metal debris to maintain full holding force. Use the T-handle to release the magnet rather than twisting or prying the body, which can stress the housing over time. This tool is intended for fixturing only and should be removed before final welding passes that generate prolonged heat near the magnet.
