The Strong Hand Tools Adjust-O Heavy Duty Magnet Square (MSA46-HD) is designed for professional welders and fabricators who require precise, reliable workholding for metal projects. This heavy-duty tool offers the significant advantage of switchable magnetic force, allowing for easy positioning and cleanup; however, users should note that its bulkier profile compared to fixed magnets may require careful planning when working in tight, restricted spaces.

It will only work on ferritic stainless steel grades that are naturally magnetic; it will not work on austenitic grades like 304 or 316.
The MSA46-HD is designed for heavy-duty fabrication and provides sufficient force for most standard square, round, and angle iron applications.
Yes, it is designed to hold your workpieces in place during the tacking process, though direct, prolonged contact with the welding arc should be avoided.
No, this is a mechanical, switchable permanent magnet; it requires no external power source.
Keep the contact faces clean of metal debris by switching the magnet off after each use and wiping the surfaces with a rag.
Check that the surface is clean and free of thick paint, rust, or debris, as gaps between the magnet and workpiece significantly reduce holding power.
Ensure there is no heavy build-up of metal filings inside the switch mechanism; clean with compressed air or a soft brush.
Using the tool is straightforward: place the square against your metal stock while the unit is switched off to align your angles correctly. Once satisfied with the positioning, rotate the switch to activate the magnetic grip. When finished with your weld, return the switch to the off position; this allows any accumulated iron filings or dust to be easily brushed away, maintaining the tool's effectiveness. Avoid exposing the tool to extreme heat directly from a cutting torch or prolonged direct contact with a welding arc, as excessive temperatures can compromise the permanent magnets inside. Store in a dry environment to prevent corrosion.
