The Amtech Welding Magnet (S4620) is an essential tool for fabricators, welders, and DIY hobbyists who require an extra set of hands when positioning ferrous metal pieces. By providing reliable, magnetic clamping, it ensures fast and accurate alignment for welding, soldering, and pipe installation; however, users should note that its magnetic strength is limited to 11kg, making it unsuitable for heavy structural steel projects.

No, this magnet is only effective on ferrous metals like steel and iron.
It is recommended to use the magnet for initial alignment and tack welding only. High heat from prolonged welding can weaken the permanent magnets over time.
The magnet is rated for a maximum holding capacity of 11kg (25lb).
Yes, the magnet is precision-machined to hold at 45, 90, and 135 degrees consistently.
Yes, like all strong magnets, it should be kept away from pacemakers, credit cards, and sensitive electronic equipment.
Keep the faces clean of debris and avoid subjecting the magnet to excessive heat, which can demagnetize the internal material.
Check the workpiece for thick coatings like paint or rust; grind the surface down to bare metal for a stronger magnetic connection.
Use a dry shop cloth or a piece of masking tape to lift away accumulated metal filings.
Verify that the workpieces are flush against the edges of the magnet; if the workpiece is warped, the magnetic connection may be uneven.
To use the magnet, simply place it against the metal joints you wish to align at the desired 45, 90, or 135-degree angle. Ensure both workpieces are ferrous (steel or iron) for the magnet to engage. After use, wipe the magnetic surfaces with a clean rag to remove metal dust and iron filings, which can build up over time and interfere with the seating of the magnet. Store the tool in a dry area away from electronic devices or magnetic sensitive storage media.
