What are welding magnets?
Welding magnets are magnets with very high levels of magnetism shaped at particular angles to assist the welder.
They are used to hold workpieces together through magnetic attraction so that welders can weld, cut or paint metal material.
They stick to any metal surface and can hold objects at various angles. Welding magnets assist with alignment and with accurate holding.
They make every welding project easier and smoother because they allow you, the workman, to free up your hands so you can safely work on your project.
Because you don’t have to hold your workpieces in place, your weld is both straighter and neater. They also help with setup and give you strong and accurate holding, while you weld.

Buyer’s guide: features to consider when buying welding magnets
Before choosing welding magnets, the first practical consideration is deciding what type of welding your project requires.
You will then be in a position to purchase the best possible tool for your budget and for your needs.
If you are creating standard steel shapes, then you could look at a magnet with a fixed angle. If you need the magnet to hold your workpieces at different angles, then you will need to look at multi-angle magnets.
If you primarily handle lightweight materials, then you do not need a magnet with a very heavyweight capacity.
Number of angles the welding magnet provides
As the name suggests, multi-angle welding magnets can hold workpieces at different angles – 45, 90, and 135-degree angles. These are ideal for assembling, marking off, pipe installation, soldering, and welding.
Obviously, the greater the number of angles the welding magnet provides, the more useful it is for a wide range of applications.
Does it have an on/off switch?
There are two primary types of magnets – electromagnetic and permanent. The primary difference is one type allows you to switch the magnet off and on, while the other is always magnetized.
A welding magnet with an on/off switch allows you to control the magnetism which means you don’t have to worry about the magnet sticking to your workbench or attracting any of the other tools in your workbox.
With this feature, you can leave the magnet off until you are ready to work.
It is important to ensure that the weight capability of the magnet is strong enough for your purposes. Some magnets only support small weights up to 25 pounds but some have weight capacities up to and beyond 200 pounds.
If you handle primarily thin, lightweight materials you don’t need a significant weight capacity.
There are many middle-weight magnets available, which have a capacity of between 50-100 lbs. This is usually sufficient for a wide variety of applications.
Material strength and durability are important for any tool. The magnet needs to be made of high-quality steel and should be powder coated to prevent rust and corrosion.
