The size of a 90 degree angle weld clamp magnet refers to the height and width of the weld clamp magnet. The size includes the casing within the measurement. This means the size does not necessarily refer to the size of the magnets within the device
90 degree angle weld clamp magnets range from 126 x 126mm (5″ x 5″) to 300 x 300mm (11.8″ x 11.8″) in height and width.
The depth of the 90 degree angle weld clamp magnet ranges from 22-35mm (0.9-1.4″). The depth of the 90 degree magnet refers to the width of the two magnet sections, not the size of the interlinking bar.
The pull force of these magnets range from 40kg to 200kg.
The best size of 90 degree angle weld clamp magnet to have for everyday use would be the 126 x 126 x 22mm. This is because it can hold an adequate amount of material due to its magnetic pull, but this is also makes it easier to remove from the material after welding, compared with the larger sizes.
