There are four different types of weld clamp magnet: multi angle, adjustable links, variable angle, and 90 degree angle.
 
These can all come in a wide variety of different shapes and sizes, but their basic characteristics stay the same.
 

      
Adjustable links weld clamp magnets

Adjustable links weld clamp magnets can be adjusted from 0 to 360 degrees. The angles are adjusted by two wing nuts on each magnet. This allows the magnets to be moved individually.
 

      
Fixed multi angle weld clamp magnets

Fixed multi angle magnets can be set to angles ranging from 30 to 180 degrees. These angles can be achieved by turning the magnet onto its different sides.
 
This is because each corner on a fixed multi angle weld clamp magnet is set at a different angle.
 

      
Variable angle weld clamp magnets

A variable angle weld clamp magnet consists of two magnets held together on a pivot bolt.
 
They can be adjusted to angles varying from 22 to 275 degrees by moving the magnets around the pivot bolt until the required angle is achieved.
 

      
90 degree angle weld clamp magnets

A 90 degree angle weld clamp magnet is made of two block magnets set at a fixed 90 degree angle.
