The reason why there are different shapes of fixed multi angle weld clamp magnets is because they can all create a different amount of angles.
6-sided fixed multi angle weld clamp magnets
This variety of fixed multi angle weld clamp magnet has 6 sides and is in the shape of an irregular hexagon.
This magnet can be used to create the angles 30°, 45°, 60°, 75°, and 90°.
Magnetic square fixed multi angle weld clamp magnets
A magnetic square fixed multi angle weld clamp magnet always has a 90° corner, but can come with a varying number of extra corners to create different angles. It is always in the shape of a right angle triangle.
Magnetic squares can achieve 30°, 45°, 60° and 90° angles depending the number of extra corners they have e.g. some varieties of magnetic squares can only make 90° and 45° angles, whereas others can create 90°, 30°, 45° and 60° angles.
Arrow fixed multi angle weld clamp magnets
An arrow fixed multi angle weld clamp magnet has 8 sides and is in the shape of a blunt arrow.
Arrow magnets can be used to create 45°, 90° and 135° angles.
Corner fixed multi angle weld clamp magnets
This variety of fixed multi angle weld clamp magnet is always in an L-shape . It is used to create inside and outside corners of steel shapes.
It can create the angles 60°, 90° and 120°.
The best variety of fixed multi angle weld clamp magnet for overall use would be the 6-sided fixed multi angle. This is because this variety has the largest amount of angles available so has a wider range of uses within the welding industry.
