Industrial tools must stand up to a significant amount of abuse and continue to operate safely and reliably. For this reason LFT was selected as the material of choice to manufacture a handle/grip for a MIG welding machine.
These handles must stand up to being dropped, driven over by fork lifts and other forms of serious impact. On top of this it needs to be able to operate reliably and safely at elevated temperatures.
Generally speaking, with tools and equipment that have the ability to cause serious injury or even death, WH&S concerns require that parts must have a significant margin for error in terms of performance to ensure the safest possible working environment.
