Solid Bronze or Gun Metal Earth Clamp - 300 Amps
These high quality work return clamps will outlast many of the normal low cost crocodile type earth clamps. These thick section, solid metal jaw clamps, have a much higher current carrying capacity than the typical low cost pressed steel clamps, being produced from solid bronze / gun metal ensures these work return clamps provide the best continuity which means they will not generate heat due to a weak grip or poor conductivity.
These solid bronze work return clamps have a strong spring to provide the necessary strength of grip. This type of bronze is an alloy of 85% copper, 5% tin, 5% zinc & 5% lead which is why the material has a reddish apperance and is able to conduct power so well.
Named gun metal because this bronze alloy was orignally used to manufacture cannons due to the ability to cast guns without defects / blow holes it is also abrasion and corrosion resistant.
Another advantage of these clamps is the shape of the jaws which allows for quick and easy connection whilst remaining firm for continuity.
When you demand good welding results plus value for money these long lasting quality these work return clamps are what you need.
