The 2C332GS standard brass collet 3/32 (.094) from Weldmark® by CK Worldwide® is a brass, wedge style collet, compatible with both water and gas cooling methods. A collet is a mechanical clamping device, like a sleeve, that uses pressure and friction to hold an electrode in position within the welding torch. Collets are sized according to the diameter of the electrode used. In this case, it has a 3/32 (.094) electrode diameter, and narrow gas coverage. (Includes 5 per bag)
