Abstract

Clamping device (2) for clamping a non-consumable welding electrode (3) with an electrode holder (2A) which has a receiving chamber (2B) aligned in the longitudinal direction for receiving a welding electrode (3) which is insertable therein and at its front end has an end portion (2C) which widens conically towards the forward end and can be compressed by means of a clamping heat sink (2D) for holding the welding electrode (3), thus producing a large-surface cooling end face (KSF) for cooling the welding electrode (3).
