Abstract: A welding electrode holder 10 comprises a body portion 12, a cable holding section 14, a cable collet 16 and an electrode clamping section 18. An electrical cable 20 from a power supply is held in the cable holding section 14 which is inserted into the body portion 12. An electrode 22 is inserted into an opening 24 in the body portion 12 and is clamped between the electrode clamping section 18 and a clamping head 26 of the cable holding section 14. Current is supplied to the cable 20 and is passed to the electrode via the cable holding section (which is electrically conducting) to the electrode 22 for welding to be carried out.
