Each of the first and second portions may have a hole therethrough to enable an electrode to extend through the first and second portions. The first portion may be adapted to secure the welding torch member to a welding torch body. The first and second portions may have a hole therethrough to enable the electrode to extend through the welding torch member. The second portion may be adapted so that it may be compressed onto the electrode to secure the electrode to the welding torch. A second welding torch member may be urged against the first welding torch member to compress the second portion onto the electrode. The first and second welding torch members may be secured to a welding torch. A power source may be used to provide power to the electrode through the welding torch member.
