<p>A control mechanism for a tungsten electrode (10) welding torch which allows a full length of tungsten (10) to be loaded and accurately fed to the welding torch. The control mechanism comprises an attachment means for attachment to the welding torch; a body portion having a throughbore, the body portion being connected to the attachment means; a tube moveable longitudinally within the bore of the body portion, the tube having an internal recess suitable to receive an electrode (10) for a welding torch, an end face at its far end relative to the attachment means, the end face suitable to abut with said electrode (10), preferably a sheath including said electrode (10), and the tube having an external thread mounted thereon. Benefits are that the electrode (10) may be accurately fed to the torch, and a full length of tungsten housed within the control mechanism and torch.</p> |
