Welding tip replacement apparatuses ; and method of replacing welding tip

摘要

A welding tip replacement apparatus (20) is used for a welding torch (10) that includes a tubular tip connection body, a tubular retaining member fitted over the tip connection body, and a tubular welding tip (1) fitted within the tip connection body, the welding torch (10) being configured such that displacing the retaining member toward the proximal end of the tip connection body along the axis of the tip connection body causes the welding tip (1) axially fastened to the tip connection body (3) to be released. The apparatus (20) includes a first grasping mechanism grasping the retaining member, a second grasping mechanism grasping the welding tip (1) protruding from the retaining member in a direction away from the distal end of the tip connection body, a first driving mechanism driving the first grasping mechanism axially, and a second driving mechanism driving the second grasping mechanism axially.
