Abstract
A welding electrode apparatus has a base member and a locking ring for clamping a consumable electrode tip to the electrode base. The base and the tip are predominantly made of copper, or a copper alloy. The base member has a first end that is threaded to fit a welding head that supplies electric current; and an electrically conductive second end to which the electrode tip is mounted. The second portion has an externally facing, axially extending cylindrical wall. A circumferential groove is formed in the wall. The locking ring has a quick-disconnect feature in the form of an array of spring-loaded detents that deflect to release the cylindrical wall of the first member, and that spring inwardly to seat in the circumferential groove.
Claims20
A welding electrode apparatus operable to capture a consumable welding electrode tip, said welding electrode apparatus comprising:
- a first member and a second member;
- said first member defining an electrode base;
- said second member being a locking ring;
- said electrode base having an electrically conductive seat;
- said electrode base having an indexing fitting;
- said locking ring having a retainer mounted to capture the consumable welding electrode tip next to, and in electrically conductive engagement with, said electrically conductive seat of said electrode base;
- and
- said locking ring having a dog, said dog being movable, said dog being spring-biased toward engagement with said indexing fitting;
- and
- said locking ring being operable to secure the consumable welding electrode tip to said electrode base in electrically conductive engagement therewith;
- said electrode base and said locking ring being mutually engageable;
- and
- said dog being displaceable to permit disengagement of said locking ring from said electrode base.
