Abstract
A welding electrode unit includes a repositioning device that is movable. The repositioning device includes an energy storage device by way of which a welding electrode is connected directly or indirectly with the energy storage device can have a force applied to it for the purpose of a repositioning movement. The repositioning device is movable into a welding position by way of a forward movement and can be locked in the welding position.
Claims12
A welding electrode unit comprising:
- a repositioning device that is movable and includes a stored-energy means;
- and
- a welding electrode connected directly or indirectly to the stored-energy means such that the stored-energy means can apply a force to the welding electrode for purposes of a repositioning movement, wherein the repositioning device can be moved into a welding position by way of a forward movement and can be locked in the welding position, wherein the forward movement is movement of at least a portion of the welding electrode unit in a direction toward the workpiece;
- and
- further comprising a toggle lever mechanism for locking the repositioning device in the welding position.
2 more elements
A method for welding comprising:
- moving a welding electrode into a welding position by a forward movement, the forward movement being a direction toward a workpiece;
- locking a repositioning device connected to the welding electrode into the welding position;
- applying directly or indirectly a force to the welding electrode for a repositioning movement, and
- uncoupling said moving step from said applying step via a toggle lever mechanism.
