The utilized CuCrZr material is of outstanding importance in spot welding applications. This alloy offers the following advantages:
High Thermal Conductivity: Effectively dissipates the heat generated during welding, minimizing overheating and premature wear of the screw pin.
Excellent Mechanical Strength: Retains its strength even at high temperatures, ensuring the fastening remains tight under continuous load.
Excellent Hardness: Resists the wear caused by the vibration from screwing and the welding gun.
This screw pin is specifically for Electrode sets No. 7 and No. 9 optimized, and allows seamless integration with InvertaSpot welding systems.
The following accessories are also available for this product, which ensure the comprehensive maintenance and optimal operation of the system:
Description: O-rings for stud bolts, in a set of 3 (PU: 3 pcs.).
Function: These O-rings are essential for ensuring an effective seal at the connection point between the electrode holder and the C-Trafogun. The seal prevents dust, moisture, or contaminants from entering the critical mechanical joint, thus increasing the device's reliability in the long term.
Description: Special electrode holder.
Compatibility: Specifically designed for electrode sets number 7 and 9. This holder ensures the precise clamping and replacement of the electrode, which together with the stud bolt forms the complete fixing unit.
The reliability of welding equipment largely depends on the regular inspection and replacement of wear parts. The stud bolt 495693, as a moving and stressed element, can wear out or get damaged over time.
Recommended maintenance procedures:
Regular inspection: Before every welding operation, visually inspect the thread and head of the stud bolt for signs of damage, cracks, or excessive wear.
Seal replacement: Regular replacement of the O-rings (495694) is recommended to maintain sealing integrity, especially if the equipment is used in dusty or humid environments.
Pulling force: Adhering to the optimal tightening torque of the stud bolt is crucial. Under-tightening can lead to poor weld quality, while over-tightening can damage the threads or the electrode holder.
This stud bolt is an integral part of the Wieländer+Schill professional welding solutions, guaranteeing the precision and durability expected during auto body repair work.
