2200311 - Bernard Set Screw for LAD3A-15 Lincoln Power Pin Adapter

Authentic Bernard Replacement Hardware

Maintain the integrity of your welding setup with the Bernard 2200311 Set Screw. This replacement part is essential for welders using Bernard Q-Gun, S-Gun, or T-Gun series MIG guns configured with the LAD3A-15 adapter for Lincoln Electric wire feeders. The power pin adapter is the lifeline of your welding system, transferring current, shielding gas, and control signals. This set screw ensures that the protective cap and internal components of the adapter stay rigidly in place.

Over time, set screws can become lost during disassembly for liner changes or rounded out due to the use of improper tools. Replacing them with the correct Bernard 2200311 screw restores the mechanical security of the gun connection. A loose power pin cap can lead to gas leaks at the feeder, poor electrical contact, and eventual overheating of the power pin, which can cause expensive damage to both the gun and the feeder drive rolls.

This item is a direct OEM replacement, ensuring it meets the exact dimensional tolerances required by Bernard's engineering standards. It is a small but indispensable part of your spare parts inventory. Installation is straightforward, requiring only a standard hex key. Ensure your Lincoln-connected Bernard guns are ready for heavy-duty fabrication by inspecting and replacing worn hardware regularly.

Application

Intended for use solely with the Bernard LAD3A-15 Power Pin, commonly identified by its compatibility with Lincoln feeders and often associated with white color-coding on the strain relief or cap assembly.
