FAQ

This current connection is designed specifically for Tweco #4 series MIG guns, including the classic Tweco 4 and potentially Spray Master 450 models utilizing the same backend architecture.

Yes, this is a genuine OEM part manufactured by ESAB (the parent company of Tweco), ensuring the highest quality and perfect fitment.

It is typically machined from high-conductivity brass or copper alloy to ensure efficient current transfer and resistance to heating.

Over time, electrical connections can wear, corrode, or loosen, causing resistance. This leads to heat buildup, voltage drop, and poor welding performance. Replacing it restores the gun's efficiency.

Installation involves disassembling the MIG gun handle or cable connection point, unthreading or unbolting the old connection, and securing the new one in place. Consult your specific gun's manual for a diagram.

If your unstable arc is caused by a poor internal electrical connection within the gun, replacing this part will likely solve the issue.
