The Lincoln Electric T14813 Thumb Screw is a critical hardware component for the wire drive systems of many Lincoln MIG welders. Located on the wire drive assembly inside the machine, this screw applies pressure to the brass backend of the MIG gun, locking it into the feeder block. Without this screw properly tightened, the MIG gun can slide out of position, breaking the electrical circuit or causing a misalignment that disrupts the feeding of the welding wire. This OEM replacement part restores the functionality of your machine's gun retention system immediately.
Designed for durability and ease of use, the T14813 utilizes a rugged plastic head with a textured grip surface, allowing welders to tighten the screw firmly by hand. This tool-free operation is essential for quick changeovers in the shop. The threaded portion is manufactured from high-grade steel to resist cross-threading and wear, ensuring a long service life even with repeated use. If your current screw is cracked, missing, or the threads are damaged, it can compromise the quality of your welds by allowing the gun to wobble or lose connection with the power pin.
This part is widely used across the Lincoln Electric product line, particularly on compact, portable MIG machines. It fits the casting of the wire drive assembly found in many 110V and 220V units. Installing this screw is a matter of seconds, but its role is fundamental to the welding process. A loose gun connection is a common, often overlooked cause of poor arc starts and porosity. Ensure your equipment runs smoothly by replacing damaged hardware with the correct OEM part.
