7977981 - Thermal Arc Wire Feed Motor Assembly 7977981

Genuine ESAB Thermal Arc Wire Drive Motor (7977981)

The ESAB Thermal Arc 7977981 Wire Drive Motor is a critical replacement component designed for specific Thermal Arc MIG welding power sources. As the heart of the wire feeding system, this motor is responsible for pulling welding wire from the spool and pushing it through the liner to the contact tip at a consistent, user-defined speed. When a wire drive motor begins to fail, it can manifest as erratic wire feeding, speed fluctuations that do not match the dial setting, or a complete cessation of wire movement. Replacing a faulty motor with this genuine OEM part ensures that the machine operates within its original factory specifications.

This assembly is engineered to meet the precise voltage and torque requirements of Thermal Arc Fabricator series and compatible machines. Using non-OEM motors can lead to control board damage or inconsistent arc characteristics due to incorrect impedance or speed curves. The 7977981 motor assembly is built to withstand the rigors of industrial welding environments, providing the torque necessary to push wire through standard torch lengths without slipping or stalling, provided the liner and drive rolls are in good condition.

Maintenance professionals and equipment repair technicians rely on genuine ESAB parts to guarantee repair longevity. This unit is a direct-fit replacement, meaning mounting points and electrical connections are designed to match the original equipment configuration, reducing bench time and simplifying the repair process. Whether performing a preventative maintenance overhaul or an emergency repair, this wire drive motor is the correct specification for restoring the wire feed system to optimal functionality.
