Abstract: At 5:00 a.m. on January 7, 2022, an employee was running feed wire through a Lincoln Power Wave Wire Feeder drive wheel with his right hand, while pressing the trigger of the Mig Gun positioned in the left hand. The trigger acts as a power button and allows the wire to process through the feeder to the Mig Gun for welding processes. The employee was wearing a fire resistant welder shield, welding gloves/apron, and safety glasses at the time and normally works a normal 8 hour schedule (5:30 a.m. to 3:30 p.m.), although hours vary depending on daily work load. The cover for the drive wheel was off, due to the wire being dislodged in the wheels. The employee caught the sleeve of his jacket in the drive wheels as a result causing his hand to be pulled into the machine. The employee crushed his right thumb tip, which later was amputated and required medical treatment without hospitalization.
