How To Install a Power Pin to a Tregaskiss MIG Gun
 

  1. Thread the power pin into the rear housing.
  2. Tighten the power pin into the rear housing using a 1-inch (2.54 cm) wrench on the rear housing and a 3/4-inch (19 mm) wrench on the power pin. Torque to 18 ft.-lbs. (24.4Nm).
  3. IMPORTANT: The thread-in two-piece power pin has a taper to seat and lock the power pin in the rear handle block. Tighten the power pin in the block with a wrench to ensure that the pin remains in place.
  4. Install the liner.
