Using the GMAW Gun Anatomy knowledge point

The question asks for the component that routes the welding wire from the wire feeder to the contact tip through the MIG gun cable assembly.

• Liner: A flexible conduit (usually steel coil or Teflon) placed inside the gun cable that guides the wire smoothly from the feeder rolls to the contact tip.
• Contact Tip: Delivers the electrical current to the welding wire just before it exits the gun.
• Diffuser: Distributes the shielding gas evenly around the weld pool.
