Item Details

  • The Miller / Bernard LAD3A-15 is a 15-foot front-loading MIG welding liner assembly engineered for the AccuLock™ S consumable system. It establishes a continuous wire-feed path to minimize wire-feed malfunctions such as bird-nesting and arc instability by ensuring concentric alignment between the power pin and the contact tip.

Features

  • Front-load design: Allows liner replacement from the front of the gun without removing the torch from the wire feeder
  • Front-locking mechanism: Secures the liner at the front and requires trimming flush with the power pin at the rear
  • Concentric alignment: Liner lock aligns the conduit with the contact tip and power pin to reduce wire drag
  • Consumable Longevity: Reduces friction and burnbacks to extend contact tip service life by 2–3x
  • Mechanical Integrity: Monocoil construction provides flexibility and prevents kinking during wire transition
  • Measurement-Free Installation: Eliminates the need for precise manual measurements during trimming
