The Multiquip MQ17720 Liner 5/64" 3/32" 12FT is a genuine OEM wire feed liner designed for the MT400CCEHD. This 12-foot liner is manufactured to exact OEM specifications, ensuring the wire feed path remains clean, unobstructed, and properly guided from the drive rolls to the welding gun tip. Compatible with both 5/64" and 3/32" wire diameters, MQ17720 delivers consistent wire feeding performance critical to maintaining clean, stable arc welding output on the MT400CCEHD.
Key Features
- Genuine OEM Wire Path Integrity — Manufactured to the exact interior diameter tolerances required for smooth, kink-free wire travel through the full 12-foot liner length.
- Dual Wire Diameter Compatibility — Accepts both 5/64" and 3/32" wire, giving operators flexibility across multiple wire types without swapping liners.
- Direct-Fit for MT400CCEHD — Engineered specifically for the MT400CCEHD, replacing the original liner without any trimming or modification to the feed assembly.
- Consistent Arc Stability — A properly functioning liner maintains even wire feed speed, which directly controls arc consistency and weld bead quality; a worn or clogged liner causes erratic feeding and arc interruptions.
- Fuel System Cleanliness Compliance — Clean liner internals prevent wire shavings and debris from contaminating the contact tip and gun, extending the service life of downstream welding consumables.
A wire feed liner is the conduit that guides the welding wire from the wire drive mechanism through the gun cable and out to the contact tip. When the liner is in good condition, wire travels smoothly and at a consistent rate, producing a stable arc and clean welds. As a liner wears, accumulates debris, or develops kinks, the wire begins to bird-nest, stutter, or feed unevenly — causing arc instability, burn-back, and increased contact tip failures. Replacing the liner with a genuine Multiquip MQ17720 restores proper wire travel and protects the rest of the welding consumable system.
