OVERVIEW

Genuine ESAB Replacement Jumper Liner for ST-16 Systems

The ESAB 636879 Liner ST-16 Jumper S 1/16 is a critical replacement component designed for the maintenance of ESAB ST-16 MIG welding guns. In industrial welding environments, the integrity of the wire feed path is paramount to maintaining production efficiency and weld quality. This specific "jumper" liner is engineered to bridge the gap within the gun's internal assembly, ensuring that 1/16-inch (1.6mm) welding wire transitions smoothly from the main conduit into the contact tip or through intermediate feed sections. As an OEM part, it guarantees precise dimensional fit and material compatibility with existing ESAB equipment.

Wear and tear on liners is a leading cause of wire feeding issues, including erratic arc starts, burn-backs, and increased spatter. The ST-16 Jumper Liner is manufactured to strict tolerances to minimize friction and prevent the shaving of wire coatings, which can clog liners and degrade performance over time. For procurement managers and facility maintenance teams, stocking genuine ESAB consumables like the 636879 ensures that downtime is minimized during scheduled maintenance or unexpected repairs. This liner is specifically rated for heavy-duty 1/16" wire applications, often found in structural steel and heavy fabrication sectors.

Investing in authentic ESAB parts protects the longevity of the entire torch assembly. Generic alternatives may not possess the correct coil pitch or internal diameter required for the ST-16's specific geometry, leading to premature failure. This jumper liner provides the reliability professional operations demand, ensuring that the welding parameters set at the power source are accurately delivered to the workpiece without mechanical interference in the feed system.

Key Technical Benefits:

  • Precision Fit: Engineered exclusively for the ST-16 platform to eliminate misalignment.
  • Optimized Flow: Internal surface finish reduces drag on 1/16" solid and flux-cored wires.
  • Durability: Resists heat and abrasion common in high-amperage welding environments.

FAQ

This liner is designed specifically for 1/16-inch (1.6mm) welding wire.

No, this is a "Jumper" liner, which is typically a shorter liner segment used to bridge specific sections within the torch or feeder assembly.

This part is compatible with the ESAB / L-Tec ST-16 MIG gun.

If you experience erratic wire feeding, slipping drive rolls, or arc instability despite having a good contact tip, the liner may be worn or clogged.

It is not recommended. Using a liner with an internal diameter meant for 1/16" wire with smaller wires can cause the wire to wander inside the liner, leading to poor electrical contact and erratic feeding.

Yes, this is a genuine ESAB replacement part, ensuring correct specifications for the ST-16 torch.

While not explicitly specified in the short data, standard liners for steel wire are typically made of wound steel spring wire. If welding aluminum, a polymer liner would be required, but this part number is generally associated with steel applications.

This SKU typically includes the liner itself. Check the 'Includes' section or product packaging for any small accessories, but usually, retention hardware is sold separately.
