OVERVIEW

Optimize Your Wire Feeding with Genuine ESAB Parts

The ESAB 19166 Liner is a critical replacement component designed specifically for the ST-23A series of MIG guns. In the world of semi-automatic welding, the liner acts as the conduit for the welding wire, guiding it from the feeder through the cable assembly to the contact tip. Over time, liners can become clogged with copper shavings, dirt, and debris, or physically worn down by the constant friction of the moving wire. This degradation often leads to erratic wire feeding, arc instability, and increased downtime. Installing a fresh, high-quality liner like the ESAB 19166 is essential for maintaining the precision and reliability of your welding operations.

Engineered to accommodate 0.030-inch and 0.035-inch diameter wires, this liner provides the exact internal clearance necessary to support the wire without causing excessive drag or allowing the wire to buckle (bird-nest) inside the cable. The steel wound construction offers excellent flexibility while maintaining the structural rigidity needed to prevent kinking when the gun cable is bent during operation. This balance is crucial for welders who move frequently around large workpieces and require consistent performance regardless of the torch angle.

At Josef Gas, we understand that using genuine OEM parts is key to equipment longevity. The ESAB 19166 is manufactured to the original specifications of the ST-23A torch, ensuring a seamless fit at both the back-end connection and the diffuser end. This precise fitment prevents gas leaks and ensures that the shielding gas is delivered effectively to the weld pool. Whether you are fabricating mild steel structures or performing automotive repairs, ensuring your wire delivery system is in top condition is the first step toward achieving X-ray quality welds.

Key Technical Benefits

  • Reduced Friction: Smooth internal surface minimizes drag on the wire, reducing strain on the drive rolls and motor.
  • Precise Fit: Designed exclusively for the ST-23A platform, eliminating the need for modifications.
  • Durability: High-tensile steel coil resists wear from hard wires and rough handling.

FAQ

This liner is designed for use with 0.030-inch (0.8mm) and 0.035-inch (0.9mm) welding wires.

No, this is a steel wound liner intended for hard wires (steel, stainless steel). For aluminum welding, a Teflon or polymer liner is recommended to prevent shaving the soft wire.

The ESAB 19166 is specifically designed for the ST-23A series MIG guns.

Signs of a worn liner include erratic wire feeding, the wire slipping at the drive rolls, bird-nesting, or excessive debris seen when the wire is removed.

Yes, liners often need to be trimmed to the exact length of your specific cable assembly. Always follow the manufacturer's instructions for trimming and fitting.

Yes, this is a genuine ESAB replacement part, ensuring proper fit and performance with your ESAB equipment.
