0152773880 - ESAB PKB 250/400 Swan Neck Conductor Tube

Restore Precision to Your PKB Torch

If you are experiencing erratic arc performance or inconsistent wire feeding with your ESAB PKB 250 or PKB 400 MIG gun, the issue might lie within the torch neck. The ESAB Connecting Tube (0152773880) is the direct replacement conductor tube you need to get your torch back in fighting shape. Over time, the internal surface of the connecting tube can become worn or clogged with debris, and the tube itself can sustain damage from heat or drops. Replacing this core component is often the most effective way to troubleshoot feeding issues and restore the smooth, stable arc you rely on for quality welds.

This connecting tube acts as the main highway for both your welding current and your shielding gas. A compromised tube can lead to voltage drops, causing the arc to stutter, or gas turbulence that results in porosity. By installing a fresh, genuine ESAB connecting tube, you ensure that the maximum amount of current reaches the contact tip and that your gas coverage remains laminar and effective. The part is designed for a perfect fit, making the swap-out process straightforward—simply disassemble the front end of your PKB torch, replace the old tube, and reassemble. No modifications or guesswork required.

Welders know that the "feel" of the gun depends heavily on the condition of the neck. A bent or damaged connecting tube can increase friction on the wire liner, leading to bird-nesting at the feeder or surging at the tip. This OEM replacement restores the original geometry of the torch, ensuring that the wire glides through effortlessly. Whether you are welding mild steel, aluminum, or stainless, maintaining the integrity of your torch's conductor path is essential for producing professional-grade beads. Keep your PKB torch running like new with this essential replacement part.
