KP52110-1 - Lincoln Electric HELIX C Series Low Profile TIG Back Cap

Genuine Lincoln Electric Orbital Consumable

The Lincoln Electric KP52110-1 HELIX® C Series Low Profile Back Cap is a specialized consumable component designed for the HELIX C Series orbital weld heads. In precision orbital TIG welding, the geometry of the weld head is critical, especially when operating in restricted environments such as pipe racks or complex assemblies. This back cap features a reduced height profile, significantly decreasing the overall radial footprint of the torch assembly.

Manufactured to Lincoln Electric's exacting standards, this back cap serves two primary functions: it applies the necessary pressure to the collet to secure the tungsten electrode, and it creates a hermetic seal at the back of the torch to maintain the integrity of the shielding gas coverage. A compromised seal can lead to porosity and tungsten contamination, making the quality of the back cap essential for code-quality welds.

The KP52110-1 is constructed from high-quality, heat-resistant materials capable of withstanding the thermal cycles inherent in continuous orbital welding operations. Its threaded interface is precision-machined to ensure smooth installation and removal, preventing cross-threading or seizing. This part is an essential spare for operators using the HELIX C clamp-on heads, ensuring that equipment downtime is minimized when working in tight access zones.
