0193570109 - ESAB Eco-Arc II Replacement Adjustable Locking Arm

Genuine ESAB Replacement Locking Arm

The ESAB 0193570109 Adjustable Locking Arm is a critical component for maintaining the functionality of ESAB passive welding helmets, specifically the Eco-Arc II series. Designed as a direct OEM replacement, this part restores the headgear's ability to lock the helmet in the raised position, preventing accidental drops that can obstruct vision or cause annoyance during workflow. Manufactured from durable, high-impact plastic, it is engineered to withstand the repetitive stress of raising and lowering the hood thousands of times over its lifespan.

Over time, the friction mechanisms and locking arms on welding headgear can wear down due to constant use and exposure to workshop environments. This wear often results in a "floppy" helmet that refuses to stay up or falls too easily. Replacing the locking arm with this genuine ESAB part resolves these issues immediately, returning the helmet to its original factory specifications. The adjustable nature of the arm allows users to fine-tune the tension and positioning, ensuring maximum comfort and operational efficiency.

Installation is straightforward and requires no specialized tools, allowing welders to perform field repairs quickly and get back to work. By using genuine ESAB parts, you ensure that the tolerances match your existing headgear perfectly, avoiding the frustration of ill-fitting generic components. This locking arm is an essential spare part for any maintenance inventory supporting ESAB Eco-Arc II helmets.
