0558011991 - ESAB Coolant Level Switch with Terminals

Protect Your Welding Investment with Genuine ESAB Parts

The ESAB 0558011991 Coolant Level Switch is a critical component designed to safeguard your water-cooled welding systems. In high-amperage TIG and MIG welding applications, maintaining proper coolant flow is essential to prevent catastrophic failure of the welding torch and power cable. This specialized level switch actively monitors the fluid volume within your cooling unit's reservoir, serving as a primary line of defense against dry-running pumps and overheated equipment.

Engineered specifically for ESAB cooling units, this OEM part ensures precise compatibility and reliable operation. Unlike generic sensors that may have incorrect float buoyancy or electrical ratings, the 0558011991 is built to ESAB's exact specifications. It features integrated terminals ("W/TERM"), streamlining the installation process by eliminating the need for additional crimping or soldering during replacement. When the coolant level drops below a safe threshold, this switch triggers the system's safety interlock, preventing the power source from operating until the fluid is replenished.

Regular maintenance of your cooling system's sensors is vital for industrial reliability. A faulty level switch can lead to false alarms that halt production or, worse, fail to detect a low-water condition, leading to expensive equipment repairs. By choosing this genuine ESAB replacement, you ensure that your welding cell remains operational, safe, and efficient. Whether you are repairing a standalone water cooler or an integrated cooling system within a power source, this switch provides the durability and accuracy required for professional environments.
