0558003078 - ESAB Replacement Heat Exchanger Radiator 13x12x2.6

Precision Thermal Management for Industrial Welding

The ESAB 0558003078 Heat Exchanger is a specialized replacement component designed to restore the thermal efficiency of ESAB welding cooling systems. Measuring 13 inches by 12 inches with a depth of 2.6 inches, this radiator core is engineered to facilitate rapid heat transfer from the circulating coolant to the ambient air. In high-amperage TIG and MIG welding applications, the stability of the coolant temperature is paramount. As the coolant absorbs heat from the torch head and power cable, it must be effectively cooled before recirculating. This heat exchanger utilizes a high-density fin structure to maximize surface area, ensuring that the thermal load is dissipated efficiently even during high duty cycle operations.

Constructed to meet ESAB's rigorous OEM specifications, this unit ensures correct fitment within the machine chassis, aligning perfectly with existing fan shrouds and mounting points. The use of non-OEM radiators can often lead to airflow bypass or insufficient heat rejection, resulting in elevated coolant temperatures that can trigger thermal shutdowns or damage expensive torch components. This heat exchanger is built with materials selected for their resistance to corrosion and galvanic reaction, provided that the correct low-conductivity coolant is utilized in the system. It is an essential repair part for maintenance teams looking to extend the lifecycle of their welding power sources and water coolers.

Failure of a heat exchanger typically manifests as coolant leaks or a gradual inability to maintain safe operating temperatures. Physical damage to the fins from debris or impact can also reduce efficiency. Replacing a compromised unit with the ESAB 0558003078 restores the system to factory performance levels. This component is compatible with specific ESAB water cooling units and integrated cooling systems found in heavy-duty industrial power sources. Proper installation ensures leak-free operation and optimal pressure maintenance within the closed-loop system.

Industrial environments demand reliability. The robust construction of this heat exchanger is designed to withstand the vibration and thermal cycling inherent in welding operations. By maintaining the coolant at the optimal temperature, this component directly contributes to the consistency of the weld arc and the longevity of the welding gun or torch consumables. It is a critical investment in equipment uptime and process stability.
