0558003078 - ESAB Replacement Heat Exchanger Radiator 13x12x2.6

Keep Your Cool Under Pressure

When your water cooler stops doing its job, your welding stops too. The ESAB 0558003078 Heat Exchanger is the direct replacement radiator you need to get your cooling system back in fighting shape. If you've noticed your TIG torch getting uncomfortably hot, your coolant temperature warning light flickering on, or a puddle of fluid forming under your machine, a clogged or leaking heat exchanger is often the culprit. This unit measures 13" x 12" x 2.6" and is designed to drop right into your existing ESAB equipment without the headache of modifying mounts or rerouting hoses.

Think of this heat exchanger like the radiator in your truck. Its job is to take the hot coolant coming back from your torch and chill it down before sending it back out. Over time, the fins can get clogged with shop dust, or the internal tubes can corrode or crack. When that happens, your torch runs hot, your consumables burn up faster, and you risk blowing out your power cable. Swapping in this brand-new, genuine ESAB core ensures you get maximum airflow and heat removal, so you can run high amps all day without overheating.

Don't risk your expensive water-cooled torch on a radiator that's seen better days. This replacement part is built tough to handle the vibration of a busy shop and the pressure of a high-performance pump. It features a dense fin design that grabs as much air as possible from your cooling fan, rapidly dropping the fluid temperature. Whether you are running a heavy-duty MIG setup or precision TIG, consistent cooling is the key to consistent welds. If your cooler is struggling to keep up, this heat exchanger is the fix.

Installation is straightforward for those familiar with equipment repair. Simply drain your old coolant, disconnect the lines, unbolt the old unit, and swap this one in. Make sure to refill with fresh, high-quality welding coolant to protect your new investment. Don't let a $500 torch burn up because of a bad radiator—replace it with the ESAB 0558003078 and keep your arc on and your equipment safe.
