9SM16385-6 - Lincoln Electric M16385-6 Replacement Heat Exchanger Coil

Keep Your Torch Cool and Production Running

When you are pushing high amperage on a TIG or MIG job, your water cooler is the lifeline of your equipment. The Lincoln Electric Heat Exchanger is the heart of that cooling system, acting as the radiator that pulls heat out of the liquid so your torch stays cool in your hand. If you have noticed your torch getting uncomfortably hot, or if your cooler is leaking fluid, it might be time to replace the internal coil. This M16385-6 replacement part is the exact unit found in Cool Arc 40 coolers, designed to get your setup back to peak performance immediately.

A functioning heat exchanger is vital not just for comfort, but for the longevity of your consumables and cables. If the coolant isn't cooled effectively, the heat builds up in the power cable, eventually melting the liner or causing a blowout. By swapping out a damaged or clogged radiator with this new Lincoln unit, you ensure consistent flow and temperature control. This means you can weld longer at higher duty cycles without worrying about equipment failure. Don't let a burnt-out cooler stop your project; install the correct replacement part and keep the arc on.

Why Replace Your Heat Exchanger?

• Prevent Overheating: Stops the "hot hand" feeling during long welds.
• Protect Equipment: Saves expensive torches and cables from melting down.
• Restore Reliability: Eliminates leaks and pressure drops in your cooling loop.
