OVERVIEW

Keep Your Cool with the Thermal Dynamics 9-5941 Radiator

Heat is the enemy of any high-amperage welding or plasma cutting operation. Your water cooler is the heart of your thermal management system, and the radiator is its lungs. The Thermal Dynamics 9-5941 Radiator is the direct replacement you need when your cooling system starts to lose its edge. Whether your old radiator has sprung a leak, become hopelessly clogged with shop dust, or suffered impact damage, swapping it out is the only way to ensure your expensive torch doesn't melt down in the middle of a job.

Designed specifically for Thermal Dynamics cooling units, this 9" x 9" heat exchanger fits perfectly into the chassis without the need for retrofitting or "making it work." It comes with the correct 3/8" tube connections, so you can hook up your coolant lines securely and get back to work fast. A healthy radiator means your coolant stays at the right temperature, which translates to consistent arc quality, longer consumable life, and less downtime for your shop.

Why Replace Your Radiator?

  • Prevent Overheating: If your coolant light keeps coming on or your torch feels hotter than usual, a clogged radiator might be the culprit.
  • Fix Leaks: Coolant on the floor is a safety hazard and a sign your system is losing pressure. A new radiator solves structural leaks instantly.
  • Protect Your Investment: A few hundred dollars in cooling maintenance can save you thousands in torch and cable replacements.

Built for the Shop Environment

Industrial environments are tough on equipment. Dust, metal shavings, and grime can coat radiator fins, acting as an insulating blanket that traps heat. While cleaning helps, eventually, corrosion or physical damage necessitates a replacement. This OEM part is built to the same rugged standards as your original machine, ensuring it can handle the vibration and thermal cycles of daily use. Don't risk your production schedule on a failing cooling system—restore your cooler's performance with the 9-5941.

FAQ

The radiator core measures 9 inches by 9 inches.

It features 3/8-inch tubing for coolant connections.

Yes, this is a genuine Thermal Dynamics (ESAB) replacement part.

Signs include visible coolant leaks, physical damage to the fins that blocks airflow, or persistent overheating of the torch despite the pump working correctly.

While some radiator shops can repair minor leaks, it is often more cost-effective and reliable to replace the unit, especially if the core is corroded or heavily clogged.

No, this item is the radiator (heat exchanger) only. The fan is a separate component within the cooling unit.

Always use the coolant specified by the manufacturer for your specific water cooler model (usually a specific glycol/water mix) to prevent corrosion and freezing.

It is designed specifically for Thermal Dynamics units. While it may physically fit others with 9x9 space and 3/8" lines, compatibility is not guaranteed for non-TD equipment.
