W4001400 - ESAB Premium Welding Coolant for MIG & TIG Systems (5L / 1.3 Gal)

Keep Your Equipment Running Cool

Heat is the enemy of your welding gear. Whether you are pushing high amps on a TIG aluminum job or running long beads with a water-cooled MIG gun, your cooling system is the lifeline of your torch. ESAB W4001400 Welding Coolant is the premium choice for keeping that system running smoothly. Designed to replace plain water or inferior coolants, this 5-liter jug provides everything your water cooler needs to protect your investment.

Why Not Just Use Water?

Using tap water or even distilled water alone can lead to big problems over time. Water allows algae to grow, which turns into a sludge that clogs your lines and burns out your pump. It also freezes if your shop gets cold in the winter, potentially cracking your radiator or pump housing. ESAB's coolant contains special inhibitors that stop algae dead in its tracks and prevent freezing, ensuring your cooler is ready to work whenever you are.

Protect Your Torch

Automotive antifreeze is great for cars but terrible for welders because it conducts electricity. If you use it in a TIG torch, the high-frequency start can short out through the fluid, ruining your torch head and cables. ESAB W4001400 is a low-conductivity formula, meaning it keeps the electricity at the arc where it belongs, not in your cooling lines. It also lubricates the seals in your pump, making them last longer and run quieter. Simply pour it in—no mixing required—and get back to welding with confidence.
