951195 - ESAB Water Cooler Pressure Relief Valve 100 PSI

Keep Your Cool with the Right Pressure

Your water cooler is the unsung hero of your welding rig, especially when you are pushing high amps on aluminum or running long beads on heavy steel. The ESAB 951195 Water Relief Regulator is the guardian of that system. Set to 100 PSI, this valve ensures that your expensive water-cooled TIG torch or MIG gun gets exactly the flow it needs without being subjected to dangerous pressure spikes that could blow out your hoses or ruin your torch head.

Think of this relief valve as the fuse for your water system. If you accidentally step on your water hose or roll a cart over it, pressure builds up instantly. Without this valve, that pressure has nowhere to go but out through the weakest point—usually your torch seals or the pump itself. This regulator detects that spike and instantly bypasses the water back to the tank, saving your gear from catastrophic failure. It also ensures that your pump isn't straining against a blockage, which keeps your motor running cooler and lasting longer.

Installation is straightforward, making it an easy fix for a cooler that isn't holding pressure correctly. If you notice your cooler is running but your torch is getting hot, or if you see the pressure gauge pinned at zero or maxed out, it might be time to swap out the relief valve. Using genuine ESAB parts like the 951195 guarantees that the fittings will match up perfectly and the pressure setting is exactly what the factory intended for your machine.

Don't let a small part cause a big headache. A failing regulator can lead to a burned-out torch power cable, which costs significantly more to replace than this valve. Keeping your cooling system in top shape means less downtime, cooler hands, and better welds. Whether you are maintaining a fleet of machines or just your personal rig, this 100 PSI regulator is essential for reliable, leak-free water cooling.
