57016100 - Arcair Protex Welding Coolant - 1 Gallon Case (Pack of 4)

Keep Your Torches Cool and Productive

Overheating is the enemy of welding productivity. When your liquid-cooled equipment runs hot, consumables wear out faster, duty cycles drop, and you risk catastrophic torch failure. Arcair Protex Coolant is the industry-standard solution for keeping your gear running cool. This 4-pack of 1-gallon bottles ensures you have an ample supply of high-quality coolant on hand for your shop's water coolers and recirculators.

Why not just use water?
Plain water, even distilled, lacks the lubrication and protective properties needed for industrial welding pumps. Over time, water promotes algae growth that clogs lines and causes corrosion that eats away at brass fittings. Automotive antifreeze is even worse; it contains stop-leak additives and silicates that can turn into a gel in welding pumps, destroying the seals. Arcair Protex is formulated specifically for welding. It flows freely, lubricates the pump to keep it quiet and efficient, and prevents the green slime of algae buildup.

All-Season Performance
Whether you are working in a hot fabrication shop or a drafty garage in the middle of winter, Protex has you covered. It resists freezing down to -30°F, so you don't have to worry about cracked pump housings or burst lines if the temperature drops. During operation, it efficiently pulls heat away from the torch head, allowing you to weld at higher amperages for longer periods without the handle getting too hot to hold.

Universal Compatibility
This coolant is safe for use with all standard liquid-cooled MIG, TIG, and Plasma systems. It is non-conductive, protecting your power cables and torch heads from internal arcing. Simply drain your old fluid, flush the system, and fill with Protex for instant protection and peace of mind.
