KP4159-1 - Lincoln Electric Low Conductivity Coolant for Cool Arc 47 - 1 Gallon

Protect Your Water-Cooled Gear

If you are running a water-cooled setup, specifically the Lincoln Cool Arc® 47 or Magnum® PRO series, using the right coolant isn't just a suggestion—it's a requirement for keeping your gear running. The Lincoln Electric KP4159-1 Low Conductivity Coolant is designed to keep your torch cool without frying your electronics. Many welders make the mistake of running distilled water or, worse, tap water in their coolers. While water cools well, it conducts electricity and breeds algae. Over time, this leads to clogged lines, burnt-out pumps, and the dreaded "torch failure" right in the middle of a job.

This coolant is formulated to have low electrical conductivity. Why does that matter? In a water-cooled TIG or MIG torch, the power cable often runs inside the water line to keep it cool. If your fluid conducts electricity, the current can leak out, causing electrolysis that eats away at your fittings and torch head from the inside out. Lincoln's KP4159-1 stops this process, protecting your investment and ensuring consistent arc performance. It also acts as a lubricant for the pump seals in your cooler, helping the motor run quieter and last longer.

Beyond electrical safety, this coolant handles the extremes of the shop environment. It won't freeze if you leave your rig in the truck overnight during winter, and it won't boil over during long, high-amperage welds. It also contains special additives to stop rust and mineral buildup. You don't need to mix it; just pour it straight from the 1-gallon jug into your reservoir. The white color makes it easy to see exactly how much fluid you have left in the tank, so you never run dry unexpectedly.

Usage Tips:

• Flush your old coolant completely before adding new fluid to avoid contamination.
• Check your coolant level weekly, especially during heavy use.
• Never add plain water to top off, as this dilutes the protective properties.
• Inspect hoses and fittings for leaks whenever you refill the tank.
