Lincoln Cool Arc 40 115V Welding Water Cooler

Maximize Torch Life with the Lincoln Cool Arc 40

Keep your welding equipment running at peak performance with the Lincoln Cool Arc 40 Water Cooler. This 115V cooling system is a must-have addition for professional fabricators using water-cooled MIG, TIG, or plasma cutting setups. Heat is the enemy of welding consumables and torch cables; the Cool Arc 40 combats this with a high-efficiency cooling loop driven by a premium Pro-Con pump. This pump is designed for continuous industrial operation, delivering the steady pressure required to prevent torch overheating, which can lead to costly downtime and premature equipment failure.

Advantage Lincoln: Designed for the Shop Floor

Lincoln Electric has designed the Cool Arc 40 with the realities of the welding shop in mind. Space is often at a premium, which is why this unit features a unique multi-position design. You can mount and operate the cooler either vertically or horizontally, giving you the flexibility to fit it onto a crowded welding cart or tuck it into a tight workspace without sacrificing performance. The unit is also surprisingly lightweight, thanks to its 2-gallon non-corrosive plastic reservoir. This tank not only reduces the overall weight to just 60 lbs when full but also ensures that rust will never be an issue, keeping your coolant lines clean and free of debris.

Quiet and Smooth Operation

Noise and vibration can be significant distractions during precision welding. The Cool Arc 40 addresses this with a specially designed "muffin-style" tube axial fan. This component moves a high volume of air through the heat exchanger while maintaining low noise levels. More importantly, it operates smoothly to minimize vibration. Excessive vibration from auxiliary equipment can sometimes transfer through cables to the torch, affecting hand stability; the Cool Arc 40 eliminates this variable, helping you maintain a steady hand and a clean bead.

Setup is hassle-free with color-coded inlet and outlet connections that utilize standard CGA-style fittings (5/8-18 left-hand thread). Whether you are running a standard TIG torch or a heavy-duty Cobramatic push-pull MIG gun, this cooler provides the thermal management you need. For most indoor applications, simple tap water is all that is required, making this an affordable and low-maintenance solution for your water-cooled welding needs.
