The Cool-Arc™ 40 is a reliable and affordable water cooler for water-cooled MIG or TIG
as well as plasma cutting applications. Available in both 115 and 230 volt models, the
Cool-Arc 40 is compatible with all Lincoln water-cooled systems including Cobramatic®.
The Cool-Arc 40 features a rugged industrial pump manufactured by Pro-Con®, the
leading pump manufacturer for welding water coolers. This pump is an industry standard,
making the Cool-Arc 40 easy to service and maintain. The Cool-Arc 40 operates smoothly
and minimizes vibrations that would otherwise be transferred to the welding torch.
