COOLING EFFICIENCY

The high cooling efficiency of the COOL ARC® 40 offers a cooler, more comfortable Torch than a con- ventional air-cooled Torch.

The COOL ARC® 40 effectively removes the heat produced by the welding arc from the gun or torch handle and places it into the exiting air flow at the back of the Cooler. Ambient air temperature affects the effective coolant temperature of the COOL ARC® 40.

For example:

Unlike other water coolers that depend on bulky reser- voir size, the high efficiency components of the COOL ARC® 40 allows the reservoir to be small. The result is a lightweight, portable unit.
