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.
