COOLING EFFICIENCY
The high cooling efficiency of the COOL ARC ® 40
offers a cooler, more comfortable weld than conven-
tional air-cooled procedures as well as leading com-
petitors water cooled systems.
The COOL ARC ® 40 effectively removes the heat of
the arc away 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 coolant tempera-
ture 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 size to be small. The
result is a lightweight, portable unit.
