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.

Take the nipple and the connector nut ordered above and insert the nipple into the connector nut so that the threaded end of the connector nut points away from the barbed end of the nipple. Twist the barbed end of the nipple into the hose until the shoulder of the nip- ple is flush with the end of the hose. Secure the hose onto the nipple with the hose clamp to insure that the connection is watertight. No water can leak from the connection if it is properly attached. Repeat the proce- dure for the OUTLET hose.
