USER INTERFACE PUSH BUTTON

The push button on the user interface of the cooler has two different functions:

Holding the push button in for 3 seconds toggles the cooler ON and OFF. When the cooler is turned OFF, the display will shown “oo”. In this condition, the cooler can only be turned ON again by pressing the push button for 3 seconds again, or by cycling input power to the power source. The power source has no control over the cooler when it is OFF. It begins com- municating with the cooler when the cooler is turned ON again. If the cooler is OFF when the power source is turned OFF, it will begin operation in the ON condi- tion when the power source is turned on again, and must be turned OFF if the user does not want the cooler to operate during welding.

Momentarily pressing the COOL ARC® 35 push but- ton will begin the torch priming procedure and over- ride any current cooler operation. The cooler will ramp up the pump speed to maximum and hold it for 30 seconds to allow the torch to be filled with coolant. During the priming procedure the temperature and flow/pressure sensing are disabled. To stop the prim- ing procedure before the 30 second time limit the push button must be pressed again - this places the cooler back into normal operating mode.
