The water cooler does not turn on.

1. Make sure that the water cooler has been

 

 

 

 

enabled. Refer to the Setup Overlay descrip-

 

 

 

 

 

 

 

 

 

 

tion in the Operation Section of this manual.

on the machine. In this case do the following:

 

 

 

 

 

1. Turn the machine off and on a couple of

 

 

 

 

 

times and see if the beeping continues. If the

 

 

 

 

 

pressure dropped momentarily then turning

 

 

 

 

 

the machine off and on eliminates the beep-

 

 

 

 

 

ing. A momentary pressure drop could be due

 

 

 

 

 

to someone stepping on the water cooler

 

 

 

 

 

hose, for example.

 

 

 

 

 

2 Check the water cooler hose for kinks and

 

 

 

 

 

other places of reduced water flow. If such

 

 

 

 

 

problems were found then correct them and

 

 

 

 

 

turn the machine off and on to check if the

 

 

 

 

 

beeping has been eliminated.

 

 

 

 

 

3. Check the water cooler fluid level. Low fluid

 

 

 

 

 

level could cause the pressure to drop.

 

 

 

 

 

4. Prime the water cooler. Refer to the Setup

 

 

 

 

 

Overlay section of this manual for instructions.

 

 

 

 

 

 

 

 

 

CAUTION

If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, con- tact your local authorized Lincoln Electric Field Service Facility for technical assistance.
