Maintenance 

 

 WARNING 

For any repair operations, modifications or maintenances, 
it is recommended to contact the nearest Technical 
Service Center or Lincoln Electric. Repairs and 
modifications performed by unauthorized service or 
personnel will cause, that the manufacturer’s warranty will 
become null and void. 
 
Any noticeable damage should be reported immediately 
and repaired. 
 

Routine maintenance (everyday) 

  Check condition of water-cooler hoses, connections of 

the power lead. 

  Check the welding torch / gun condition: replace it, if 

necessary. 

  Check condition and operation of the cooling fan. 

Keep clean its airflow slots. 

  The reservoir volume should be checked daily before 

using the cooler!! 

  Keep the reservoir full, especially after disconnecting 

the water lines or changing the accessory being 
cooled. 

 

Periodic maintenance (not less than once a year) 

Perform the routine maintenance and, in addition: 

  Keep the machine clean. Using a dry (and low 

pressure) airflow, remove the dust from the external 
case and from the cabinet inside. 

  In dirty or dusty environments or if biological growth 

occurs in the coolant, it may be necessary to flush the 
coolant reservoir. Drain the old coolant, rinse the 
inside of the reservoir and circulate rinsing solution 
through the coolant system. Add new coolant when 
cleaning is finished. 

 

 WARNING 

Hot coolant can burn skin. Always be sure coolant is NOT 
HOT before servicing the cooler. 
 

 WARNING 

 

Special precautions have to be taken when 
the coolant is removed from the cooler 
reservoir. The coolant must not be poured 
out into ground water, sewerage, soil. Read 
"Material Safety Data Sheet" (coolant used) 
and contact the local Department of 
Environmental Protection office to obtain 
information on recycling coolant. 

 
The frequency of the maintenance operations may vary in 
accordance with the working environment where the 
machine is placed. 

 WARNING 

Do not touch electrically live parts. 
 

 WARNING 

Before the case of machine will be removed, the machine 
had to be turned off and the power lead had to be 
disconnected from mains socket. 
 

 WARNING 

Mains supply network must be disconnected from the 
machine before each maintenance and service. After 
each repair, perform proper tests to ensure safety.
