To prevent damage and problem of the welding power source and loss of the data, ensure to follow the
instructions below:
• The welding conditions (electronic data) stored by this function are susceptible to
occurrence of static electricity, impact, repair, etc., and there is a possibility that the
stored contents may be changed or lost. Important information should also be stored
as printed document.
Please note that OTC will not be liable for any alteration or loss of electronic
information.
• When cleaning the welding power source, do not expose the cooling fan directly to
compressed air.
Otherwise powder dust may get inside the cooling fan. Also the cooling fan may rotate
at high speed due to compressed air, resulting in wearing of the bearing.
• When using a vacuum cleaner to remove powder dust accumulating on the welding
power source, do not vacuum between the rotating part of cooling fan and the main
body.
Otherwise lubricant of the bearing of cooling fan may also be removed, resulting in
failure or shorter service life of the cooling fan.
