SAFETY PRECAUTIONS
WARNING
ELECTRIC SHOCK can kill.
• Only Qualified personnel should perform this maintenance.
•Turn the input power OFF at the disconnect switch or fuse box before working on this equipment.
•Do not touch electrically hot parts.
ROUTINE MAINTENANCE
Routine maintenance consists of periodically blowing out the machine, using a low pressure airstream, to remove accumulated dust and dirt from the intake and outlet louvers, and the cool- ing channels in the machine.
PERIODIC MAINTENANCE
Calibration of the Power Wave AC/DC is critical to its operation. Generally speaking the calibration will not need adjustment. However, neglected or improperly calibrated machines may not yield sat- isfactory weld performance. To ensure optimal performance, the calibration of output Voltage and Current should be checked yearly.
CALIBRATION SPECIFICATION
Output Voltage and Current are calibrated at the factory. Generally speaking the machine calibration will not need adjustment. However, if the weld per- formance changes, or the yearly calibration check reveals a problem, contact the Lincoln Electric Company for the calibration software utility.
The calibration procedure itself requires the use of a grid, and certified actual meters for voltage and current. The accuracy of the calibration will be directly affected by the accuracy of the mea- suring equipment you use. Detailed instructions are available with the utility.
