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 equip- ment.

•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 1000 is critical to its operation. Generally speaking the calibration will not need adjustment. However, neglected or improperly calibrated machines may not yield satisfactory 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, use the calibration section of the Diagnostics Utility to make the appropriate adjustments.

The calibration procedure itself requires the use of a grid (Resistive Load Bank), and certified actual meters for voltage and current. The accuracy of the calibration will be directly affected by the accuracy of the measuring equipment you use. The Diagnostics Utility includes detailed instructions, and is available on the Power Wave Submerged Arc Utilities and Service Navigator CD’s.
