Output current (A) to be checked to ensure it falls within applicable ESAB Power Source specifications

Output Voltage (V) to be checked to ensure it falls within applicable ESAB Power Source specifications

Motor Speed (RPM) of wire drive motors to be checked to ensure it falls within required ESAB Power

Source / wire feeder specifications

Accuracy of digital meters to be checked to ensure it falls within applicable ESAB Power Source

specifications

Periodic calibration of other parameters such as timing functions are not required unless a specific fault has been identified.

C. Calibration Equipment

All equipment used for Power Source calibration shall be in proper working condition and be suitable for conducting the measure-

ment in question. Only test equipment with valid calibration certificates (NATA certified laboratories) shall be utilized.

5.03 Cleaning the Welding Power Source

To clean the Welding Power Source, open the enclosure and use a vacuum cleaner to remove any accumulated dirt, metal filings,

slag and loose material. Keep the shunt and lead screw surfaces clean as accumulated foreign material may reduce the welders

output welding current.

Clean the grooves in the drive rolls frequently. This can be done by using a small wire brush. Also wipe off, or clean the grooves on

the upper feed roll. After cleaning, tighten the feed roll retaining knobs.

CAUTION

Do NOT use compressed air to clean the Welding Power Source. Compressed air can force metal par-

ticles to lodge between live electrical parts and earthed metal parts within the Welding Power Source.

This may result in arcing between these parts and their eventual failure.
