PROBLEMS AND ROUTINE SERVICE 5-6 Manual 0-5423

5.04 Cleaning the Feed Rolls

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.
