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.
