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.

between live electrical parts and earthed metal parts within the Welding Power Source. This may result in arcing
between this parts and their eventual failure.5.05
