Suitcase 8RC/12RC portable wire feeders feature remote voltage control for MIG and flux-cored welding. The case is injection-molded, crush-proof and flame-retardant. The unit will replace the S22P12 feeder. Improvements include an inverted drive-roll mechanism, which makes it easier to insert wire, adjust drive-roll tension and access drive-assembly components for service. Weight ranges from 22 to 25.5 pounds. The feeders are covered by a three-year factory warranty.
