3.8 Changing Between Processes

The MIG (GMAW) and Flux Core (FCAW) processes utilize different polarities


(DCEP and DCEN). To change between them follow these instructions:


  1. Make sure the machine is unplugged from the power receptacle.

  2. Open the door to the machine.

  3. Remove the polarity terminal knobs.

  4. Set up the polarity (as per graphics above) by removing the leads from the terminals and reversing them if necessary. Refer to Sections 3.6 and 3.7.

  5. Replace the polarity terminal knobs.




NOTE

ENSURE THAT POLARITY TERMINAL KNOBS ARE TIGHTLY SECURED AND THAT THERE IS NO CONNECTION BETWEEN POSITIVE AND NEGATIVE TERMINALS.
