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.

3.9 Installing Wire Rolls

To select the appropriate wire refer to Section 4.3 for guidance.
1. Open the left side panel (when facing the front of the welder)
2. Remove the Thumbscrew Spool Lock
3. Remove the Spring and the Spool Retainer
4. Place the Welding Wire Spool on the Spindle.
5. Load the wire as shown in the diagram on the following page.
6. Once the wire is in the feed position, close the side panel and turn on the
welder.
7. Use the MIG gun trigger to advance the wire through the torch until it
reaches a 1/4 to 3/8 stickout (electrode extending from the tip of the contact
tube.). (See Diagram 1 on the following page)
NOTE
ENSURE THAT POLARITY TERMINAL KNOBS ARE
TIGHTLY SECURED AND THAT THERE IS NO
CONNECTION BETWEEN POSITIVE AND NEGATIVE
TERMINALS.
