NOTICE
A wire feeder (Figure 18) can be used when in the CV
mode. The wire feeder utilitizes the power output from
the DC welding terminals. Consult the manufacturer's
instructions when connecting the wire feeder to the
welder-generator.
SETUP
2. Select the appropriate welding wire size depending
on the application as referenced in the wire feeder
instruction manual.
3. After the correct wire size has been determined, install
wire spool onto wire feeder.
4. Adjust the CV voltage regulator for the desired DC
voltage to the wire feeder.
5. Reference Table 18 when using flux-cored wires
commonly known as Flux Cored Arc Welding (FCAW)
process. This process has two types of flux-cored
wires. One is self-shielded (FCAW-S), the other is
gas-shielded (FCAW-G).
