3-3. Overview And Controls Overview The control unit provides three modes of operation: CV Mig − control functions as a re- mote voltage control. Manual MIG Pulser − control func- tions as a discrete pulsed MIG CC control. Synergic Pulser − programs that use factory-entered values are used to control process.
3-4. Initial Display, Manual MIG Pulser Mode, And CV Mig Mode Software Number Defined Welding Power Source Type When power is applied, initial dis- play with software number and welding power source type appears momentarily, and then last program 304 model power source shown. to be viewed before control was shut down appears.
3-5. Setup Screens To access Setup screens: turn welding power source Off, press and hold Select push button, turn unit On, and hold push button down until initial screen leaves. To exit Setup screens, turn welding power source Off and then On again.
3-6. Choosing Pulse Programs And Setting Parameters Choosing Pulse Program: Pulse programs are pre-written and cannot be changed by the user. See Sections 4 and 6 for program parameters. Choose program depending on the type and size of wire, and type of shielding gas used. For example, the program shown below is for .045 steel wire using 95Ar −...
