FRONT PANEL CONTROLS
The numbered items of Figure B.2 match the num- bered items described below:
These few instruments and controls are basic to the operation and monitoring of the Converter. They are intuitively laid out so that the panel left side is weld cur- rent related, and the right side is weld voltage related:
(1)Input Power/ Mode Switch has three positions:
Center is OFF, which shuts off input power to the Converter.
•Neither displays nor output is on if in OFF position.
Left is on for CC (constant current) welding mode.
•Only AMPS digital meter is lit, displaying the preset current setting.
•Output will be on at o.c.v. (open circuit voltage).
Right is on for CV (constant voltage) welding mode.
•Only VOLTS digital meter is lit, displaying the preset voltage setting.
•Output will be on at the output voltage setting.
(2)Output Control has
In CC mode it presets AMPS
In CV mode it presets VOLTS
(3)AMPS Digital Meter is a
Preset AMPS in CC mode when not welding. “Blank” in CV mode when not welding.
Actual AMPS while welding in both CC and CV modes.
