WELDER/GENERATOR CONTROLS

See Figure B.1 for the location of the following fea-
tures:
1. OUTPUT RANGE SELECTOR: Selects continuous
current output for constant current stick or TIG
applications (blue settings) and constant voltage
wire feed applications (red settings). The amper-
ages on the dial correspond to the maximum
amperages for each corresponding range setting.
Never change the range switch setting while weld-
ing, since this could damage the switch.
2. FINE OUTPUT CONTROL: Allows fine adjustment
of current or voltage within the selected output
range.
