Figure 4-15 BackgroundAmperage control.
The PULSES PER SECOND control provides a means of selecting the pulse
selecting. Rotating the control clockwise increases the pulse frequency.
The scale is calibrated from 0.5 to 20 pulses per second.
IMPORTANT:
The
PULSES PER SECOND
control may be adjusted while welding.
RANGE SELECTION:
The PULSER CIRCUIT BOARD has an internal
jumper for selecting the desired range for the PUL-
SES PER SECOND control (J1 or J2), see figure.
For this unit J1 are not removed of position (range 0.5
to 20 pps).

IMPORTANT:
The
BACKGROUND AMPERAGE
control may be adjusted while welding.
The BACKGROUND AMPERAGE control provides a means of selecting the weld
output background amperage level. The BACKGROUND AMPERAGE is a percentage
of the peak amperage and can never be set to a value higher than the peak amperage.
Rotating the control clockwise increases the background amperage.
The scale is calibrated from 0 to 100 percent and should not be read as an amperage
or voltage.
