1 % On Time Control
Use this control as a way of select-
ing pulse width (peak amperage
output time of one pulse). The scale
surrounding the control ranges
from 5 to 95 percent.
Pulser switch (see Section 4-10)

must be in the On position.
This control can be
adjusted while welding.
1 Amperage Switch
Use switch to select way of control-
ling amperage adjustment.
For front panel control, place switch
in Panel position. The Peak and
Background Amperage controls
will control the available amperage.
For remote control, make connec-
tions to the Remote 14 receptacle
(see Section 3-4), and place switch
in Remote 14 position. When a re-
mote amperage control is used and
the Pulser switch (see Section
4-10) is in the On position, the peak
and background amperage will
change proportionately with the
setting on the remote amperage
control. When the Pulser switch is
in the Off position, the Peak Amper-
age control will be a slave to the re-
mote amperage control, which is a
slave to the Amperage control on
the welding power source. The
Background Amperage
does not function when Pulser
switch is in the Off position.
