Placing the switch in the ON position energizes the sloper con-
trols. Placing the switch in the OFF position turns off the sloper
controls.
When the sloper switch is in the ON position the output current
control on the front panel of the welding power source is invalid.
Initial Amperage Control (4) allows the desired starting current to
be set from which upslope will begin (Adjustable for the full
range of the power supply).
Final Amperage control (5) sets the welding current at the
completion of the weld (Adjustable for the full range of machine).
Up slope control sets slope time from initial current to the weld-
ing current set from .3 to 10 seconds.
Down slope control sets the slope time from the welding current
to the final current set from .3 to 10 seconds.
