6.4 Weld Schedule Parameter Menus
The WC 1 controller can support several different options. Depending on which options are
installed three different menus will be displayed. Each menu is specific to the available functions
and features that are installed. Placing the key-lock switch to the “RUN” position enables the edit
function. One of the following Program menus will be displayed.

DISPLAY PARAMETER DESCRIPTION RANGE UNITS
START CURRENT
AMP = Weld cycle start current level. 1 - 500 Amps
START DELAY
TIME = The time period at the Start current level. 0 – 60.00 Sec.
RAMP UP TIME
TIME = The time that will be used to ramp the welding
current from the start to the run value. 0 – 60.00 Sec.
RUN TIME CURRENT
AMP = The current level that will be used during the run
time portion of the weld cycle. 1- 500 Amps
SPOT WELD TIME
TIME = The time period at the run current. If set the weld
sequence will automatically terminate at the end
of this time. If zero the user must clear the Cycle
start signal to terminate the weld cycle. 0 – 650.00 Sec.
PERCENT TAPER
TAPER % = The percent of run current that will be reached at
the end of the taper event. 1 – 100 %
TAPER DELAY TIME
TIME = The time period to perform the current taper
event. 0 – 600.00 Sec.
RAMP DOWN TIME
TIME = The time period used to ramp the current from the
Taper % level to the end current level. 0 – 60.00 Sec.
END CURRENT
AMPS = The current level that will be used during the end
time period. 1 - 500 Amps
END DELAY TIME
TIME = The time period at the end current level. 0 – 60.00 Sec.
PULSE MODE
MODE = Enable/Disable the pulse weld mode. If enabled
the pulse mode will be active from the start of the
ramp up event to the end of the ramp down
event. 0 – 1 Yes/No
PULSE ON TIME
TIME = The time period at the run current level when the
pulse mode is active. .001-60.000 Sec.
PULSE OFF TIME
TIME = The time period at the background current level
when the pulse mode is active. 0.001-60.000 Sec.
% BACKGROUND AMP
AMP % = The percent of the peak current value that is used
for the background current level. 1-100 %
SELECT SCHEDULE
SCHED = Select the user defined weld schedule and read
the schedule from weld memory into the active
weld schedule parameters. 1 – 32
SAVE SCHEDULE
SCHED = Write the current active weld schedule to the
specified schedule number in the weld memory. 1 - 32
