C.O.
The EXTENDED FUNCTION parameter CURRENT OFFSET (
C.O.C.O.
C.O.C.O.
C.O.) provides current
adjustment in either [kA] or [%] in OPERATE mode without going into PROGRAM mode.
With this parameter, an adjustment limit window is set within which the weld CURRENT can
be changed. Only weld CURRENT can be changed this way and all other SCHEDULE
parameters remain unchanged. There are two CURRENT OFFSET modes – CURRENT OFFSET
FOR SINGLE DISPLAYED SCHEDULE, and CURRENT OFFSET FOR ALL SCHEDULES.
1. CURRENT OFFSET FOR SINGLE DISPLAYED SCHEDULES
Changing the CURRENT for a schedule only affects the displayed schedule. This is
useful when a change is needed because of an individual part change.
2. CURRENT OFFSET FOR ALL SCHEDULES
Changing the CURRENT for any individual schedule, within the CURRENT OFFSET
window, will affect all schedules (00-49) programmed in the control. Offsetting of all
schedules may be useful when a machine function (i.e., a shunt) increases in resistance,
affecting all weld schedules.
CURRENT OFFSET PROGRAMMING FOR SINGLE DISPLAYED SCHEDULES
To program the CURRENT OFFSET limits for SINGLE DISPLAYED SCHEDULES:
1. Put the control in PROGRAM mode.
2. Click SELECT until the DATA display shows

5. Press ENTER.
For a SINGLE DISPLAYED SCHEDULE, the CURRENT OFFSET may be any value from 01
to 19 in units of percent [%]. This value will set maximum and minimum OFFSET limits for
programmed CURRENT. CURRENT can be changed within these limits without going into
PROGRAM mode.
CURRENT OFFSET PROGRAMMING FOR ALL SCHEDULES
To program the CURRENT OFFSET limits for ALL SCHEDULES:
1. Put the control in PROGRAM mode.
