USING CURRENT OFFSET
This feature is very useful when a PROGRAM LOCKOUT key switch is used. An operator
may change the CURRENT without changing any other welding parameters and without going
into PROGRAM mode. The operator may increase the operating PERCENT CURRENT only
up to BASE CURRENT plus CURRENT OFFSET, or decrease the operating PERCENT
CURRENT down to BASE CURRENT minus CURRENT OFFSET.
To change programmed CURRENT, within the OFFSET limits in [%] or [kA], in OPERATE
mode:
1. Click SELECT until FUNCTION indicator LED stops at PERCENT CURRENT.
2. Use the DATA push buttons to increase or decrease the PERCENT CURRENT by
pressing or holding either DATA push button.
3. Press ENTER only for CONSTANT CURRENT mode in [kA]. For CONSTANT
CURRENT mode in [%] or for NON-CONSTANT CURRENT mode, data will be stored
immediately after pressing either DATA push button.
If a value greater than allowed by maximum OFFSET is programmed, the control will store
and display maximum PERCENT allowed. Similarly, if a value lower than allowed by minimum
OFFSET is programmed, the control will store and display minimum PERCENT allowed.

39: PERCENT CURRENT will
be increased or decreased with the same OFFSET in percent in all schedules.
CHANGING BASE CURRENT
To change BASE PERCENT CURRENT, simply program the schedule as done normally by
switching to the PROGRAM mode and following normal programming procedures. In
PROGRAM mode, the display will flash between BASE CURRENT and OFFSET CURRENT
value. PERCENT CURRENT is the only weld schedule parameter that is changed whenever a
CURRENT OFFSET value is used.
