5Time LED

The LEDs below the display illuminate to in- dicate which value is being shown.

At any time while welding, the unit permits the adjustment of the weld sequence voltage and overrides the display of actual arc volt- age.

•If the unit is displaying a welding sequence that can be timed, the welding time display mode is entered by pressing the upper dis-

play push button repeatedly until welding time is the active parameter in the upper display. At idle, the upper display toggles between showing weld voltage or weld time, with subsequent presses of the up- per display push button.

•The unit defaults to displaying welding voltage when a welding sequence display mode is first entered.

•If the weld sequence has a time set (as in spot time), after the weld program is com- pleted, ERR TRG 1 will be displayed to in- dicate the weld program is complete. Re- lease trigger to clear error.
