Lincoln Electric IM10023 manual END Options Operation, Downslope Time

B-8 OPERATION B-8

END OPTIONS

The downslope, crater, and burnback parameters are used to define the end of the weld sequence. The are defined in the following:

•DOWNSLOPE determines the amount of time it takes to ramp from the weld parameters to the crater parameters. The transition is linear and may be up or down depending on the relationship between the weld and crater settings.

•CRATER parameters are typically used to fill the crater at the end of the weld and include both time and output settings.

•BURNBACK defines the amount of time the output remains on after the wire has stopped. This feature is used to prevent the wire from sticking in the weld puddle and to condition the end of the wire for the next weld. A burnback time of 0.4 second is suffi- cient in most applications.

•RESTRIKE TIME determines how long the system will try to re-establish the arc in the event of a poor start or if the arc goes out for any reason (short cir- cuit or open circuit). During restrike, the WFS and outputs are driven in an attempt to re-establish the arc.

•A restrike time of 1 to 2 seconds is sufficient in most applications.

•A restrike time of 0 seconds allows the restrike function to continue indefinitely.

END OPTIONS OPERATION

Pressing the Arc Start/End Options pushbutton after scrolling through the Start Options will illuminate the END OPTIONS LED and the Downslope Time parame- ter will show on the MSP Display.

OFF

Downslope Time

Repeated pressing of the Arc Start/End Options pushbutton will toggle through the parameters. Turning the Mode Select Panel Control while on a parameter will change its value. When the Crater Time is set to a value other than OFF, the END OPTIONS LED will blink synchronous with the WFS or Amps LED (depending on CC or CV Weld Modes) and with the Volts LED located on the Dual Display Panel prompting the user to enter these parameters. The parameters that can be set by the user in the END OPTIONS will be as follows:

DOWNSLOPE TIME

CRATER WFS/AMPS

CRATER VOLTS

CRATER TIME

BURNBACK TIME

RESTRIKE TIME

Use the Mode Select Panel Control to select the desired delay time. Press the Weld Mode Selector to exit the End parameters.
