8.Define the wire feed start delay as desired.

Wire feed start delay is the amount of time between the end of initial current and when the wire feed user relay (see Section 2-3) changes states. A delay time of 0 means the wire feed relay changes state immediately at the end of initial current. A delay time of 3.5 means the relay changes state 3.5 seconds after the end of ini- tial current.

The wire feed relay change cannot be delayed beyond the end of weld current. When weld current ends, the wire feed relay changes states whether or not the de- fined start delay time has elapsed.

The range for start delay time is 0.0 to 25.0 seconds, in increments of 0.1 seconds.

10.Define the wire feed stop delay as desired.

Wire feed stop delay is the amount of time between the end of weld current and when the wire feed user relay (see Section 2-3) changes states. A delay time of 0 means the wire feed relay changes state immediately at the end of weld current. A delay time of 7.0 means the relay changes state 7.0 seconds after the end of weld current.

The wire feed relay change cannot be delayed beyond the end of postflow. When postflow ends, the wire feed relay changes states whether or not the defined stop delay time has elapsed.

The range for stop delay time is 0.0 to 25.0 seconds, in increments of 0.1 seconds.
