4-Step Trigger Mode Operation Selection
The STT-10 Control is set up for 4-Step Trigger mode
operation with or without weld current interlock by set-
ting S1 DIP switch 5 (Labeled "4").
When 4-Step trigger mode is selected on the STT-10
keypad (See Keypad and Display Operation in this
section) S1 DIP switch setting determines the 4-step
trigger operation:
S1 switch 5 OFF = 4-Step with current interlock

1) Closing Trigger initiates gas preflow time followed
by Run-in speed and strike voltage until arc strike
initiates welding.
2) Opening Trigger after welding arc is established
continues welding with weld current interlock.
(Breaking arc stops the feeder operation).
3) Reclosing Trigger continues welding but shuts off
current interlock function.
4) Reopening Trigger stops wire feed and initiates
burnback time, then gas postflow time.

1) Closing Trigger initiates gas flow.
2) Opening Trigger initiates gas preflow timer followed
by Run-in speed and strike voltage until arc strike
initiates welding. (Trigger is released before arc is
struck, but once established breaking arc stops the
feeder operation).
3) Reclosing Trigger stops wire feed and initiates
burnback time, then gas postflow time.
4) Reopening Trigger stops gas flow if, or when, post-
flow time is over.
Security Mode Selection
