LN-10
Metric/English Wire Feed Speed Display Selection
The LN-10 Control is set up for Wire Feed Speed dis-
play in Metric units (m/min.) or English units (IPM) by
setting S2 DIP Switch 1 (Labeled “M”):
S2 switch 1 OFF = IPM (as shipped)
S2 switch 1 ON = m/min
4-Step Trigger Mode Operation Selection
The LN-10 Control is set up for 4-Step Trigger mode
operation with or without weld current interlock by set-
ting S2 DIP switch 2 (Labeled “4”).
When 4-Step trigger mode is selected on the LN-10
keypad (See Keypad and Display Operation in this
section) S2 DIP switch setting determines the 4-step
trigger operation:
S2 switch 2 OFF = 4-Step with current interlock
operation: (As shipped)
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.
S2 switch 2 ON = 4-Step without current interlock
operation:
1) Closing Trigger initiates gas flow.
2) Opening Trigger initiates gas preflow timer fol-
lowed 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
The LN-10 Control is set up for Security Mode (See
“Security Mode” in this section) by setting S2 DIP
Switch 3 (Labeled “S”):
S2 switch 3 ON = Security mode ON
