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)

	M	4	S	R	+	-
ON									S2
	1	2	3	4	5	6	7	8
S2

S2 switch 2 ON = 4-Step without current interlock operation:

	M	4	S	R	+	-
ON	1	2	3	4	5	6	7	8	S2
S2

1) Closing Trigger initiates gas flow.

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)

	M	4	S	R	+	-
ON	1	2	3	4	5	6	7	8	S2

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.

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

	M	4	S	R	+	-
ON	1	2	3	4	5	6	7	8	S2
S2

S2 switch 3 OFF = Security mode OFF (as shipped)
