w Setting Current Detect

Override (S1-1)

Current detect override is used to disable run-in when a welding pow- er source is used that doesn’t pro- vide current feedback through the 14-pin receptacle.

. Pins F & H are not present in 14 pin receptacle on machines that don’t provide current feed- back.

Install wrapper when finished.

. In the DIP switch S1 illustrations, the elevated slider on each switch is shown in white. For example, the switches above are all in the Off position.

.When DIP switch positions are changed, the unit must be

turned Off and then On again in order for the new settings to be active. DIP switches are only read on power up.

Position Settings And Results For DIP Switch S1 On PC1 And PC101

Automatic Run-In (ON)

(Factory Default)

S1-1 And S1-2

On = Run-In speed is approximately 1/2 weld wire feed speed.

Automatic Run-In (OFF)

S1-1 And S1-2

Off = Run-In speed is set using potentiometer P1 located on Motor Board PC1.

Current Detect Override (ON)

S1-1 And S1-2

On = Current detect over- ride. For welding power sources that don’t provide current feedback through the 14-pin receptacle. Run- in is inactive.

Current Detect Override (OFF)

(Factory Default)

S1-1 And S1-2

Off = Current must be detected from power sources that provide current feedback through the

14-pin receptacle to go from run-in to welding condition. Run-in wire speed is active.
