2DIP Switch S4 (Not For Customer Use)
DIP switch S1 allows the user to make a num- ber of choices affecting unit operation.
wSelecting Weld Amperage Or Wire Feed Speed Display (S1-1)
If the front panel DIP is set in the display amps position, the lower display (see Section
wSelecting Wire Feed Speed Value (S1-2)
The unit displays wire speed in units of inches per minute (IPM) if the English/Metric wire feed display DIP is in the English position. The unit displays wire speed in meters per minute (MPM) if the DIP is in the metric position.
wAdjusting Range Limits (S1-3 & 4)
The lock feature provides a means of regulat-
ing unit settings, but still allows some level of adjustment through the Adjust control. When a lock position is used, the lock applies to all programs. Two DIP switches are dedicated to locking unit settings. Four possible combina- tions of the two DIP switches provide the fol- lowing settings: Locks Off, Locks On ± 5%, Locks On ± 10%, and finally Locks On ± 20%.
If the wire speed is at 300 IPM when the lock DIP is activated, and the lock range is set at
±10%, the operator would have an adjustment range from 270 to 330 IPM.
.To changing Lock %, proceed as follows: Turn power Off
Place DIP switches
Turn power On and Off
Place switches 3&4 in desired new settings
Turn power On and Off.
Trigger Hold and Dual Schedule function nor- mally when locks are enabled.
wSetting Display Hold Feature (S1-5)
If the display hold DIP is in the “Hold On” posi- tion, the unit will hold the last weld information for 5 seconds following weld termination. If any front panel push button is pressed, or if the Adjust control is activated, the display hold feature is terminated.
wSetting Current Detect Override (S1-6)
Current detect override is used to disable run- in when a welding power source is used that doesn’t provide current feedback through the
wDefining Motor Speed (S1-7 & 8)
Switches 7 and 8 allow the user to define whether the motor in use is normal speed
