CONTROLS (PROGRAMMING CENTER):
DIGITAL DISPLAY: Visual display to supply welding motion information to operator.
SHIELDING GAS PREFLOW: Programmable time to allow the flow of shielding gas prior to striking
the arc.
TRAVEL SPEED: Speed at which the unit moves during welding.
WELD LENGTH: Distance the unit travels forward while welding in Skip mode.
BACKUP DISTANCE: Distance the unit travels in reverse after completed weld length.
SHIELDING GAS POSTFLOW: Programmable time to allow the flow of shielding gas after the arc
has extinguished.
SKIP LENGTH: Distance between welds. (Must include backup distance).
INCREASE VALUE: Pressing this button increases the value shown in the digital display.
DECREASE VALUE: Pressing this button decreases the value shown in the digital display.
FUNCTION SELECT: Allows the user to cycle through the welding programming functions.
SKIP/CONTINUOUS MODE SELECT: Allows the user to select skip mode or continuous mode for
the welding operation.
SKIP WELD INDICATOR LIGHT: When illuminated the machine will weld in skip mode.
CONTINUOUS WELD INDICATOR LIGHT: When illuminated the machine will weld in continuous
mode.
Note: It is possible to change from Continuous to Skip welding “on-the-fly”. To change modes, press
the Continuous/Skip Select button. If the machine is making a continuous weld, the backup function
and postflow will occur immediately. The machine will move the programmed skip distance and
proceed to make the programmed skip welds. If the machine is making a skip weld, the machine will
continue to weld until the Continuous/Skip Select button or the Stop button is pressed.
PUDDLE DELAY:
There are two internal settings in the Control Module that do not appear in the normal setting
selection on the control panel keypad/display. These are time delays at weld start and stop, when
the wire feed is on but travel is stopped, in order to allow for puddle buildup.
To set the time delays:
1. Power off, (power switch on back of control box); hold Cycle Stop button in, and turn power
on. Release Stop button. LED No.1 and 3 should light; and the display shows the start puddle
build time.
2. Adjust delay time as required using UP and DOWN arrow buttons.
3. Briefly push Function Select (cycle settings) button. LED No. 3 and 5 should light, and display
shows the end crater fill time.
4. Adjust delay time as required.
5. Push Function Select button again, then power off.
6. Power on to operate machine as usual, now with new settings in place.
