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)
2. Hold Cycle Stop button in, and turn power on.
3. Release Stop button. (LED No.1 and 3 should light; and the display shows the start puddle
build time.)
4. Adjust delay time as required using UP and DOWN arrow buttons.
5. Briefly push Function Select (cycle settings) button. LED No. 3 and 5 should light, and display
shows the end crater fill time.
6. Adjust delay time as required.
7. Push Function Select button again, then power off.
8. Power on to operate machine as usual, now with new settings in place.
