Operation with asettingof less than 30 per

an acceptable wire feed speed adjustment. Selecting

Changing Speed Change Gears
Change the Speed Change Gears as follows:
1. If speed change gear changing is necessary, re
move the speed reduction gear cover by removing
the two 1/4 inch screws.
2. Loosen the two bolts fastening the Drive Roll
Assembly to the base of the control/feeder.
3. Slide the drive roll assembly forward.
4. Remove the speed change gear from the Drive
Roll Assembly.
5. Remove the speed change gear from the drive
