Warning:
To prevent personal injury or damage to the equipment
or workpiece being welded, always hold the welder in
place before releasing the column damps. This
procedure may require two people.
If the converter and booster are not assembled:
1. Raise the welding head by loosening the upper and lower column
clamps and turning the elevation knob clockwise. After raising the
head, re-tighten the column clamps.
2. Open the carriage door by loosening the captive screws.
3. Clean the mating surfaces of the converter and booster, as well as the
converter's threaded hole and the booster's threaded stud. Remove any
foreign matter. Make sure the stud is tight in the booster.
