2. Description
The cross slide design provides horizontal or vertical movement of welding equipment. Two cross slides may be installed to provide X-Y (both horizont-
al and vertical) movement of welding equipment.

! Turn off wire feeder and weld-
ing power source, and discon-
nect input power before work-
ing on unit.
! Disconnect and lockout/tagout
input power before working on
unit.
1 Two Units Mounted Together
. Weld spatter, dirt and dust can af-
fect cross slide operation. Mount
in a suitable location.
The 6-3/4 in. (171 mm) square mount-
ing hole pattern in the cross slide car-
rier permits mounting one cross slide
on top of another to provide X-Y
movement.
Install welding equipment on carrier
plate using customer supplied 3/8-16
in. cap screws.
. Mounting screws must not
interfere with carrier travel.

5. Bearing Adjustment Procedure
. Using callout items from the parts list to perform the following procedure.
The guide wheels are fastened to the wheel plate with special mounting bolts. These bolts pass through shouldered bushings that are inserted into
the guide wheel. There are two types of bushings; the fixed or concentric (callout item 12), and the adjustable or eccentric (callout item 13). The eccent-
ric bushing has hexagonal flats.
Pre-Load Guide Wheel Adjustment:
1. Check concentric guide wheel mounting bolts for tightness.
2. Loosen the eccentric guide wheel mounting bolt just enough to allow rotation of the eccentric bushing. Make the following adjustments in small
increments.
3. Rotate the eccentric bushing to a point where the guide wheels contact the track.
4. Hold the guide wheel firmly between your fingers and move the wheel plate along the track. At the same time, rotate the bushing to a point where
the guide wheel does not skid on the track. Tighten the wheel bolt snugly so that this temporary adjustment holds.
5. Repeat this procedure on the second eccentric guide wheel.
6. A proper adjustment is achieved by repeating steps 4 and 5 until a uniform resistance to motion is attained by “feel” along the entire track.
7. Fully tighten the eccentric wheel bolts to fix both adjustments.
. Both eccentric wheels need to be adjusted prior to performing this final tightening to avoid binding of the carriage.
8. Apply wicking thread locker to wheel bolt threads from top of wheel plate. Use loctite 290 or equivalent.
