2. Secure Carriage on Rail
A. Select the correct pair of holes on each side of the carriage for the rail diameter being used (see chart,
below). If the wheels are not attached to the correct set of holes, remove the wheel brackets and bolt
them in selected holes. Tighten the bolts until the brackets are snug but still free to rotate.
B. Loosen the adjustment knob to separate the two halves of the split carriage. Loosen and turn the clutch
knob counterclockwise to put the drive in the declutched position.
C. Place the carriage on the ring rail with the wheels in the rail grooves. Close the cam handle and move
the carriage back and forth a few inches. The wheels on their mounting brackets will align themselves
correctly with the rail grooves.
D. Verify that wheels are properly aligned, then tighten the wheel mounting bolts to lock them in position.
Rotate the clutch knob clockwise to engage the drive pinion with the rack.
E. Verify that pinion is properly engaged in rack. The correct wheel position will provide a minimum of 1/8"
(3.175 mm) engagement between the drive pinion and the gear rack.
3. Position and Clamp Welding Gun
Secure welding gun in the all-position clamp located on the end of the height control mechanism. Arrange
cables so that they do not interfere with the movement of the machine and secure in the cable anchor at
the back of the machine.
DETAILED SETUP
1. Install Rail
The Tube Carriage is designed for use with Bent Rigid Rail (BRR) or Ring Rail. The exact outside diam-
eter (OD) of the work piece, including coating, must be known when ordering rail. Minimum pipe OD is
9 inches (229 mm). Rail is custom bent for each OD and features adjustable feet to accommodate pipe
ovality and deviations in coating thickness.
