SETUP AND OPERATION, CONT'D.
ADDITIONAL CABLES
The circle welders are supplied with the following cables:
1. CWO-3139 50' (15 m) power cable that connects the power source to the cable connector on the top gear
of the machine.
2. CWO-3040 50' (15 m) weld cable that connects the lead coming out of the top of the machine using the
quick connect connector to your power supply.
3. CWO-9406 50' (15 m) gas shielding hose that connects the gas fitting on the top of the shaft to your
shielding gas supply.
WIRE SPEED AND VOLTAGE ADJUSTMENT
The wire speed control on the front of the CWO-3332 Wire Feed Control
box has a dial that is calibrated directly in inches per minute. Set the
voltage using the control on the power source.
RISE AND FALL OF THE CAM
All circle welders are equipped with a rise and fall cam assembly. The
cam assembly must be aligned before any other settings can be made.
To align the cam rotate the machine so the horizontal rack is parallel to
the pipe, then adjust the gun holder so it is perpendicular to the horizontal
rack. Position torch tip to top dead center of joint. Loosen the set screws
in the brass block on the cam, and rotate the cam to the vertical position
as shown. Refasten set screws.
WHEEL ADJUSTMENT
The CW-5AX Racking System CWO-1660 and the Small Vertical Racker CWO-1685
are equipped with adjustable wheels. Always check these components for proper
wheel adjustment before using the machine. The wheels need adjustment if you
can cock or wiggle the components out of alignment. The wheels should be snug
but not prohibit movement along the path of travel. The wheels with the hex stand
offs are adjustable. To adjust the wheels, loosen the hex bolt (A) until the adjustable
bushing (B) can be rotated. Correct the wheel alignment by rotating the adjustable
bushing (B). Once adjusted, hold the adjustable bushing (B) while tightening the hex
bolt (A). Recheck alignment.
MACHINE CONTROLS
Operational parameters can be set using the two control boxes. Please refer to the
sections in this manual entitled CWO-3332 Wire Feeder Control for descriptions of
the various welding parameters that are available, as well as CWO-6210 Rotation
Control for descriptions of the various speed and directional capabilities.
CAM SETTING
The cam setting is equal to distance “B” subtracted from distance “A”.
Example:
Let A=3 and B=2
3-2=1
The cam setting is 1.
MAKING A WELD
1. Position the gun to start position using the CWO-1660 Racking System.
2. Connect the ground cable to the workpiece. The ground cable must make good electrical contact with the work.
3. Position the electrode in the joint. The end of the electrode may be lightly touching the work.
4. With manual/auto switch in the “OFF” position, set rotation direction and speed.
5. Weld process and rotation are both started by throwing the manual/auto switch to auto.
6. Weld process and rotation are stopped by throwing the manual/auto switch to “OFF”.
