Welding Power Supply Wettings
Make sure the Weld Power Supply is in the “REMOTE CONTROL” position, if applicable, to
insure complete command of the remote voltage control and contactor circuits.
Final Control Adjustments
Consistent setting of Rotation speed allows repeatable results regardless of bore size.
Rotation Speed is dependent on Bore size and Travel Speed of the weld process. Travel speed
is the linear movement speed of the torch along the Bore surface, measured in Inches Per
Minute. (IPM)
The operator is required to make a calculation regarding his intended Travel Speed, related to
the Bore size to be welded in.
MIG Spray transfer Travel Speed target is 10 IPM to 25 IPM.
MIG short arc Travel Speed target (in the horizontal welding plane), can range from 18 to 22
IPM.
To accurately set Rotation speed, reference Figure 11 “Travel Speed Constants” Multiply the
Bore size in inches by the Seconds per Inch of Diameter.
For example, welding at 16 IPM travel speed, with a Bore size of 57 inches, take the Seconds
Per inch of diameter value, “11.7” x 57 = 666 seconds, or 11 minutes per rotation.
Adjust the Rotation speed dial to a coarse setting, then hold Rotation Jog and time the spindle
for one revolution. Make necessary changes to the Rotation speed Dial to attain the proper
parameter.
To speed up the process, the time can be measured in 1/4 of the bore, to prevent waiting for the
spindle to move for one complete revolution.
Quick Tip
Another method, slightly less accurate but faster, is to mark a 1 inch long linear section of the
Bore in an area where the torch traverses during rotation. This 1 inch space will be used as a
timing gate, or marker.
Refer to Figure 11 “Travel Speed Constants”, showing “SECONDS TO TRAVEL ONE LINEAR
INCH.
EXAMPLE: At 20 IPM travel speed, the torch takes 3 seconds to travel 1 linear inch. This is a
preferred method for quickly roughing in the rotation speed.
For more accuracy in this timing method, increase the length to 5 inches, and make the
necessary changes to the time constant.
