Power REAM
™
Robotic Torch Maintenance Center
Maintain high quality and productivity in your MIG robotic welding cell with the
Power REAM from Lincoln Electric. This automatic nozzle cleaning station removes
and reduces spatter accumulation for improved performance. The Power REAM
clamps the torch nozzle firmly in place while a constant torque air-motor drives a
high-speed reamer, cutting away spatter from the nozzle, contact tip, and gas
diffuser. A vortex action anti-spatter sprayer provides a radial spray pattern to
uniformly coat the inside of the nozzle for superior protection against weld spatter
buildup.

Advantage Lincoln
• The Power REAM delivers features unmatched in current competitive
models. The design of the Power REAM offers a simple pushbutton
“No Error” programming technique, with the added advantage of
interactive process monitoring.
• The Power REAM is the only reamer to offer an automatic retry
feature. It detects when excessive spatter builds up, preventing the
reamer from fully extending into the nozzle. When this occurs, the
reamer retracts and automatically retries.
• Diamond-shaped clamp design provides a positive, self-centering
grip on all nozzle sizes.
• Input and output signals are easily configured, allowing easy
integration for all makes and models of robot systems.
• Maintenance features such as on-board diagnostic indicator lights
and error codes allow trouble-free setup, fast maintenance, and easy
replacement of standard components.
• One year warranty on parts and labor.
• Standard integrated wire clipper provides consistent wire stickout
and removes the ball end of the welding wire to provide superior arc
starting performance for .030”- 1/16” (0.8-1.6mm) solid wires.

PERFORMANCE
The Power REAM controls the entire reaming process with its internal
microcontroller. Every aspect of the reaming cycle is commanded,
monitored and checked by the controller. The feedback signal to the
robot is a true “complete” signal indicating that the entire sequence has
been executed without error.
KEY CONTROLS
1 Fail-safe reset pushbutton overrides the
microcontroller’s commands to the cylinders
and sends them back to their home position.
2 Diagnostic LEDs are visible to an operator
and provide an indication of the position of
the air cylinders. If an error occurs, corresponding flash error codes make troubleshooting much easier.
3 “No Error” programming: The setup push-
button is used to sequence the reamer solenoids for easy programming of the correct
position the very first time. Subsequent
pressing of the button will raise the reaming
head (without spinning the ream bit), then
grip and release the nozzle.
4 Easy configuration of sinking vs. sourcing
inputs and outputs. No need to open the
case to set internal dip-switches during
installation!
-Error signal feedback to the robot: If an
error occurs in the process, then the
Power REAM returns to its home
position and sends an error signal to
the robot.

QUALITY AND RELIABILITY
• Powerful constant torque drive system provides non-stall capability.
The motor travels with the reaming bit, a design feature that aids
reliability and extends motor service life, up to 2.4 million cycles.
• Reaming bits are precision manufactured from tool steel with
titanium nitride coating.
• Dry-run feature helps prevent accidental damage to the unit.
• Synchronous timing belt does not allow slippage, avoiding excessive
belt wear.
• Wire cutter jaws designed for up to 90,000 cycles.
• One-year warranty on parts and labor.
