3.6.2
PWF4 Wire Feeder
The PWF4 wire feeder mounts on the robot arm. This 4-roll wire feeder provides
reliable wire feeding at rates up to 750 inches per minute (IPM). An integral gas
valve provides fast gas response time. The wire feeder has an inch forward button
to help simplify set-up and reduce change-over time. Interchangeable feed rolls are
used to accommodate different types and sizes of wire. A Shock Sensor Override
switch located on the front of the feeder is used to recover from torch impact.
3.6.3
Universal Welding Interface (UWI)
The UWI provides microprocessor control to the wire feeder and MotoArc series
power source. It scales the signals from the controller to the appropriate levels
required for control of the welding components. It also provides isolation of the
power source analog signals.
NOTE:
Some power sources available with the ArcWorld II-200 system do not use the UWI. For more
information specific to your system, refer to the vendor manuals shipped with your system.
3.6.4
GMAW Torch
The ArcWorld system uses either an air-cooled or a water-cooled robotic/automatic
GMAW torch. These are heavy-duty torches designed for quick replacement while
requiring minimum robot reprogramming. The GMAW torch is installed at the end
of the robot wrist. For applications that use the water-cooled torch, the ArcWorld
system includes a suitable water circulator kit.
3.6.5
Motoman Torch Mount
A Motoman Torch Mount protects the robot, workpiece, fixture, and positioner. It
provides multi-directional impact detection, including Z-axis collisions. Torch
impact causes a system E-STOP and immediately stops all system operation.
Servo power is removed from the system and brakes are applied to the robot. All
positioner and door motion is also stopped.
