Pwf Wire Feeder; Universal Welding Interface (Uwi); Gmaw Torch; Motoman Torch Mount - YASKAWA Motoman WorldLite-50 System Manual

Mobility
The steel base that supports the power source for the Arc-WorldLite 50 system is
mobile. Four casters enable the power source to be wheeled away from the welding
cell for ease of service and installation.
To remove the power source, remove the two bolts that fasten the base to the
welding cell. The cross member that stabilizes the frame must also be removed
before the power source is wheeled out.

PWF Wire Feeder

The wire feeder is located on the back of the equipment frame. 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.
3.5.3

Universal Welding Interface (UWI)

The UWI provides microprocessor control to the wire feeder and MotoArc series
power source. It scales the signals from the XRC 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 Arc-WorldLite 50 system do not use the UWI. For more
information specific to your system, refer to the vendor manuals shipped with your system.
3.5.4

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.
3.5.5

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.

Safety Features

The Arc-WorldLite 50 incorporates a host of safety equipment. When all standard
safety precautions are taken, the safety equipment helps to ensure safe operation of
the robotic cell. The ANSI/RIA R15.06 Robot Safety Standard stipulates the user
is responsible for safeguarding. Users are responsible for determining whether the
provided safeguards are adequate for plant conditions. Users must also ensure that
safeguards are maintained in working order.
