3.1 Robot and Controller

This chapter contains brief descriptions of The Miller
Digital welding system components.
Robot and Controller
The robot controller coordinates the operation of the various welding
system components. The controller executes instruction sequences
provided in a robot job file. As the controller steps through the series of
instructions, it directs the movement of the torch, and operates the
welding power supply. The robot moves the welding torch and supply lines
through a series of programmed steps. The controller sets the speed,
direction, and position of the robot as it moves from point to point. It
communicates weld signals through a digital interface board mounted in
the controller cabinet. The controller sends command values for wire feed
speed, voltage/arc length, arcon and arcoff. The robot also selects one of
eight weld programs by setting three outputs. The Auto-Axcess DI/E
Digital power source communicates to the controller when the arc is
established, when there is a fault condition, or when the wire is stuck to
the puddle. The power source also communicates the fault type back to
the DX100.
This enhanced interface also features a pendant application which allows
weld data to be assigned to the eight weld programs. It also provides
functionality similar to Millers' File Manager Software.

Auto-Axcess DI/E Digital Power Supply

The Auto-Axcess DI/E Digital power source is a three-phase, high-
frequency, multi-process inverter welder. The welder operates at either 50
or 60 Hz frequency and 190 to 630 volts AC or DC.
™
Auto-Line automatically adjusts to line voltage, so no external
adjustments are necessary. The power source has multi-process MIG
capability consisting of standard MIG (GMAW), standard pulse MIG
(GMAW-P), Accu-Pulse (GMAW-P), Accu-Speed (GMAW-P),
Accu-Curve (GMAW-P), as well as a RMD (GMAW-SC) mode. (RMD is a
paid option on the DI welders and is standard on the Axcess E Digital
welders)
Accu-Pulse reduces burn through problems, increases welding travel
speeds, and is superior to pulse mode when welding with short arc
lengths. For even shorter arc lengths on steel Accu-Speed is available.
Accur-Curve has a softer pulse that can be used on aluminum. The
optional RMD (Regulated Metal Deposition) process is a short circuit
transfer process in which the power source alters the welding current to
improve the droplet transfer while minimizing spatter levels. It is limited to
use at wire speeds below 250 ipm (depending on electrode diameter) on
thin gauge steel applications.
The Auto-Axcess DI uses a DeviceNet interface and is compatible with the
DX100 controller.
The Auto-Axcess E Digital has the ability to use either a DeviceNet or
EtherNetIP interface. The DeviceNet interface (on the E Digital machine)
provides the same interface functionality and control as the Auto-Axcess
DI/E Digital. The EtherNetIP implementation of the Axcess E Digital
provides additional robot control for process monitoring control.
