1.0 GENERAL DESCRIPTION
1.0 FUNCTIONAL DESCRIPTION
The Lincoln Electric Company Weld Oscillator Control (WOC-2) is a compact, lightweight, weld
torch manipulation control system comprised of the micro-controller based Weld Oscillator
Control (WOC-2) and a stepper motor driven Pendulum Oscillator Assembly (POA) or the Linear
Slide Assembly (LSA) and a remote operator pendant. This system is capable of providing
independent control of all torch movements in the horizontal plan.
The Weld Oscillator Control (WOC 2) provides the necessary command signals to the stepper motor
powered drive to permit the selection of the following functions from the remote operator pendant.
CONTROL FUNCTION
RUN Enables oscillation.
JOG Jog the center position in a CW or CCW direction.
SPEED Control the speed of the oscillation.
LEFT DWELL Control the dwell time on the left side of the oscillation pattern.
RIGHT DWELL Control the dwell time on the right side of the oscillation pattern.
WIDTH Control the width or amplitude of the weave pattern.
The Pendulum Oscillator Assembly (POA) is a stepper motor driven mechanical assembly that
provides the oscillation motion for weld torch manipulation. The oscillator has a single 5/8-inch
diameter output shaft for attachment of the user supplied welding torch. The oscillator module can be
installed in any position and with a maximum rotational displacement of ±15°.
The Horizontal Slide Assembly (HSA) is a stepper motor driven mechanical assembly that provides the
motion for weld torch manipulation. The HSA provides 7” of horizontal motion and has a weight
capacity of 45 lbs @ 6” from the face of the carriage. The Heavy Duty VSA provides 7” of horizontal
motion and has a weight capacity of 200 lbs @ 3” from the face of the carriage.
