The UWC™ Universal Weld Control can bringtotal weld process control to your system. Based on an embedded micro controller, this unit provides two 0-10 VDC programmable outputs to control the welding power source. Provides interface to our DMC II™ DC MotorControl, MSC II™ Micro Step Control and Remote I/O Control.


The microprocessor based Modular Weld Controller is the main control module and provides all control and communication functions and can program external motion control axis via the Local Area Network (LAN) port. The controller can support up to four stepper motor controlled axis, using the MSC-1000™ Micro-step Controller, and four DC servo controls, using the DMC-1000™ DC Servo Controller. The MWC-1000™ provides all external Input / Output control interface and electrical connections to user supplied components.

  MSC II™  

The MSC II™ is a microprocessor based stepper motor controller which provides a 1/10 micro stepping output to operate most stepper drive motors requiring 1.0 – 6.5 amps/phase current.  The controller is designed to be used with the CWT torch positioning slides and the CWT weld sequence controller.  It can also be used as a stand-alone positioning controller.  The MSC II has an isolated RS-485 port, which can be configured to allow off-line programming and control of the stepper motor.  The MSC II can be configured to use the Local Area Network (LAN) port which allows the CWT weld sequence control to program and control the CWT torch positioning slide assemblies.

  DMC II™  

The DMC II Motor Controller is a PWM motor speed controller using an embedded micro controller to provide motor speed regulation and torque compensation. There are two version of the DMC II controller. The DMC II-LV has a 24 VDC @ 6.5amps output and the DMC II-HV has a 100 VDC @ 2.8 amps output. The DMC II-LV controller can be used to control 24 volt permanent magnet (PM) motors up to 150 watts. The DMC II-HV can be used to control 90 Volt permanent magnet motors up to 250 watts. The DMC II is designed to be used with the CWT Weld Sequence Controllers or a user supplied controller. The DMC II also provides a RS-485 serial port configured to support Modbus RTU protocol.  This port can be used to Operate and configure various features of the DMC II.

  HSA-2000™ and VSA-2000™  

Our Horizontal Slide Assembly is a precision linear motor control device that provides exacting horizontal movement for cross-seam positioning and/or torch oscillation. The slide assembly is intended to be used with our MSC-1000 Micro-step Controller which provides the necessary control functions and drive power to the stepper motor drive.

Our Vertical Slide Assembly is a precision, linear motion control device that provides exacting vertical movement for torch-to-work positioning. The ball screw drive design with linear ball rail system provides high load carrying capability, smooth operation, superior response and excellent repeatability.


Computer Weld Technology's Automatic Torch Control (ATC II™) is a compact, lightweight, weld torch manipulation control system comprised of the microcontroller based Automatic Torch Control and a stepper motor driven Linear Slide Assembly (LSA). This system is capable of providing independent control of all torch movements in the vertical plane. Employing patented "Thru-Arc™" tracking technology, the system provides automatic torch height control for both GTAW, PAW and GMAW applications.


Weld Oscillator Control Systems are a compact, lightweight, weld torch manipulation control system comprised of the micro-controller based Weld Oscillator Control and a stepper motor driven Pendulum Oscillator Assembly or Linear Slide Assembly. Both systems provide a user definable 50 sequence Programmable Logic Controller (PLC) with four 24 vdc inputs and two N.O. relay contacts. The RS-232 serial port is provided for off-line programming and system configuration and can also be used to remotely control both the WOC-500 and WOC-1OOO. The second component is the pendulum type oscillator or linear slide that are driven by a stepper motors which provides high reliability and low maintenance costs. The oscillator can be installed in-line or at 90 degrees and because of the compact configuration, is usable in confined spaces.
