Automated GTA/Plasma Welding Systems

PWT offers new and used automated welding machines, from a 4-axis bench-top welding system to more complex systems such as the Sciaky CNC Fusion Systems (5-7 axes). We also provide powerful retrofits to extend the usefulness and life of selected automated welding equipment.


 Sciaky AcuWeld 500, 1000, & M5 Systems (refurbished, like new)

  • Computer control
     
  • Five or six axis closed loop control of the servo axes
     
  • All welding parameters controlled within +/- 1% of the programmed values
     
  • Low heat input welding due to synchronized pulsation of the weld current & filler wire feed
     
  • PWT's precise wirefeeder and specialized gas shields come installed on machine
     
  • PWT can retrofit any of these machine's existing control with its new Advanced U-Weld control
     
  • "PWT can retrofit any of these machines with a Stenning Custom Model MV-103XL Weld Monitoring Camera System

Three control options are available:
  1. Basic Control consisting of:
    • Small Size PLC
    • Programming of welding parameters is accomplished via potentiometers located on a small pendant.
    • Weld duration time is based on a timer and is programmable.
    • Welding can be accomplished utilizing the X-axis or rotary axis.

  2. Advanced Control consisting of:
    • Medium Size PLC
    • Programming of welding parameters is accomplished via a touch screen located on the operator's pendant.
    • Weld current, travel speed, and arc voltage have override adjustment.

  3. NC Control consisting of:
    • NC Controller utilizes a DSP processor with the control card located in the PC chassis.
    • Programming of welding parameters is accomplished via an operator console with a CRT keyboard.
    • Programming is NC language.
    • Operator pendant is used to start and stop the weld program.
    • Weld current, travel speed, and arc voltage have override adjustment.
    • Motorized axes jogs are provided in low speed, medium speed, high speed, and in increments of 0.01" and 0.1"

Optional features include:
  • Weld Gap Measurement
  • Camera System
  • NDT
  • Networking
