Benefits

  • Gain significant savings in production time and amount of rework through easy to learn and use auto-programming.
  • Compact head design is ideal for smaller diameter pipe applications with limited radial and axial clearance around the weld.
  • All functions are accessible via one easy-to-use remote controller. Adaptive auto-programming makes it easy to set up the welding parameters using automatic calculation. Controller has a graphical user interface and clear color display. You can use the remote controller to create, modify, and manage programs.
  • Welding values and electrode movements can also be fine-adjusted during welding. The system automatically offers to adapt the welding program according to changes.
  • Integrated printer for printing the welding parameters on paper

SAVE 35 % IN WELDING TIME

The mechanized transportation of a welding head in A7 TIG Orbital System 300 provides a steady and accurate welding position. This enables stable welding quality and the use of optimized welding parameters during welding. As a result a shorter arc on time per weld is needed and the welder can weld more welds in a working day. The typical saving in welding time for A7 TIG Orbital System 300 is 35 % compared to manual MMA welding.
