Nachi is an industry leader in spot welding robot technology.

Nachi’s latest spot welding technology is integrated to the industries fastest industrial robots, the Nachi SRA Series, which provide the industry’s most advanced spot welding controls and software functionality. Utilizing fully integrated weld controls, all spot welding data can be directly inputted and monitored through the robot’s teach pendant. A customer is able to create detailed weld schedules unique to your application and material types with ease using the full color touch screen graphical spot welding user interface. Nachi Robotics’ SRA series reduces spot welding times by 30 percent over previous models through improved motion control, improved arm rigidity, vibration suppression and acceleration performance.

Nachi Robotics SRA robots also offer A-Trac cable management systems to simplify:

  • Routing of power cables
  • Pneumatic lines
  • Water hoses
  • Signal cables to spot welding guns
Features & Benefits

Improved Productivity

  • Servo motor driven gun allows programming to any gun tip position within gun limits.
  • Gun motion is synchronized with the robot to reduce cycle time. Programmed tip force is achieved in one-third the time of a conventional air gun.
Improved Productivity

Improved Weld Quality

  • Precise pressure control reduces welding expulsion and tip wear.
  • Impact is 3x less than an air gun eliminating workpiece deformation and reducing tip wear.
Improved Weld Quality

Enhanced Flexibility

  • One gun is now flexible enough to weld throughout a wide pressure range for variable metal thicknesses.
Enhanced Flexibility

In Process Quality Control

  • Measures thickness of parts at each weld at any pressure.
  • Automatically detect missing or misplaced parts.
In Process Quality Control

Equipment Cost Reduction

  • Simplified features and the elimination of pneumatic systems reduces initial cost.
  • Never worry about air leaks with electric servomotor driven spot welding guns.
  • Improvement of operability, longer tip life (more than 30%), and improved energy efficiency reduces operating costs.
Equipment Cost Reduction

Environmental Improvement

  • Elimination of air exhaust noise typical of pneumatic spot welding guns
  • Reduced welding expulsion
