I. Application
  1. Mainly used in welding hydraulic cylinder circular seam automatically.
  2. To guarantee the welding specification is even and uniform, welding seam has good and uniform appearance. It is convenient and reliable to use and the welding quality meets to the requirement.
II. Specification of Narrow Gap Welding Machine 
  1. Workpiece is positioned by special fixture and pressed by pneumatic thimble. Rotating synchronously. Loading and unloading bracket are mounted under the workpiece.
  2. Japan Omron PLC controls the whole machine operation. Workpiece rotation speed is adjusted by inverter, stepless adjustment, to improve the reliability.
  3. Japan OTC EP-500 welding power source which has good performance of arc igniting, arc stabilizing and arc ending, to ensure that the welding seam is even and uniform.
  4. The welding mode and welding specification can be preset, saved and recalled. Via touch man-machine interface, it is convenient to modify the parameter and switch the status through the man-machine touch screen. Welding length, arc igniting &ending time, welding current, welding voltage, welding speed,  oscillating frequency, oscillating scope, oscillating time, torch lifting time, lifting distance, lifting times can be all input through the interface.
  5. Welding current and welding voltage are controlled by D/A (digital analog). They can be preset and recalled in layer. To realize multi layer continuous welding when the arc does not stop.
  6. Using Morse taper No. 5 in the backtail, double brackets.
