For short-cycle applications, servo-electric welding system comprises gun, power supply, and feeder. Servo-operated Model KSE 100 gun (pictured) has intelligent referencing mechanism for exact physical positioning. Feedback system and linear motor drive control arc length and lift and plunge velocity. Model N3 power supply monitors all parameters of weld cycle, including consistent current, lift/plunge compensation, and diagnostics. Model FSE 100 feeder compensates for changes in air pressure, damaged feed hoses, and sticky loading pins. Hopper has capacity of over 10,000 studs.
