Rotary Welding Equipment

The BANCROFT WELDA-ROUND family of automated welders are versatile and durable production tools designed to weld a broad range of parts.  They are designed to economically satisfy your production needs without the added costs of highly engineered systems. These rotary welders are also commonly referred to as: fitting welders, circle welders, header welders or port welders.

300 WELDA-ROUND ROTARY TORCH WELDING SYSTEM

Repetitive accuracy, ease of use, and cost efficiency are just a few advantages built into the MODEL 300.  The 360-degree torch rotation plus an adjustable overlap is designed to produce fast, repeatable, flat circular or contoured welds.
This economical Bancroft Ring Welder is an affordable alternative to other customized welding machines. Our circle welder machines are heavy duty pieces of equipment that can handle the toughest jobs and are equipt with the latest in automated welding technology and digital controls.

600 WELDA-ROUND CIRCLE WELDER

BANCROFT’s dual arc technique provides unbeatable advantages for users who require speed and quality above all else. With the MODEL 600 Fitting welder, arc time is reduced by half due to the rotating torches, each traveling 180 degrees plus an adjustable overlap. Part distortion is greatly reduced or eliminated by starting the welds 180 degrees apart. Setup and tooling are simplified by rotating the torches rather than the workpiece.

  • DC rotation drive.
  • Floor mounted operator console.
  • Fabricated tooling arm.
  • 750 lb head clamping force.
  • Adjustable 8-inch vertical stroke.
  • 50-550 or 100-1100 IPM BANCROFT wire drive.
  • Two standard air cooled torches.
  • Two independent rack and pinion torch adjusters.
  • .4 to 4.8 RM rotation speed.
  • 110VAC power & shop air on all machines.
  • Four torch configurations.
  • Water cooled torches.
  • Skip or partial weld.
  • Auto head raise and lower.
  • Arc screen.
  • Rotation speed range options.
  • Safety light curtains.
  • Servo motors.
  • Special frame configurations.
