The Koike Aronson / Ransome Automatic Girth Welder (AGW) A.K.A. (3:00, 3 O'clock Welder, ) performs x-ray quality horizontal welds up to 20 times faster than standard manual techniques, cutting in-field welding time for storage tanks by up to 40%.

Operating at speeds from four to 105 inches per minute, the AGW can handle plates as thick as 1 ¾" and tank diameters from the largest to as small as 15'. The adjustable A-frame telescopes manually to handle six- to 10-feet high steel plates.

Ergonomically designed for efficiency, convenience, and accessibility, the AGW includes the Lincoln NA-3 solid state control and welding head fitted with nozzles, wire feed rolls, strengtheners and 50 lb. wire reels for either single or twin-arc wire.

Lincoln NA-5 controls as well as a DC-1000 power source is also available. The submerged arc flux belt mechanism ensures retention of the flux at the joint for efficient recycling.

It is available as a single sided or dual sided mobile welding station completely equipped with welding heads, all controls, flux support belts and flux recovery units.

The AGW straddles the tank shell plates, riding on serrated steel drive wheels that can be adjusted for tank diameter.

The AGW's operator platform is a sturdy and solid workstation with guardrails and all-weather curtains for operator safety and comfort. The double platform is fully equipped with its own direction and speed controls. An access ladder allows movement to the primary flux separator tank and to the side of the dual unit.
