Additional Features

With the optional oscillator, plates from 1-1/4" to 2" can be joined together using the Ransome VUP. The power supply consists of a skid-mounted Lincoln DC-1000 with NA3 control and water flow panel. The standard Lincoln NR-431/NR-432 Innershield processes offer significant savings, providing deposition rates of 48 lbs/hr. The VUP is also ideal for other applications, including shipbuilding and manipulator-mounted butt-welding of 6 ft to 50 ft vertical plates. The VUP sturdy mainframe features a vertical column mounted on a carriage and roller assembly that rides on the top of tank plates. Its self-locking gear reducer with variable speed drive is electronically integrated with the welding control, which automatically adjusts speed to maintain the optimum copper-shoe-to-weld puddle relationship. The lift controls include an up/down switch, low/high speed potentiometers and rapid speed selector. Requiring just one operator, the VUP can complete 10 to 12 vertical seams per work shift.

Portable Track-Guided VUP Welding System
The Track-Guided VUP is a versatile, easy-to-use, easy-to-set-up system for in-plant vertical-up applications. It is ideal for accurate seam welding of gaped square butt and single vee-welds on plates from 3/8" to 4" and up to six feet in height. Additional track is available in six-foot heights. The VUP consists of a vertical track, a powered carriage with special Lincoln nozzle, oscillator for plates up to 4" thick, water-cooled copper dam, nozzle and seam cross, and in-out adjustment. It features the Lincoln LN9V or NA5 solid-state control and wire feeder with 50 lb. reel. This model is wheel-mounted for in-plant mobility. All parameters can be preset to monitor current, voltage and wire speed. A copper dam is automatically maintained in a fixed relation to the weld puddle. A flow regulator along with a switch in the water cooling circuit protect against no- or low-flow. The Lincoln DC1000 power supply features multi-conductor cables to supply control functions and 25 ft of double 4/0 ground cable standard. Assembly includes water hoses, wire feeder pressure rolls and inlet/outlet guides for either 3/32" or .120" diameter wire fed through 15 ft conduit.
