New Solid-State Welding

Control From Duraline —Literature Available

Duraline, Central Islip, N.Y., manufacturer and supplier of multiple-operator welding equip- ment to the shipbuilding and ship repair industry, will intro- duce its latest state-of-the-art, solid-state welding control at this year's AWS Welding show, to be held in Kansas City, April 27-29.

The new solid-state welding control is designed to operate off standard 80VDC rectifier power supplies, and expands the capa- bilities of the conventional M-0 system, currently limited to man- ual arc welding with straight or reverse polarity, to include arc driven, semiautomatic hard and fluxcore wire welding processes.

With the all-new design, weld- ing power is controlled and sup- plied to welder by means of a high frequency switching system which pulses the 80VDC rectifier power output at the point of welding. Power is supplied to cre- ate the weld puddle with little or no loss. The result is a reduction in the number of rectifiers re- quired to supply power to a given number of welders that can be serviced from a given DC recti- fier.

Overall system efficiencies of 85 percent are reported and bet- ter than 60 percent savings in energy costs.

Free literature is now avail- able completely describing this revolutionary new system.
