Pipe welding

Making life easier for job-site welders Lincoln Electric has launched new CrossLinc™ Technology-enabled welding equipment, providing

advantages for the construction, shipbuilding, barge, heavy fabrication and other markets. The Flextec ® 350X welder and LN-25X wire feeder use a proprietary communications protocol to transfer operator voltage adjustments at the feeder to the power source hundreds of feet away using a common, copper weld cable. No additional control cable is required. The result is greater safety, quality and productivity for job-site and fab-shop environments. The new Flextec 350X multi-process welding power source delivers premium arc performance for all DC wire, stick and TIG processes and gouging up to 4.8mm ( 3 / 16 "). Engineered for outdoor use and harsh environments, the IP23- rated welder features fully protected components.

and protected electronics, and a tough, flame-resistant case.

With an output range of 5 to 425 amps, the Flextec 350X is rated at 300 amps, 32 volts at 100 per cent duty cycle, or 350 amps, 34 volts at 60 per cent duty cycle. The compact new model weighs only 34.9kg (77lb).

The feeder is rated 450 amps at 60 per cent duty cycle, with a wire feed speed range of 50-700" per minute. Wire diameters range from 0.6 to 1.6mm (0.023 to 1 / 16 ") for GMAW wires, and 0.8 to 2mm (0.03 to 5 / 64 ") for cored wires. The LN-25X can handle 203 or 305mm (8" or 12") spools, and weighs less than 16kg (37lb). The ‘X’ in the LN-25X name indicates that the feeder is designed for Lincoln Electric’s CrossLinc Technology- enabled operation, as well as across- the-arc operation. Lincoln Electric designs, develops and manufactures arc welding products, robotic arc welding systems, plasma and oxy-fuel cutting equipment. Headquartered in Cleveland, Ohio, USA, the company has 47 manufacturing locations, including operations and joint ventures in 19 countries, and a worldwide network of distributors and sales offices covering more than 160 countries.

The Flextec 350X is offered as a Construction model for connection with across-the-arc or CrossLinc-enabled feeders, or a Standard model compatible with a greater selection of feeders, including across- the-arc, analogue, digital or CrossLinc Technology- enabled wire feeders. Multi-operator four- pack and six-pack rack systems are available for each model. Built using the same design qualities of the LN-Pro product line, the LN-25X feeder is designed to be simple, reliable and easy to service when necessary. LN-25 Pro feeders feature a rugged Maxtrac drive system, dual range wire feed speed, encapsulated

CrossLinc Technology provides more welding control with fewer cables
