K4278-2 / FLEXTEC® 350X CONSTRUCTION/LN-25X ONE PAK®

A RUGGED MULTI-PROCESS POWER SOURCE FOR MAXIMUM FLEXIBILITY

Out on the construction jobsite or in most fabrication shops, it pays to keep it simple. The Flextec^® 350X multi-process welder is designed for that kind of environment. These multi-process welders are easy to setup and easy to operate, yet rugged and flexible enough to be used in construction, fabrication, shipbuilding and other heavy-duty applications.

CrossLinc™ Technology

• Full functionality without control cables
• Enables remote procedure setting at the feeder to improve weld quality
• Increase arc time with fewer trips to the power source to adjust settings
• Improves safety by reducing jobsite clutter

CROSSLINC™ TECHNOLOGY: SOLVING SITE WELDING ISSUES

Worker safety, weld quality, productivity and equipment reliability come to mind when welding on site or on large structures.

In these environments, it is typical for the operator to work closely with a rugged, compact and lightweight welding wire feeder, connected to a weather-resistant power source hundreds of feet away.

Worker safety, weld quality, productivity and equipment reliability come to mind when welding on site or on large structures. In these environments, it is typical for the operator to work closely with a rugged, compact and lightweight wire feeder, connected to a weather-resistant power source hundreds of feet away. Until now, portable wire feeders have been available in two configurations: basic ‘across-the-arc’ models or portable feeders equipped with an added control cable.

‘Across-the-arc’ models are powered by the weld cable. This configuration provides benefits of fewer cables running back to the power source, but voltage control at the point-of-use is not possible.

The addition of a control cable to the system allows the operator to adjust voltage at the point-of-use, but these cables can be costly and add additional complexity to the production environment.

There has to be a better way.
