Lincoln Electric’s Flextec 650X


The Flextec® 650X multi-process welder from Lincoln Electric® gives operators full functionality and control at the arc without an added control cable, thanks to embedded CrossLinc® Technology.

The Flextec 650X expands upon the well-established and proven Flextec 650 platform. Like its predecessor, the Flextec 650X is rated at 650 amps, 44 volts at 100% duty cycle. It delivers up to 815 amps for heavy applications or a stable arc at low currents for MIG or TIG welding on thin materials. Typical applications involve heavy fabrication.

It’s ideal for large-diameter stick, flux-cored, MIG or submerged arc welding on thick materials and is also capable of gouging with up to a ½ inch (12.7 mm) carbon. The 650X yields a fast arc response, smooth arc action and smooth bead appearance on all DC wire, stick and TIG processes.

Using CrossLinc, the Flextec 650X now enables remote control of procedure settings at the arc.  This leads to improved weld quality and increased productivity by reducing trips to the power source. It also improves safety by reducing jobsite cable clutter. With the Flextec 650X, CrossLinc can be used with an LN-25X feeder for wire fed welding processes or the new CrossLinc® Remote for Stick, TIG or gouging processes.

With the addition of ArcLink, Lincoln Electric’s digital communications protocol, the Flextec 650X can be used with an expanded list of wire feeders compared to the previous 650 model. Applicable feeders include weld schedule memory storage to give operators easy recall of critical or often-repeated weld procedures.
