OVERVIEW

Industrial Power and Intelligence Combined

The Lincoln Electric Flextec 500X Multi-Process Welder is engineered to deliver powerful performance in the most demanding industrial environments. Designed for versatility, this 500-amp power source handles a wide array of welding processes including MIG, TIG, Stick, Flux-Cored, and Carbon Arc Gouging. Whether you are working in a shipyard, on a construction site, or in a heavy fabrication shop, the Flextec 500X provides the reliability and output required for heavy-duty applications.

CrossLinc Technology: Control at the Arc

One of the standout features of the Flextec 500X is its integrated CrossLinc technology. This innovative system allows for full remote control of the power source directly through the welding leads, eliminating the need for fragile and expensive control cables. By enabling voltage and amperage adjustments at the wire feeder hundreds of feet away, CrossLinc improves weld quality, increases arc time, and enhances safety by reducing cable clutter on the jobsite. It also features True Voltage Technology (TVT), which automatically compensates for voltage drops across long welding cables to ensure the delivered voltage matches your settings.

Built for the Harshest Environments

Reliability is paramount in outdoor and industrial settings. The Flextec 500X boasts an IP23 rating, ensuring it is protected against water spray and foreign objects, making it an excellent choice for outdoor construction and field erection. Furthermore, it is "Desert Duty" rated, capable of operating at full capacity in extreme temperatures up to 55°C (131°F). The internal components are equally protected; PC boards are trayed and potted to shield sensitive electronics from dust, moisture, and vibration. The unit is housed in a durable, powder-coated aluminum case with shock-absorbing rubber feet and heavy-duty alloy handles.

Advanced Process Capabilities

Beyond standard CV and CC modes, the Flextec 500X is ArcLink enabled. When paired with a compatible digital wire feeder, it unlocks synergic pulse MIG modes for superior welding on steel, stainless steel, and aluminum. The machine also offers optimized stick welding modes for both cellulosic and low-hydrogen electrodes, as well as Touch-Start TIG for easy, contamination-free arc initiation without high frequency. This flexibility makes the Flextec 500X a truly universal power source for modern industry.

FAQ

CrossLinc Technology allows the power source and wire feeder (or remote) to communicate directly over the copper welding leads. This enables voltage and amperage control at the arc without requiring an additional control cable, reducing clutter and setup time.

Yes, the Flextec 500X has basic pulse MIG capability standard. However, to fully utilize synergic pulse modes for materials like aluminum or stainless steel, it must be paired with an ArcLink-compatible wire feeder.

The Flextec 500X K3607-1 is a 3-phase machine that accepts input voltages of 380V, 460V, or 575V at 50/60 Hz.

No, the Flextec 500X is a DC-only power source. It can TIG weld steel and stainless steel, but it cannot TIG weld aluminum, which typically requires AC output.

Yes, the machine has an IP23 rating, which protects it against water spray and foreign objects. It is also 'Desert Duty' rated for operation in temperatures up to 55°C (131°F), making it ideal for outdoor construction sites.

The machine is rated at 500 Amps / 40 Volts at 60% duty cycle, and 450 Amps / 38 Volts at 100% duty cycle.

No, the K3607-1 includes the power source only. Wire feeders, welding guns, and cables must be purchased separately or as part of a Ready-Pak.

The Flextec 500X features optimized stick welding modes specifically designed for both cellulosic (e.g., 6010) and low-hydrogen (e.g., 7018) electrodes.
