Powerful Performance From the Ground Up - Out in the shipyards, construction sites and fabrication shops, it pays to keep it simple. The Flextec 500X multi-process welder is easy to set up and operate, yet rugged enough to stand up to heavy-duty indoor and outdoor applications.
Compare to New Flextec 500X - K3607 - Full 5 Year Factory Warranty
The Flextec 500X delivers exceptional simplicity with its straightforward interface for ease of use and CrossLinc technology that eliminates extra cables for simple system setup. Basic pulse MIG capability is standard on the Flextec 500X, including weld modes for carbon steel, stainless steel, aluminum and metalcore electrodes. The unit features an IP23 rating that means the Flextec 500X welder will excel in outdoor environments, such as construction sites and shipyards, while being Desert Duty® rated for operation in the harshest environments up to 55°C (131°F). Durable trayed and potted PC boards provide electronics environmental protection for long-lasting reliability in demanding conditions.
The Flextec 500X offers exceptional flexibility as a multi-process power source for all your welding needs. It's compatible with all 42VAC wire feeders for MIG and Flux-Cored welding and features ArcLink® enabled power source that provides synergic pulse modes. CrossLinc allows for remote control of CV and CC processes without extra cables, giving you the flexibility to control the machine from hundreds of feet away without a control cable. The unit delivers optimized stick welding for both cellulosic and low hydrogen electrodes and Touch-start TIG for easy, contamination-free starts without high frequency. With CrossLinc Technology compatibility providing full functionality without control cables, the Flextec 500X enables remote procedure setting at the feeder to improve weld quality, increases arc time with fewer trips to the power source, and improves safety by reducing jobsite clutter. Ideal for cross-country pipeline, construction and field erection, general fabrication, heavy equipment, heavy fabrication, and structural fabrication applications, the Flextec 500X represents the perfect balance of power, reliability, and advanced technology backed by a comprehensive 5-year warranty.

The Flextec 500X supports MIG (GMAW) and flux-core (FCAW) welding as primary processes. Multi-process models in this family may also support Stick (SMAW) and DC TIG (GTAW). Check the spec sheet for full process compatibility for your specific unit.
Most Lincoln Electric MIG welders in this class accept .023", .030", and .035" solid wire, and .030"–.045" flux-core wire. Some heavy-duty models accept up to .052" wire. Always refer to the owner's manual for the wire size and drive roll requirements specific to your model.
Duty cycle and output amperage vary by model. Lincoln Electric MIG welders in this range typically offer 100–350+ amps of output. Duty cycle at maximum output is listed in the spec sheet — higher-tier industrial models run at 60–100% duty cycle at rated amperage for continuous production welding.
Input power requirements depend on the specific model. Smaller MIG welders (140–215A class) typically run on single-phase 120V or 240V. Larger industrial machines (260A and above) may require single-phase 240V or three-phase 208/230/460V. Check the spec sheet for the exact input power requirements for your unit.
Yes — this is a factory demo or low-hour unit sourced directly from Lincoln Electric. Units may show light cosmetic wear but are mechanically sound and have been tested before sale. Contact WeldingMart for information on any remaining manufacturer warranty for your specific unit number.
For solid wire MIG welding, a 75% Argon / 25% CO2 (C25) mix is the most common choice for steel. 100% CO2 is also used for cost-sensitive applications. Flux-core wire can be run with or without shielding gas depending on the wire type. TIG welding (if supported) requires 100% Argon. Always confirm gas requirements in the owner's manual.
