It's never been easier to afford the equipment you need to grow your business.
Apply in just four minutes and get real approval in seconds - there's no hard credit pull and no documents are needed.

Benefits of Lease-to-Own Welders

A welding machine rental is great for short-term and long-term business needs. Welder leases and rentals let companies stay on top of the latest welding technology without draining their operating budget by paying upfront, in full for new machines. At the end of the lease period, you can either purchase the welding equipment outright or return it to WeldingMart. You can also buy the equipment anytime within the first year of your lease - see below for more details.

Welder rentals can also have tax benefits. In many cases, the payments you make when you lease or finance a welding machine for business or educational purposes are tax-deductible. This frees up even more resources to get the equipment, supplies and personnel that welding businesses need.

 

More Information

Welding machine financing is available 24/7 so you can apply whenever it's convenient for you. It will only take about four minutes of your time.

Once approved, you'll have the option to select the term that best fits your budget and, if approved for more than you request, our calculator makes it easy to see how your payments change for any additional items you add to your lease. eDocs are available immediately, allowing you to order your new gear within minutes.

Lincoln Flextec 650X Multi-Process Welder with CrossLinc Technology - K3425-1

 

The Lincoln Flextec 650X Multi-Process Welder with CrossLinc Technology represents a powerful and versatile welding solution designed for demanding industrial applications requiring exceptional performance and flexibility. This sophisticated welding platform delivers up to 800 amps of output power, making it ideal for large diameter wire or stick welding on thick materials across a variety of industrial sectors. The Flextec 650X combines straightforward operation with advanced capabilities, featuring simple one-knob process selection and compatibility with a wide range of available three-phase input power options to accommodate diverse workplace power infrastructures.

Engineered for reliability in challenging environments, the Flextec 650X incorporates components specifically designed to run cool for extended operational life in high-temperature settings. The system carries an IP23 rating for outdoor use in harsh environments and is Desert Duty Rated for extreme temperatures up to 55°C, ensuring consistent performance regardless of environmental conditions. The fast arc response technology delivers smooth arc action and consistent bead appearance, while user weld schedule memory storage allows easy recall of critical or frequently used welding procedures when paired with compatible Power Feed and Flex Feed 84 wire feeders. For operations requiring precise parameter control, the system offers synergic one-knob adjustment of wire feed speed and voltage when used with Power Feed wire feeders.

The Flextec 650X features Lincoln Electric's innovative CrossLinc Technology, which enables full functionality without traditional control cables, significantly enhancing operational efficiency and workplace safety. This advanced communication system allows remote procedure setting directly at the feeder, improving weld quality while reducing the need for technicians to make frequent trips to the power source for setting adjustments. By eliminating control cables, CrossLinc Technology also reduces jobsite clutter, creating a safer work environment with fewer trip hazards and cable management issues. The Flextec 650X delivers premium multi-process arc characteristics across all DC wire, stick, and Tungsten Inert Gas processes, and maintains compatibility with most Lincoln Electric feeders, including common bench and boom models, portable across-the-arc models, and CrossLinc or ArcLink-equipped systems, providing exceptional versatility for diverse welding applications.
