Welding Equipment And Industrial Supplies Financing

Welding Mart has partnered with Clicklease to provide industry-leading welding equipment for a low monthly payment customized to fit your budget. Our welder financing services allow professionals to outfit their shop with the right welding machines and systems to serve customers. Whether you need a new MIG welder, a rental TIG welder, a virtual welding training simulator or something else, rent-to-own welders from leading brands such as Lincoln Electric and Miller are a great solution.

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 Square Wave 205 TIG Welder- K5613-1

 

 

The Lincoln Square Wave 205 represents a revolutionary advancement in TIG welding technology, combining professional-grade capabilities with unprecedented user accessibility in a compact, portable package. This versatile AC/DC TIG welder delivers exceptional arc performance across aluminum, stainless steel, mild steel, and specialty alloys, making it the perfect solution for automotive restoration, fabrication shops, maintenance operations, and serious hobbyists who demand precision and control in their welding projects. The intuitive 4.3-inch LCD digital interface transforms the user experience, providing clear visual guidance and simplified navigation through welding parameters, eliminating the complexity traditionally associated with TIG welding setup and allowing both novice and experienced welders to achieve professional results with minimal learning curve.

Engineered for maximum versatility, the Square Wave 205 excels in both AC and DC TIG applications, as well as delivering exceptional stick welding performance with outstanding characteristics for both E6010 and E7018 electrodes. This comprehensive process capability allows users to tackle virtually any welding project without investing in multiple machines, creating exceptional value for small fabrication shops, maintenance departments, and serious DIY enthusiasts. The system's advanced parameter control includes adjustable pulse, AC frequency, and AC balance settings that provide precise arc control for specialized applications, from thin-gauge aluminum to heavy structural steel, ensuring optimal results regardless of material type or thickness.

The Square Wave 205's innovative dual voltage input capability automatically adapts to either 120V or 230V power sources without manual reconfiguration, allowing seamless transition between home garages, workshops, and jobsites with varying power availability. This intelligent power management system maximizes output performance based on available input power while protecting internal components from voltage-related damage, creating a truly portable welding solution that delivers consistent results regardless of location. The lightweight design, weighing just 36 pounds, features ergonomic front handles and a balanced weight distribution that enhances portability without sacrificing durability or performance capabilities.

Durability and reliability define the Square Wave 205's construction, with an IP21S environmental rating that ensures protection against dust ingress and water dripping, allowing confident operation in various workshop and field conditions. The robust internal components are engineered to withstand the rigors of daily use in both professional and enthusiast environments, while the thoughtful thermal management system prevents overheating during extended welding sessions. The integrated storage compartment provides convenient organization for consumables, torch parts, and accessories, creating a complete, self-contained welding solution that maintains workshop organization while facilitating easy transportation between locations.

Lincoln Electric's commitment to welding excellence is evident in the Square Wave 205's exceptional arc characteristics, which provide stable, smooth performance even in challenging applications like thin aluminum or out-of-position welding. The precise arc starting capabilities minimize tungsten contamination and workpiece distortion, while the responsive arc control allows for accurate heat input management when working with heat-sensitive materials or precision components. With its combination of professional-grade performance, user-friendly interface, and portable design, the Square Wave 205 establishes a new benchmark for accessible TIG welding technology, empowering welders of all skill levels to achieve exceptional results across diverse applications and materials.
