Financing / Leasing Available

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.

DETAILS

Lincoln Aspect 375 AC/DC TIG Welder - K3945-1

The Lincoln Aspect 375 - K3945-1 is an advanced AC/DC TIG welding system engineered specifically for applications demanding the highest weld quality and precision, where failure is simply not an option. This sophisticated welding platform meets the rigorous quality standards required by aerospace, motorsports, shipbuilding, education, and high-end fabrication industries, making it the definitive solution for mission-critical welds that must satisfy the most stringent testing requirements. At its core, the Aspect 375 delivers exceptionally responsive arc characteristics with remarkable stability, providing the foundation for producing the smoothest and most efficient welds possible across diverse materials and thicknesses.

The Aspect 375 embodies Lincoln's philosophy of providing both simplicity and advanced customization within a single platform. The innovative Intellistartā„¢ technology automatically optimizes starting parameters based on material thickness, delivering softer starts with minimal distortion on thinner materials while providing the hotter starts required for effective penetration on thicker sections. For aluminum applications, the optional AC Auto BalanceĀ® technology simplifies operation by automatically determining the optimal mix of cleaning action and penetration, ensuring excellent results without requiring extensive operator expertise. This intelligent automation dramatically reduces the learning curve while maintaining exceptional weld quality, making the system accessible to operators with varying experience levels.

For applications requiring precise control over specific welding characteristics, the Aspect 375 provides comprehensive customization capabilities through its sophisticated AC Wave Shape control system. This advanced functionality enables operators to precisely tailor the arc profile to address specific application challenges, including achieving deeper penetration on thicker aluminum materials, enhancing cleaning action to break through heavy oxide layers, or creating a narrower arc profile for improved control around corners and other tight configurations. The system's intuitive interface makes accessing these advanced features straightforward, allowing operators to quickly implement the exact parameters needed for their specific application requirements. This exceptional combination of automation and customization establishes the Aspect 375 as the definitive TIG welding solution for operations where quality, precision, and reliability are absolute requirements.
