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.

Lincoln Aspect 375 AC/DC Low Hour Factory Demo TIG Welder - U3945-1

 

 

Compare to New Aspect 375 - K3945-1

Factory 3 Factory Warranty

 

 

The Lincoln Aspect 375 AC/DC represents the pinnacle of professional TIG welding technology, specifically engineered for mission-critical applications where weld quality is absolutely paramount. This premium system delivers exceptional performance for industries with the most demanding quality standards, including aerospace, motorsports, shipbuilding, education, and precision fabrication. As a low-hour factory demo unit, this Aspect 375 offers an outstanding opportunity to acquire Lincoln's flagship TIG technology with minimal previous use at enhanced value while maintaining the reliability necessary for applications subject to rigorous testing requirements.

At the core of the Aspect 375's superior performance is its remarkably responsive and stable arc characteristics, which provide the most efficient and smooth welding experience possible across diverse materials and thicknesses. Lincoln's innovative IntelliStart technology automatically optimizes start parameters based on material thickness, providing softer starts with minimal distortion on thinner materials while delivering the higher heat input required for thicker workpieces. For aluminum applications, the optional AC Auto-Balance technology further enhances performance by automatically determining the optimal balance between cleaning action and penetration, simplifying operation while maintaining exceptional results.

What truly distinguishes the Aspect 375 is its unparalleled level of customization capability when precision control is essential. The comprehensive AC Wave Shape control system enables operators to fine-tune every aspect of the welding arc, including frequency, balance, and offset parameters. This precise control allows optimization for specific aluminum welding challenges, whether the priority is achieving deeper penetration on thicker materials, increasing cleaning action to break through heavy oxide layers, or creating a narrower arc profile for enhanced control in tight configurations. With its robust 375-amp output capacity and versatile input power compatibility (200-600V), the Aspect 375 delivers the performance, flexibility, and reliability required for the most demanding TIG welding applications across multiple industries.

 

 

Key Features

 

 

  • Effortless arc control for the smoothest welds
  • AC Auto-Balance makes it simple by automatically providing the optimal mix of cleaning and penetration on aluminum
