Unique Features

This welder incorporates simple features with an easy-to-use design that provides accessible welding to beginners.

However, its welding capabilities and precision controls encourage more advanced users to create impressive welds with it, too.

Dual Voltage Design

The Longevity Stickweld 140 welder includes the option to run on either a 110V or a 220V input. This makes it easier to use the machine on household currents when necessary and upgrade the power when you need it most.

Variable Amp Adjustment

This setting allows users to manually enter the right amps for the job rather than relying on preset functions every time. It encourages welders to fine-tune their settings and provides precision control.

Easy Switch Over

Switching between 110V and 220V input takes only seconds with this simple and convenient design. It requires only a simple plug attachment before you can continue working.

Thermal Overload Protection

When the machine exceeds its duty cycle, it alerts the user and shuts down for a short time to cool off. When it has cooled enough, the machine becomes ready to use again.

Digital Display

The machine features a digital display that makes it easier to keep track of your amperage settings as you work.


Performance & Ease of Transportation

With an impressive performance in a relatively tiny size, the Longevity Stickweld 140 offers a pleasant surprise for home hobbyists.


The Longevity Stickweld 140 welder holds up to the performance standards of bigger, more expensive products backed by more well-known brand names.

As a solo stick welder, it provides peak performance and impressive results.

Customers enjoy working with the machine particularly on the 220V setting. However, customers report the machine overheating frequently after regular use. Pay close attention to the duty cycle to prevent this issue.

Although it lacks the running power of bigger machines, this little welder keeps home hobbyists, metal artists, and DIYers satisfied with stick welding capabilities.

Ease of Transportation

At just 23 pounds, the Longevity Stickweld 140 welder comes in at the lowest end of the portable welder size range.

It weighs considerably less than most of its competitors and provides easy transportation by simply lifting and moving it when needed.

The machine includes a built-in handle with durable reinforcements on top to make transportation even simpler.

Since it runs on household power using the 110V adapter, the machine becomes convenient to move around the home, too.


Weld Quality and Available Options

The Longevity Stickweld 140 welder regularly creates quality welds that remain smooth from start to finish. These welds hold solidly and keep up in terms of quality with many competitor stick welders.

The machine handles light to moderate welding jobs with excellent results. Customers report feeling surprised at just how much the weld quality shines with this machine, particularly given its small size.

The Longevity Stickweld 140 welding machine comes in just one option. Customers choose to add the following items to improve their welding experiences:

  • Utility cart: Use this cart to make the machine more portable and keep it wheeling easily around the garage or shop.
  • Auto-darkening helmet: For safety purposes, the auto-darkening welding helmet works exceptionally well and provides added eye, face, and neck safety.
