Unique Features

The Lincoln 140 HD welder combines beginner-friendly controls and features with advanced settings for a portable solution that works for everyone.

Forgiving Arc

Featuring a forgiving arc and a smooth start, this machine allows beginning welders to dial in settings without worrying about ruining their projects. It also starts clean and cuts back on spatter significantly.

Cast Aluminum Gearbox

The cast aluminum gearbox in this machine allows it to run quietly without cutting back on any of its power.

Adjustable Drive System

Thanks to its built-in adjustable drive system, this welder cuts back on the risk of tangling and feeds wire smoothly and quickly while you work.

Wide Output Range

The wide output range provided by this machine allows advanced users to dial in precise settings and create the perfect results.

120V Power

With 120V input power, the Lincoln 140 HD welding machine makes it easy to plug into household currents and start welding in no time.


Performance & Ease of Transportation

Combining a small profile and powerful internal components, the Lincoln 140 HD welder brings MIG and flux core welding to home hobbyists.


This machine features reliable inner parts backed by the Lincoln Electric company’s commitment to excellence.

As a result, it offers exceptional durability and a long-lasting design ready for many years of welding projects.

The machine remains strong and resists damage even when used on the go. Its outer shell works to protect the interior parts from jostling and cuts down on impact while the machine operates.

With an impressive duty cycle, this machine runs for a long time without needing to stop and cool down.

It holds up well to work on mild steel and stainless steel, and with the optional spool gun attachment it even handles aluminum.

Ease of Transportation

This welder weighs 50 pounds, putting it in the middle of the portable MIG welder weight range.

Although it weighs more than some competitors, it also includes more powerful inner parts and extra features that make up for the weight increase.

This machine comes with a built-in molded plastic handle to make lifting and carrying easier.

Since it hooks up to household power currents, it travels well around the home or garage and works for on-site professional jobs, too.


Weld Quality and Available Options

Despite its lightweight, small size and 120V input power, this machine regularly surprises customers with its ability to truly weld.

When used as a flux core welder, it really shines, but the machine also provides MIG welding functions beautifully too.

This welding machine runs hot enough to create smooth welds from start to finish.

It offers a smooth start that prevents spatter and keeps welds solid and clean from beginning to end. Even beginners produce professional-quality welds when using this welder.

Although the Lincoln 140 HD welding machine comes in just one option, customers frequently add the following:

  • Utility cart: This machine remains lightweight enough to carry but works better for portable purposes when installed on a utility cart.
  • Magnum Pro 100SG Spool Gun: A spool gun attachment makes aluminum welding easier on this machine.

Ease of Maintenance, Repairs & Warranty

The Lincoln Electric company makes it easy to find replacement parts for this and other welders.

The company’s web site offers a serial number lookup that matches parts to machines so customers can order replacements as needed.

The company recommends contacting a licensed repair technician to handle internal component repairs.

However, customers can and should perform routine maintenance on this machine.

To do this, start by unplugging the machine and leaving it alone for 30 minutes to discharge for safety. Next, remove the front cover but leave the fixed side intact. Do not open the fixed side.

Use compressed air to clean out the internal accessible parts of this machine as well as its vents. Clean the inside of the MIG gun and its liner with compressed air, too. Do not take the fan or fan motor apart.

Vacuum dust and debris from the wire feed compartment and gearbox, and check tubes and connectors.

Replace any damaged or worn connectors, cables, tubes, and consumable parts. Perform this maintenance every 1 to 3 months as needed.

The Lincoln Electric company provides a limited warranty to cover problems with this welder.

The warranty covers issues with damage or malfunctioning parts caused by the manufacturer but excludes damage caused by user error or improper installation.

The warranty provides three years of coverage for the welder and wire feeder as well as one year of coverage for the MIG gun and optional spool gun attachment.

It includes a 30-day money-back guarantee for consumables and other expendable pieces.

Contact the Lincoln Electric company’s warranty department for more information at 888-935-3877.
