Here are the best benefits of the welding device.

Extreme Versatility

There are many quality welding devices in the market. Each can perform either MIG or TIG, or Flux-Core welding with the highest expected quality. Furthermore, some tools may even perform two types of welding. But Lincoln LE31MP has taken the versatility to the next level.

It can perform everything- MIG, TIG, Spool Gun, Stick, Flux-Cored, and conventional welding. Hence, professionals will get tremendous benefits from the welder. It accomplishes every welding project with an optimal accuracy level. So you get a satisfying finish.

Good Amperage Range

A good quality welding machine should be equipped with the right amperage setting. And you will get the same with the LE31MP power welding machine.

For MIG, it comes with a 30-140 AMP range, which suits medium to heavy-duty welding. The 30-140AMP amperage range also works similarly for Spool Gun and FCAW. So, you get a variety of amperage ranges with the welding device.

For TIG, it offers a 10-120 amperage range, which suits most MIG projects. Therefore, you will get quality MIG operation with it.

High Torque and Powerful Motor

The Lincoln Electric LE31MP has a stealthy motor that enables the device to provide such an extensive amperage range. Furthermore, its improved drive box mechanism brings the additional torque into play. Therefore, the machine can generate such strength and torque to accomplish every welding project.

Excellent Control

Lincoln ME31MP has excellent control with a superbly easy-to-understand panel. Lincoln Electronics have not included many knobs and switches. In fact, the whole control panel is geared with only a few controlling buttons.

So, even if you are a beginner, understanding the panel won’t be tedious for you. Furthermore, the welding machine functions with or without a paddle during the TIG operation.

But the superb control doesn’t stop here. The machine comes with an automatic detector for the paddle. Thus, when you attach the paddle, the device will detect it and adjust accordingly.

Easy Assembly

Lincoln Electric supplies the machine also preassembled. So, eventually, you are a beginner or a professional setting up the machine for the first time.

The smooth and quick setup also fastens the overall project completion. So, it is a real time-saving deal.

Variable Wire Feed Speed

The wire feed speed varies between 40-400 IPM. Hence, you will get superb control over the feed speed. Also, it is controllable with ease, which further boosts the easiness of functions.

Optimal Duty Cycle

Lincoln Electric LE31MP features a good duty cycle. It has a 60% duty cycle for MIG, TIG, and Stick, respectively, at 95A, 115A, and 80A.

This means it can continue to function for 6 minutes at a stretch and then needs 4 minutes of cooling time. Also, a higher duty cycle means you can accomplish projects in a relatively quick time.

120V Operation

Lincoln Electric LE31MP is functional with 120V output. Since 120V is a regular household output, you can easily connect the machine to a steady power source. It relieves you from the headache of worrying about the power source connection.

Isn’t it nice?

Workable on Various Materials

The welding device is usable with cast aluminum, steel, stainless steel, and other components as well. The welding depth for each time varies between 24 gauge to 5/16 inches. Thus, you get quite sufficient for each round.

Superb Transportation

Lincoln Electric LE31MP weighs only 46 pounds. For a multipurpose welding device, the weight is like a feather that enables you to transport the machine at any worksite without any issue. There’s even a quality handle mounted on the top. So, you will love taking the machine with you, especially with the gripping it provides.
