1. Performance

Lincoln 140C is designed to be used for heavy-duty welding projects. Since this machine includes diamond core technology and drives motor with enhanced torque, the performance is slightly better, and smoother compared to 140HD. 

On the contrary, Lincoln 140HD is a beginner friendly welder. The package comes with a fully adjustable drive system that reduces the chance of wire tangling and crushing. This unit performs fast, easy and not so heavy welding tasks on thin materials.

Both the machines provide an output amperage of 140 amps (max) when the input amperage is 20amps. (Read more about Miller 141 Vs 211: Which Is Really Better)

2. Usability

By using 140C you can weld stainless and mild steel, having material thickness of 1/4″. With the ready-to-use spool gun, welding aluminum is not a bother anymore. And with the spot timer, the machine serves with splendid welding on thin metals also.

Now, 140HD can be used almost anywhere. This is an excellent choice for both gasless flux-cored welding on thicker steel and gas-shielded MIG welding on thin gauge steel. Moreover, stainless or aluminum can be welded as well.

3. Portability

Lincoln 140C Product dimensions: 18.6 x 10.15 x 14 inches

Lincoln 140HD Product dimensions: 18 x15 x16 inches.

Both the machines weigh 71 pounds. This might seem a bit heavier for users. So, it is recommended to use a cart to move from one place to another. (Read Lincoln 140 Vs Hobart 140 post).

4. Power features

Both the machines can run smoothly with 120V power.

The bulb voltage of 140C is 76 volts. Here, C stands for Continuous Volt control; you can set the voltage to anything on the dial from A to J voltage control knob which allows expert welders to weld certain thickness of metals.

On the other hand, 110 volts is the bulb voltage of Lincoln 140HD. This welding machine introduces the user to an easy to understand (A, B, C, D) voltage knob to control the outer ampere. (Read in detail comparison Hobart Vs Lincoln).

5. Capacity and type

Lincoln 140C is equipped with tough metal wire feed drives, which are 50 to 500 inches per minute flexible. With this wire feed, it can MIG weld from 24 gauges up to 10 gauge sheet metal in a single pass. And this machine can weld up to 5/16” thick metal steel using the self-shielding Lincoln inner shield wires.

Duty cycle percentage: 20%

On the other hand, 140HD can MIG weld 24 gauge up to 3/16 in. sheet metal in a single pass. And since it uses electric wires, it can weld up to 5/16 in.

Duty cycle percentage: 20-40%.

Frequently Asked Questions (FAQs)

1. What is the equivalent in volts of the A-B-C-D scale?

Answer: The A-B-C-D scale means low, medium low, medium high and high.

2. How is conductivity enhanced in Lincoln 140HD?

Answer: There is a high conducting brass-to-brass gun connection included in 140HD. This system ensures extended safety and enhanced conductivity.

3. What is the difference in PC boards on 140C and 140HD?

Answer: 140HD has an open PC board that requires a fan or other cleaning tools to remove dust whereas 140C has a built-in closed PC control board which secures the equipment from dirt.
