As far as the structure of these welding machines is considered, both of them are outstanding and can be used to carry out easy household work. For the price, the Lincoln 140c will provide you better structure and is more unique than Lincoln 140HD. It is made up of solid metal and has a good body. Therefore when it comes to solid structure and functioning, no doubt Lincoln 140c got a plus point here. Also, have a look at the Lincoln Pro MIG 180 review.


Performance is an important factor that you will need to notice initially regarding these welding machines. Lincoln 140c is way better in performance and gives smooth and better outcomes than Lincoln 140HD. It has a specialized technology known as diamond core technology, and it comes with enhanced torque.

It is used for doing heavy welding projects that are not done daily. Apart from that, Lincoln 140HD is best when it comes to the beginner level. If you are new to welding, then lincoln 140Hd will work perfectly for you, and if you are a professional, you can easily go with lincoln 140c.

Weight and Portability

The weight of Lincoln 140c is 58 pounds, whereas the weight of Lincoln 140 HD is 50 pounds. This also explains the weight of the highly constructed material used for Lincoln 140c. Another thing that is linked to weight is the portability of the welding machine.

As Lincoln 140 C is bulkier in weight than lincoln HD, it simply means that it is easy to move lincoln HD while difficult to move Lincoln 140 C with the same amount of energy. Hence the crown for lightweight and portability goes to Lincoln instead of Lincoln 140 HD.


Power is one of the major factors seen in welding machines as it determines the excellence of welding that can be done by using it. Both machines give 140 amp, which is the highest value when the input of 20 amp is provided. The duty cycles of both welding machines are 20%. Therefore there is no difference between both welders.

There are specific knobs that are present on the body of the welder. These knobs play a basic role in setting the voltage. If you are using 140c, you will need to rotate the knob anywhere from A to J. There will be no fluctuation, and you will be able to work without stopping. Whereas in the case of 140HD, you will need to rotate the knob and set it to the desired level where you think it would work finely.

Dimensions and Design

Both machines are designed beautifully. The dimensions of Lincoln 140c are ‎18.6 x 10.15 x 14 inches, whereas the dimensions of Lincoln 140 HD are‎ 18 x 15 x 16 inches. Both of the welders are DC-based with a voltage capacity of 120 V and 110 V, respectively. The design of both machines is the same, and no major difference is present in these welders.

They appear to be completely identical when it comes to outer appearance. But the functioning of both is very different. A small difference that you will observe in both of these welders is the presence of a protection board in lincoln 140c, but there is no board in lincoln 140 HD. This means that the lincoln 140 c is more protective than the HD one.


Both of the welders come with their proper accessories. These accessories help to give them a break-free start and provide extra smooth welding. A spool of wire is provided. Lincoln 140 HD can provide .025 to .035” of wire, while the range of wire that Lincoln140c can hold is also the same. Lincoln 140 HD includes magnum 100l, while magnum pro is present in lincoln 140c.

Speed Feed Range

The speed feed range present in both of the welders is different. The speed present in Lincoln 140c is 50-500 IPM, whereas the speed present in Lincoln 140 HD is slightly different as it can weld the 5/16 thickness of the metal sheet. This increased speed indicated that Lincoln 140 HD has more speed and capacity for welding than other metallic welders and Lincoln 140c. Therefore Lincoln 140 HD is best when it comes to speed feed range.


This welder comes with increased usability, and you can use Lincoln 140HD for maximum working and welding, whereas Lincoln 140C comes with moderate usage. You can use Lincoln 140 HD if you have prolonged working hours and Lincoln 140c if you work a few times or use it once in a while. Another interesting difference between Lincoln 140c and Lincoln 140HD welding machines is that Lincoln 140c is pretty quiet with its working while Lincoln 140 HD is pretty noisy when it comes to functioning.
