lincoln 140c vs 180c (Everything A Welder Needs To Know)

Any small project that involves metal welding requires a versatile welder. And Lincoln remains a trusted name among the pros and amateurs alike.

Simple MIG or Flux-Cored welding doesn’t require an expensive purchase. Lincoln has top-class welders like 140 and 180 to make both ends meet.

But they share many similar features from the inside and the outside. This often gives buyers headaches while purchasing the ultimate welder.

Knowing Lincoln 140 vs. 180 can resolve all the problems and confusion. And we have the perfect hand-in-hand comparison right here for you.

Let’s start with the tabulated side-by-side comparison between the welders.

Pro MIG 140 vs. Pro MIG 180

There are many technical differences exist between the two welders. Still, there’s more to know aside from the side-by-side comparison. Take a look at the products individually for a better understanding.

Lincoln Pro MIG 140

The compact machine is indeed a great choice for light welding tasks. You can use the welder for home and garage uses with its 120V rating. Also, make the device suitable for other outlets with an adapter.

It delivers gasless flux-cored and gas-shielded MIG welding. The former process gives deep penetration into thick steel materials. And the MIG process enables precise welding on thinner metal sheets of steel.

Its compact size contributes to the overall lightweight portability. You can take the welder anywhere, anytime. Even the fully assembled device with all the included accessories can’t give you any trouble.

Std brass-to-brass connection delivers improved conductivity. You can make easy changes to polarity to switch between MIG and Flux. It even comes with an instruction manual and MIG weld DVD for guidance.

Pros and Cons

Lincoln Pro MIG 180

Pro 180 is more like an upgrade of Pro 140 in terms of functionality. However, the primary features are almost the same. You can apply somewhat superior weldability on any home, shop, or farm project.

It’s a dual voltage device to support standard 230V and a slightly non-conventional 208V. That’s where the welding current tends to vary. Nonetheless, you can make it suitable for outlets using an adapter.

A smooth arc start ensures a precise outcome without splatters. Its drive system adjustment eliminates the chances of crashing and tangling. The MIG process can weld thin sheets of steel/metal in a single pass.

Necessary accessories are available within the package. But you may have to purchase some extra gears for the optimum experience. Either way, it remains compact/lightweight enough to ease hand carriage.

Pros and Cons

Lincoln 140 vs. 180: Similarities

Welding:

Either one performs only two common types of welding process – MIG and Flux-Cored. And you can utilize the process for light works only. Neither product can handle heavy or frequent loads.

Speed:

Wire feeding speed remains the same as one another. The speed rate counts as 50” – 500” or 1.3m or 12.7m penetration per minute. So, you won’t receive any particular benefit from either one.

Wire Drive:

The featured drive system is fully adjustable on both units. The numeric drive tension indicator can identify wire diameter ranges. You can turn the knob comfortably to adjust the drive.

Gearbox:

Even the gearbox shares a similar size, function, and frame material. The cast aluminum box adds up to the driving torque. Also, either machine appears notably silent with a minimal noise level.

Welding Arc:

Both welders deliver a forgiving arc to make the application easy. You’ll have smooth arc starts with no splatters. Their MIG process can weld sufficiently thick metal sheets with a single pass.

Accessories:

Crucial ones are already present in the box for your instant setup. Either one includes shielding gas apparatus, guns, and welding wire. And all their specs have the exact technical details.

Lincoln 140 vs 180: Differences

Size/Weight:

Physical dimensions are somewhat smaller in 140 than in 180. That’s why the assembled weight of 180 is higher than 140. However, the masses are close enough to give no big differences.

Input Voltage:

140 requires a steady 120V input to initiate the arc. But 180 can work with either 208V or 230V. Not to mention, using a suitable adapter can make both systems work with common outlets.

Rated Output:

The range of output current is 30A – 140A for 140. But it’s slightly broad for 180 with a 30A – 180A range. However, output voltage seems to share no similarity between the two with variable ratings.

Max OCV:

Zero amperage or no arching voltage slightly differs in the two. Pro 180 delivers a maximum of 34V for OCV. Meanwhile, Pro 140 delivers a close 33V to hold sufficient similarity while there’s no arc.

Performance:

Welding outcome appears slightly better in 180 compared to 140. Further output current contributes to the precision level. Still, you can obtain excellent precision with 140 on metal sheets.

Frequently Asked Questions

Wrapping Up

Pro 180 seems to outmatch its predecessor 140 in several aspects. Its dual voltage remains the most prolific advantage.

But either one can deliver satisfactory welding performance to a certain extent.

Even the prices look justified for the integrated features for both. You just need to pick the ultimate one based on your needs.
