Lincoln 180 vs 140

Welding is perhaps one of the hardest professions in the world. These men and women spend countless hours bent over two pieces of metal, bearing high temperatures and intense light so that they could great things to make our everyday life easier. A welder requires several tools and equipment to be able to do what they do. The process of joining two metals or thermoplastics using high heat is not only tedious but dangerous as well. One mistake can cause painful burns that may result in permanent nerve and skin damage, not to mention how important it is for welders to protect their eyes.

Among the arsenal of a welder, the most important weapon they have is the welding machine itself. These machines produce the firepower necessary for welders to bridge the gaps between two metal surfaces for years. Welding machines produce intense heat using electricity to be able to melt metals like chromium, nickel and even titanium amongst other steels. There are exceptions, however, as to which welding machine is best for which metal as not all machines are made to support all metals. Some specialize in a few to give them the edge in the market.

Both Products have the capabilities to give you the smoothest welding with their amazing output power. Both welding machines are designed to prevent frequent splatters, therefore protecting the person who is welding. The extra-long wire helps in moving the machine around from place to place. The Lincoln 180 HD and the Lincoln 140 HD are any welder’s dream provided they understand the cost and the specialization features.

Buying Guide:

Getting your first welding machine has to be a well thought out decision because a lot of money is on the line. Good welders cost a lot and if you don’t choose them for the right specifications, you will end up regretting your decision. The right welder means it fulfills the criteria for the perfect weld in your head and physically as well. When you understand that there is no single process that is ready-made for all the different kinds of situations you may be in, you will have to be specific in what you need.

Frequently Asked Questions:

We understand you might have questions in your head regarding the two products, hence we have prepared a list. These questions will provide you with additional information that can assist you in the purchase of the right welding machine.

Lincoln 140 vs 180: Can I weld aluminum with both? Which one is more suitable?

Yes. Both products have a spool gun that allows you to weld aluminum. Welders often are met with challenges while welding aluminum since it is a better heat conductor.  
Both welding machines have the basic capabilities to weld aluminum, but the Lincoln 140 might run out of work cycle more frequently than the 180 because it has a shorter duty cycle. After this, you have to allow it to cool down. On the other hand, 180 can weld for a longer period of time. This is the only difference. The choice is yours.

Is welding stainless steel the easiest?

Stainless steel is the most common household and industrial metal in the world. It is used in your cars as well as your daily appliances that require welding works, especially pipes. The Lincoln 140 and 180 both have the capabilities to weld stainless steel in an authentic way and both provide the smooth welding experiences. Precision is important while welding as it helps to strengthen the bonds between joints, but it’s definitely not easy as it is to weld mild steel.

Are there any warranties for Lincoln 140 vs 180?

Both welding machines have a 1-year warranty provided by the company. The company believes in satisfying its customers in the best way possible and understand that certain errors can occur while using the machine which is entirely the company’s fault, that is why they cover such repairs. However, this does not mean they will mend all of the machine failures for free as some things can break because of your own mistakes. For example, if you lose some essential parts, the company cannot do anything about it and you have to spend a little extra to get the machine back working.

In terms of usage time or duty cycle, which one lasts longer?

That would be the Lincoln 180 HD. The Lincoln 140 HD is designed to be used for smaller projects that require lesser time and can burn out fairly quickly. This means the machine can become really hot really fast which is why you need to turn it off and let it cool down. This is the reason why the machine is less expensive than the 180 as it produces less power and does not have the endurance to sustain long hours of non-stop welding

Is there anything special I should know about when welding vertically or upside down?

When you’re welding 1/8″ or less metal in the vertical up, vertical down or overhead position, it is critical to watch the puddle. Remember to keep the arc on the leading edge of the weld puddle, if the puddle runs in front of the arc you will get a lack of fusion. Try reducing your voltage and wire feed speed and use a sweeping motion. For thicker material weld in the vertically up direction, and use a slight weave motion.

Does shielding gas affect the quality of the finished weld?

For most mild steel applications, CO2 will provide adequate shielding, but when you must have a flatter bead profile, less spatter, you may want to consider adding 75 to 90% argon to your CO2 shielding gas mix, you can read more about shielding gases here.
Why? Argon is essentially inert to the molten weld metal and therefore will not react with the molten metal. When CO2 is mixed with Argon, the reactivity of the gas is reduced and the arc becomes more stable. But Argon is more expensive. In production welding, selecting the perfect shielding gas can be a science of its own. Attributes such as material thickness, welding position, electrode diameter, surface condition, welding procedures, and others can affect the results.

Are there any other tips you can provide for higher quality MIG welding?

Try a smaller diameter wire. Although the most common diameters of welding wire are .035″ and .045″, a smaller diameter wire usually will make it easier to create a good weld. Try a .030″ wire diameter, which is especially useful on thin materials of 1/8″ or less. The reason? Most welders tend to make a weld that is too big – leading to potential porosity and a big bead. A smaller diameter wire welds more stable at a lower current which gives less arc force and less tendency to burn through.  
If you keep your weld current lower, you will have a greater chance of success on thinner materials. This is a good recommendation for thinner materials but be careful using this approach on thicker materials because there may be a risk of lack of fusion.
