Lincoln Electric Weld Pak 140 HD View from the Top Down

The Lincoln Electric Weld Pak 140 HD K2514 MIG welder is an easy to use and flexible welder. But wait.

The welder is known by and is sold under a few different names;

  • The Pro MIG 140
  • The MIG Pack 140
  • The Easy MIG 140

Same welder different names. More on that later.

The input power of 115V means these welders are for those light to medium welding jobs. These little red corvettes of welding are able to use both flux core and solid wire with shielding gas.

The question of the day is;

Should you get one?

  • check
    ​The Lincoln 140HD MIG welder will weld Aluminum using its optional Magnum 100SG spool gun

Cons of the Lincoln 140HD MIG Welder

  • ​​You pay a bit more for the Lincoln Electric brand name. Here ​quality comes with a price tag
  • Times
    ​​ A stepped dial between A - D makes it difficult to gauge your welding output amperage. More sophisticated welders may find that frustrating.
  • Times
    ​​No mention of stainless steel welding or the ability to use Tri-Mix gas. Want to weld stainless steel then perhaps look elsewhere

​Verdict  on the Lincoln Weld Pak 140 HD

The Difference Between Lincoln 140 Welders

My readers seemed to be interested in the differences between the many Lincoln 140 welders and for good reason. The number of 140 MIG welders Lincoln Electric has is kind of confusing. Let me help to clear up the confusion for you.

There is the:

The Lincoln 140HD Weld Pak

Lincoln 140 Pro MIG welder

Lincoln 140 MIG Pak

Lincoln 140 Easy MIG welder

 Yes, there are quite a few. Let me show you how the Lincoln 140 spec's compare.

So what is happening here? Why do all these Lincoln 140 spec's look the same?

I'll tell you read on…

​The Weld Pak 140 HD and the Pro MIG 140 and the …. ?

It's confusing. Why does Lincoln have so many MIGs with the same specifications with dissimilar names?

It becomes clearer when you realize that Lincoln Electric distributes this welder in a number of guises depending on their distribution partner. Amazon, Lowes, Sear's, Home Depot etc.

You'll see the little red welder as the Lincoln Weld Pak 140 HD as I've described it here in this post. You will see from the comparison chart above the Pro MIG 140 is the same set up. You'll also see it sold as the Easy MIG 140.

Or direct on as the Lincoln Electric site the MIG Pak 140.

Why? Well it enables each of their distribution partners to sell under their own brand. So for example:

The HD part of the name defines the Lincoln Weld Paks that are typically sold under the Home Depot brand name and you can also get those welders on Amazon.

The review you read here is valid for them all and I'll use the names interchangeably throughout the article.

Cause what they call it really doesn't matter. They are all the same.  

Readers were also interested in how the Lincoln HD 140 compares to it's smaller and less expensive brother the Lincoln Electric Handy MIG.

That spec comparison is later on down the post. Use the​ link to jump straight there to see that now.

Review and Overview of the Lincoln Weld Pak 140 HD

The Lincoln 140 Weld Pak is aimed both at the welder who is starting out on their MIG welding journey as well as the more experienced welder looking for a solid MIG welder that is portable and convenient to use.

Built for light welding tasks such as straight forward repairs around the home and yard. It is also portable enough to be taken to a repair out in the field or farm.

Cooled by an internal fan the Lincoln Electric 140 HD Weld Pak needs decent clearance front and back to allow the fan to do its job and keep this little red nice and cool.

The Lincoln 140 HD Duty Cycle

Those in the know realize one of the first things you want to know about a welder is its duty cycle. How long can you weld for and at what Amp, it tells you a lot about what a welder is capable of.

The Lincoln 140 HD duty cycle at 20% @ 90 Amp voltage output, makes it a decent welder though not one built for heavy welding tasks.

Remember that the:

  • Lincoln Pro MIG 140
  • And the Lincoln 140 MIG Pak
  • Lincoln Electric 140 Easy MIG.

Are the same machine, so all their duty cycles are exactly the same as the Weld Pak 140.

What Does the Lincoln 140 HD Duty Cycle Really Mean?

Let me explain For those new to welding.

The duty cycle means that when you are using the 140 Weld Pak over a ten minute period, you are able to weld for 2 minutes. That is what the 20% stands for.

The 90 Amp part of the duty cycle is the maximum defined amperage for that 10 minute welding cycle. 

Keep in mind that the welder is capable of welding at a higher 140 Amp setting. Running the Lincoln Electric 140 HD welder at its maximum capable output of 140 Amp means that your welding time would be much shorter.

Once you have breached the duty cycle, you will need to leave the welder to cool for 8 minutes. 

Netting this out.

If the welding tasks you have in mind are thicker 1/4 inch steel or 5/16ths steel. You will have less than 2 minutes continuous welding time with the Lincoln 140. Probably much less.

And if that is what you are mainly going to weld then the Lincoln 140 K2514 will be too small a welder for you.

Lincoln 140HD MIG Welder Controls

Simple to set up and use the Weld Pak 140HD has the on/off switch at the front.

There are two dials. One for setting your welding output voltage and the other for the wire feed control. These are also on the front of the unit. 

Pro Mig 140 dials

Pro MIG 140 dials

​The thermal trip protection light is there too and will signal when the Lincoln 140 duty cycle has been exceeded.

Looking for some other options for a beginner MIG welder?  You can always take a peek at a MIG comparison here on the site.

The Lincoln 140HD Weld Pak's Protection from Over Heating

The Lincoln Electric Weld Pak 140 has inbuilt protection should you exceed the duty cycle.

Here is why?

It is to prevent your welder from terminal damage through over heating. The inbuilt protection will stop the Lincoln 140 HD welder from welding and the light on the front will come on.

Should this happen do not switch off the power to the Lincoln Electric 140 Weld Pak. ​Turning off the power will turn the fan off.

The fan will need to run until the Lincoln 140HD welder has returned to a safe operating temperature. Once this happens the thermal protection will reset automatically, however there is a circuit breaker on the back which will pop out and will need to be reset manually.

Lincoln 140 MIG Welder Settings

For those novices to welding machines I'll just quickly explain that the welding power of a welder is measured by its voltage output.

The output voltage on the Lincoln Weld Pak 140 HD is set via one of the dials on the front.

Weld Pak 140 front dials and On Off Switch

Weld Pak 140 front dials and On Off Switch

The Lincoln Electric 140 HD welder has a welding output of 30 to a maximum 140 Amp across the four voltage settings.

The dial is a tapped dial with output settings from A to D in four welding voltage output settings.

What does that mean?

It means that you only have those settings and cannot set the dial between the dial settings.

For example you cannot set the Lincoln 140 HD in the middle of B and C for example.

This makes the Lincoln Weld Pak 140 easy to use but not for those who like to vary their welding output more finely than that.

The other thing is that you can't easily match the Amp output to the dial. Why does that matter?

Resources available on the web may say for this gauge of metal and type of metal it is best to set your welder at a particular amperage. Say 60 Amp.

​But is that dial setting B or C or neither? You have to use the welder settings chart on the cabinet as your source for the right output settings.

Lincoln 140 MIG Welder Settings Chart

How do you use the Lincoln 140 MIG welder settings?

The Lincoln Weld Pak 140 HD has a welding chart on the inside of the cabinet door. The chart details the suggested setting A through to D on the output dial for …

  • the type of metal your welding (mild steel or Aluminum)
  • the thickness of metal you are welding
  • the wire they recommend you use, whether it is flux core or as a MIG using solid wire and shielding gas
  • the wire speed for the type of wire you are using on the Lincoln Electric Weld Pak 140.

Unfortunately this chart is not printed in the Lincoln 140 HD manual you get with the welder. So should you damage the chart on the inside of the cabinet door you may find yourself struggling.

For those who would like to see the chart ahead of purchasing or if you have damaged yours I've a couple of images taken close enough for you to see the details that should help.

YouTube How to Set Up a Lincoln MIG Welder

In this YouTube video, Lincoln Electric has put together an overview for getting started with welding. It is not only a useful introduction to the Weld Pak 140HD it is a primer on the basics of welding well.

Enjoyed the video? Lets continue with the quest to find out whether you should get a Lincoln Electric 140 MIG welder.

What Type of Metals and Sizes can the 140 HD Weld Pak Weld?

Mild Steel

The Lincoln 140 HD welder is able to weld metal sizes from 24 gauge through to 3/16th of an inch in a single pass. 

The Lincoln Electric Weld Pak 140 HD can even go up to 5/16th of an inch, though welding 1/4 inch to 5/16ths will require multiple passes with this welder and the use of flux core wire. 

If you are looking to weld car panels thinner than 24 gauge you will need to have a skilled light hand or risk blowing through the metal. Perhaps not something for a beginner's project with this welder.

Aluminum

The Lincoln Electric 140 HD Weld Pak will weld 22 gauge to 10 gauge Aluminum using the optional Magnum 100SG Spool gun.

Stainless Steel

​There is no mention of the Weld Pak 140 welding stainless steel.

Achieving Better Welding Penetration On Mild Steel With the Lincoln HD 140

On the Lincoln 140 MIG welder settings chart they recommend flux core welding wire. In particular their Innershield brand name wire for welding 1/4 of an inch to 5/16th of an inch mild steel.

Flux core welding wire is well known for achieving better weld penetration on thicker steel. Although it can produce more welding spatter.

 Not sure what spatter is? I have a document about it here.

The Power Requirements of the Lincoln 140HD Weld Pak

Welding in the Home Garage?
Convenient to use the Lincoln Weld Pak 140 HD needs 115 volt input and uses a normal 3 pin household socket with an earth. 

You will need a 20 Amp fused circuit as a minimum.

To use this 140 HD welder at its maximum output a 30 Amp fused circuit with a good earth is recommended. 

Either way don't be tempted to drive anything else of significance on the same circuit as the Lincoln 140 HD MIG Welder.  That will take away the available power to your welder and will affect the quality of your weld beads. And you may have trouble even striking an arc.

​The Lincoln Electric Handy MIG is also a flux core wire welder and will use solid wire and shielding gas. It's a little lighter, not quite as powerful, but could be an option for you if you are not planning to weld Aluminum.

You may want to take a look at my Handy MIG article here on the site and see what you think.

Curious to delve into the differences between flux core welding and MIG welding? I have an article that explains all.

What Welding Wire Sizes Does the Weld Pak 140 Use?

The Lincoln 140 HD uses 0.030 to 0.035 inch flux cored wire.

Or 0.025 to 0.035 inch solid steel wire.

The Lincoln Weld Pak 140 HD will use 0.030 inch Aluminum wire.

You can use reels of welding wire two pounds (four inch) or ten pounds (eight inch) in size. The Weld Pak 140 is supplied with an adaptor so that you can fit the larger wire spools.

This is great as you can take advantage of the cheaper cost per pound of the 10 lb. or 11 lb. spools.

Looking for mild steel MIG welding wire for your Weld Pak K2514? I have an article that lists the best. ​

Or searching for flux core wire for mild steel I go into all the details here. ​

Or some Aluminum wire? Check out my article here. ​

The Wire Feed Drive System on the 140 Weld Pak

The Lincoln Electric Weld Pak 140HD has an Aluminum drive system.

A good wire feed drive system is one of the most important points on a MIG welder as poor wire feed will ruin your weld.

The drive system is solid and sturdy and designed to prevent crushing or tangling of your wire feed. The quality of the wire drive system makes it clear that here you are not looking at some plastic cheap import.

Lincoln Electric 140 HD Drive System

Lincoln Electric 140 HD Drive System

The wire feed speed control is variable using the wire feed dial on the front of the unit. Speed selection is between 50 to 500 inches per minute.

What Shielding Gas Can the Lincoln Electric 140 Welder Use?

Using the Lincoln Electric Weld Pak 140 HD as a MIG welder will see you swapping to solid wire and getting a tank of shielding gas.

The chart on the inside of the Lincoln 140 HD welder's cabinet door shows the recommended gas for the type of metal you are welding.

The Weld Pak 140 HD can use a standard 75% Argon and 25% Carbon Dioxide mix for mild steel

Find more information about shielding gases for MIG welding mild steel here.

or 100% Argon for welding Aluminum

The Weld Pak 140 will also use 100% Carbon Dioxide.

The Lincoln Weld Pak 140 HD is supplied with a dual gauge Harris gas regulator. Which is a good quality regulator for feeding your gas. It is designed to feed Argon gas mixes only. 

You will need to purchase a regulator designed for Carbon Dioxide if you want to run CO2 gas.

There is no mention of the Weld Pak using Tri-Mix gas. Tri-Mix is used for MIG welding stainless steel.

Changing Welding Polarity

As is usual you will need to also change polarity when moving from flux core to solid wire and shielding gas.

Changing the polarity from positive to negative is easy on this welder and is the simple swapping of terminals on the inside of the cabinet.

Welding Aluminum with Lincoln 140 MIG Pak

Lincoln 140 Spool Gun

Yes you can weld Aluminum using the Lincoln 140 Aluminum spool gun.

The compatible Aluminum spool gun is called the Magnum 100SG and it is an optional extra and

  • MIG Pak 140 spool gun?
  • Lincoln Pro MIG 140 spool gun?
  • Lincoln Easy MIG 140 spool gun?

The Magnum 100SG spool gun will work for them too.

As they are all the same welder just marketed under different names.

Aluminum is a soft metal and trying to weld it without the Lincoln 140 spool gun is just asking for trouble and risking a rat's nest of tangled wire.

Here is a link to Amazon link where you can find the spool gun.

Capabilities of the Lincoln MIG 140 Spool Gun

The spool gun can handle 1 lb. spools of 0.030" or 0.035" Aluminum solid wire. You will also need the matching sizes of contact tips.

Choose contact tips designed for MIG welding Aluminum. As they will accommodate the Aluminum welding wire and expand correctly as the contact heats.

And to weld you will need a tank of pure 100% Argon gas mix.

Set the polarity for MIG welding and then you're great to weld.

The little red Lincoln 140 MIG welder can weld Aluminum from 22 gauge up to 10 gauge thick.
