​Lincoln MIG Welders Comparisons

​My readers seemed to be interested in comparing the Lincoln 140 Weld Pak to the Lincoln 140 Pro MIG 140 welder, and to the Lincoln 140 MIG Pak and the Lincoln Electric 140 Easy MIG welder. ​

​Readers were also interested in how the Lincoln HD 140 compared to the Lincoln Electric Handy MIG.

​That specification comparison table is later on down the post. Use the table of contents to jump straight there to see that now.

The Lincoln 140 spec comparison to the 140 Pro MIG and to the MIG Pak 140 and to the Lincoln Electric 140 Easy MIG 140 is right here.

​The Lincoln 140s All in a row.

So what's happening here? Why do they look the same? …

​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'll 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 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 them 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 ...

Looking for a beginner MIG you can always take a peek at a MIG comparison here on the site.

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. Or 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.

What about the Lincoln Pro MIG 140 duty cycle? And the Lincoln 140 MIG Pak?

​Yes, as they are the same machine as the Lincoln HD 140 and the same as the Lincoln Electric 140 Easy MIG. All their duty cycles are exactly the same.

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.

So what does that really mean?

For those new to welding this means that when you are using the 140 Weld Pak for a ten minute span, you are able to weld for 2 minutes at its maximum defined rating which in this case is 90 Amp and then will need to leave the welder to cool for 8 minutes.

This also means that running the Lincoln electric 140 HD welder at its maximum capable output of 140 Amp that you will be able to weld for a much shorter period before you'll need to stop and let the welder cool.

What else …

​Lincoln 140 HD Mig Welder Controls

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

Two dials, one for setting your welding output voltage and the other for the wire feed control 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.

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 as the welder needs the fan on.

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 a dial.

Weld Pak 140 front dials and On Off Switch

Weld Pak 140 front dials and On Off Switch

The dial is a tapped dial with output settings from A to D.

What does that mean?

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

That means 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 voltage output dial on this Lincoln 140 Weld Pak runs from A through to D in four welding voltage output settings.

The Lincoln Electric 140 HD welder has a welding output of 30 to a maximum 140 Amp across the four voltage 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 stainless steel or Aluminum)
  • the thickness of metal you are welding together
  • 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 detailed 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.

In this YouTube video moment 2 I have for you, 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 one.

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

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 beginners project with this welder.

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

Better Welding Penetration

It's worth checking the welding wire chart for what Lincoln recommends for size and type of metals. For example they recommend Flux core -  their Innershield brand name wire for welding 1/4 of an inch to 5/16th of an inch mild steel for deeper penetration.

Welding in the Home Garage?

Yes, Convenient to use the Lincoln Weld Pak 140 HD needs 115 volt input and uses a normal house 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, as that will take away the available power to your welder and will affect the quality of your welds and even if you can successfully weld at all.

​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.

What Wires Does the Weld Pak 140 use?

​With an Aluminum drive system that's solid and sturdy to prevent crushing or tangling of your wire feed, the quality of the wire drive system makes it clear that you are not looking at some plastic cheap import.

Lincoln Electric 140 HD Drive System

Lincoln Electric 140 HD Drive System

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

The Lincoln 140 HD uses 0.030 to 0.035 inch flux cored wire or 0.025 to 0.035 inch solid steel wire.

If you want to weld Aluminum you will need to purchase separately the Aluminum spool gun. The Lincoln Weld Pak 140 HD will use 0.030 inch Aluminum wire with the spool gun.

​Would you like to take a look at some welding wire options?

I have some articles on the site that could help you

Enjoy!

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?

If you are not using Flux core wire and want to use the Lincoln Electric Weld Pak 140 HD as a MIG then you'll be swapping to solid wire and also using shielding gas.

The Weld Pak 140 HD can use a standard 75% Argon and 25% Carbon Dioxide mix for mild steel or 100% Argon.

The Lincoln Weld Pak 140 HD is supplied with a dual gauge Harris gas regulator. Which is a good quality regulator. The Weld Pak 140 will also use 100% Carbon Dioxide though you will need to get a regulator designed for Carbon Dioxide to be able to run this gas.

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 depending on whether you are using flux core or solid wire with shielding gas is easy on this welder.

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

Welding Aluminum with Lincoln 140?

Yes, with the Lincoln 140 Aluminum optional spool gun. It is an optional extra and the compatible ​Aluminum spool gun is called the Magnum 100SG.

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

The Magnum 100 SG spool gun will work for them too and the Lincoln 140 MIG Pak.  ​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.

The spool gun can handle 1 lb. spools of 0.030 " or 0.035" Aluminum solid wire. You'll also need the matching sizes of contact tips and a pure 100% Argon gas mix and then you'll be set.

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

Yes, excellent. Good solid brand and an easy to use welder

2. Can you weld Aluminum without a spool gun?

Possible, more chance of getting into trouble, I wouldn’t recommend it. Aluminum is a soft metal and trying to run it up 10 foot of cable to the MIG gun would be very difficult.
