All The Lincoln 140’s In A Row

What’s happening here?

Why do all these Lincoln 140 spec’s look the same?

And why does Lincoln have so many MIGs with the same specs?

Read on…

Lincoln Electric sells this welder through a few distribution partners.

Amazon, Lowes, Sears, Home Depot etc.

The different names mean each partner can sell the same welder under their own brand.

A name that is unique to them.

And a name that makes it sound like it’s a specific welder only they sell.

An example is:

Lincoln Weld Pak 140 HD’s are typically sold by Home Depot. That’s how you get the HD bit.

Lincoln Electric sells direct on its website the MIG Pak 140.

The review you read here is valid for them all.

The Lincoln 140HD Weld Pak or 140 Pro MIG welder or the 140 MIG Pak and the 140 Easy MIG welder.

And I’ll use the names through out this post.

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

Not sure how to go about picking the right MIG welder?

I have an article you might want to read first.

The Lincoln 140 HD Duty Cycle

When you’re in the know. You’ll realize one of the first things you want to discover about a welder is its duty cycle.

The Lincoln 140 HD duty cycle is 20% @ 90 Amp output.

So what?

This duty cycle makes it a decent welder. But not one built for heavy welding tasks.

Curious to know more about the Lincoln 140 Duty cycle? Read more here.

Lincoln 140HD MIG Welder Output Controls

You’ll discover that your Weld Pak 140HD is simple to set up and use.

You’ll find the on/off switch on the front.

Pro Mig 140 dials
Pro Mig 140 dials

Where you’ll also find the two dials you control your welder with.

One dial you use to set your welding output voltage.

You’ll find it’s a tapped dial with output settings from A to D. And that controls your welding output of 30 Amp to your top setting of 140 Amp.

The other dial on the front you use to set the speed your welding wire feeds out at.

Want to find out more about the Lincoln 140 Weld Pak settings? You can take a look at this document on the site.

The thermal trip protection light is there too. And will signal when you go over the Lincoln 140 Weld Pak’s duty cycle.

Are you 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

You’ve inbuilt protection if you go over your Lincoln Electric Weld Pak 140’s duty cycle.


This is to stop you doing terminal damage to your welder because of over heating. The inbuilt protection will stop your Lincoln 140 HD welder from welding. And the light on the front will come on.

Then you’ll need to wait for your welder to cool.

The thermal protection will reset automatically.

But there is a circuit breaker on the back which will pop out. You’ll need to press and reset it manually.

Lincoln MIG 140 Metals And Thickness Welded

Mild Steel

Your Lincoln MIG 140 welder will weld mild steel sizes from 24 gauge through to 3/16th of an inch in a single pass. 

Your Lincoln Easy MIG 140 can even weld up to 5/16th of an inch thick mild steel.

But when you’re welding 1/4 inch to 5/16ths mild steel you’ll need to take multiple welding passes. And you’ll need to use flux core wire to get good penetration.

Lincoln recommends their Innershield flux core wire for welding 1/4 of an inch to 5/16th of an inch mild steel.

Flux core welding wire is well known for better weld penetration on thicker steel. Though flux core wire welding can produce more welding spatter.

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

When you’re looking to weld steel thinner than 24 gauge. Say for example car panels.

You will need to have a skilled light hand. Or risk blowing through the thin steel.

Perhaps not something for a beginner’s project with this welder.


Your Lincoln MIG 140 will weld 22 gauge Aluminum. And up to 10 gauge Aluminum when you use its optional Magnum 100SG Spool gun.

Stainless Steel

There is no indication of the Easy MIG 140 welding stainless steel. Welding stainless steel does take more out of MIG welder.

Powering Your Lincoln 140HD Weld Pak

Welding in Your Home Garage?

You’ll need a normal 3 pin household socket with a good earth. A socket that outputs 120 volts.

You will need a 20 Amp fused circuit at least. or you to use your Lincoln 140 HD welder. To use its total welding output, you’ll need a 30 Amp fused circuit.

No matter which fuse type you use don’t be tempted to power anything else on the same circuit as your 140 MIG welder.

Because that’ll take away power your welder needs to use and will affect the quality of your weld beads.

And you may have trouble even striking an arc.

Lincoln 140 Welder Wire Size And Types

Flux Core Welding Wire: you can use 0.030 to 0.035 inch flux cored wire.

Mild Steel Solid MIG Wire: you can use 0.025 to 0.035 inch solid steel wire.

Aluminum Solid MIG Wire: you can use 0.030 inch Aluminum wire.

You can buy and use reels of two pounds (four inch) welding wire. Or ten pounds (eight inch) in size.

Your Weld Pak 140 comes with an adaptor so that you can fit in 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.

The Wire Feed Drive System On The 140 Weld Pak

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

And best of all, your Lincoln Electric Weld Pak 140HD has an Aluminum drive system.

This 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. Here you’re not looking at some plastic cheap imported welder.

The wire feed speed control is variable. You use the wire feed dial on the front of the unit. You can pick the speed you want between 50 to 500 inches per minute.

What Shielding Gas Can The Lincoln Electric 140 Welder Use?

Using your Lincoln Electric Weld Pak 140 HD as a MIG welder will see you using solid wire. And getting yourself a tank of shielding gas.

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

The Weld Pak 140 will also use 100% Carbon Dioxide if you want to use that for your mild steel projects.

Would you like more information about shielding gases for MIG welding mild steel? Click here.

Your Lincoln 140 MIG welder uses 100% Argon for welding Aluminum. The gas you’ll need to use to weld Aluminum.

Your Lincoln 140 comes with a dual gauge Harris gas regulator.

You’ll find it a good quality regulator for feeding your MIG gas. But it’s for Argon gas mixes only.

Want to use 100% Carbon Dioxide to weld with?

Then you’ll need to buy a regulator made for CO2 gas.

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

Lincoln MIG Pak 140 Changing Welding Polarity

As needed you’ll need to also change polarity when moving from welding flux core. To solid wire and shielding gas.

Changing the polarity from positive to negative is easy on this welder. And it’s the simple swapping of terminals on the inside of the cabinet.

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