030 for sure. Especially in a smaller machine. 035 wire is more useful if you have more power. https://www.millerwelds.com/resources/article-library/miggmaw-101-setting-the-correct-parameters

 

I would say for a smaller MIG machine that .030 would be the best. I ran .030 in my Millermatic 250 for years and when Airgas bought out my welding supply store they quite stocking .030. I had to switch to .035 and I didn't think it ran has nice on .125 and under steel.

 

I have not seen any Dual Shield from any manufacture in a size less than 10 to 11 lbs. and no smaller than .035.

 

Apologies, I am not following your comment. I found Lincoln NR211 in 1 lb. spools in the .030 size wire.

 

Dual shield is a different wire than flux core AND regular solid mig wire.

@Snyperx, you do not want dualshield.

 

.035 is usually for 1/8 to 1/2" thick stuff (obvious go to .045 for over 1/2" stuff)
.
.023 is for 1/8 and thinner common for sheet metal fabricators
.
.030 might be if you always welding 1/8 to 1/4 stuff but i normally just used .035 or .023
.
never mind i just saw you asking about flux cored not solid wire

 

I made the same mistake, I thought he was asking about solid wire

 

Apologies everyone. I edited my original post.

 

The minimum/maximum current ranges on a .030 T-11 are a perfect fit for a 140 amp machine. Don't know why you'd want to roam outside that range. You might gain a little bit of heavier 'fill' with the .035 but you ain't going to get beyond the machines max amps regardless of wire size.

 

For a weekend warrior I would go with .035 flux core . For hard wire I would go with .030 At home it is rare to weld heavier than 1/4 and .030 hard wire will handle that no problem. To me anything less than 3/16 .035 hard wire is too heavy . .035 flux core will do 18 gage up to 1/4" but will be smokey in an enclosed garage.

 

since the OP specifically has a Lincoln 140HD, I would say go with 0.030" E71T-11 (gas-less) flux core wire. If the machine was more capable, I'd suggest 0.035" but that is not the case here.

 

I agree, given the machines max capability .030 hardwire AND flux core would be most versatile. .030 will run great from almost the lowest limit to the upper limit of your machines capabilities in terms of material thickness. If you weld something really thin you may want to switch to gas shielded and go for .023, but that would be at the very very lower limit.

 

I think .030 is a very good choice, whether fluxcore or solid, it seems to me to have a good thickness range, at least for what I do, I have a 180 amp 240 volt welder though.
I have gone to Lincoln NR211 wire for fluxcore though and really prefer it.

 

I thought he was talking about solid wire too. I did buy a 10 pound roll of .035 Blue Demon dual shield wire and it ran nice.

 

Actually his heading doesn't say flux core.

 

No, but he corrected himself by editing his first post, so he learned his lesson.

 

Dont make it complicated.

Lincoln provides two rolls of wire that are just about perfect for that machine.

Use them. Go stick some metal together.


Welding Wire
Sample spool of .025 in. (0.6 mm) diameter SuperArc® L-56® premium MIG wire- Note: This requires shielding gas
Sample spool of .035 in. (0.9 mm) diameter Innershield® NR®-211-MP flux-cored wire


Notes:
If you read on forums about "solid" wire, this is referring to the MIG wire that requires a shielding gas.

Solid wire and Fluxcore wire are different in density even though they are both are listed as .035

Fluxcore is hollow- the flux is inside. .035 solid wire is not the same size/density as .035 Fluxcore wire.


That is why the Lincoln 140 can run .035 Fluxcore but not .035 solid wire.


Make sense?

 

Totally makes sense. Thank you.
