As it's a "Closeout" item I'd say it looks like it's being replaced by the new MM190 w/Autoset.

I've used the smaller MM140, 115V version and liked its performance on sheet metal and thinner materials. The MM180 should have service support for years to come and if I were in the market for a machine within its range of capabilities I'd go for it. Should also still come with the full Miller warranty coverage.

 

That seems like a smokin deal. I don't have any experience with the 180 but if I were in need (or really want) I'd bite.

 

Yup- makin' room on the shelf for the new models coming out.

 

Yea they are making room for the new inverter MIG welders.

 

Are inverter welders that much better? Keep in mind that I'm new, so you'll have to "dumb" down your answer for me to understand.

 

Yep, new models out. They had smokin deals on the 211's too. Those were sold out the first few days of posting.

I would take it , but with a 140 , 211, 180 SD , 280 CST, and my 302 Trailblazer I'm good for now.

Thanks.

Here's another question, totally unrelated. What determines how "hot" of an arc that a welder puts out? Is it the voltage or the amperage? I'm asking because I see on some of the higher end machines you can dial in both the voltage and the amperage, so I'm wondering what effect each has on the quality of the weld?

I am familiar with Ohm's law (watts = voltage x curent) and that watts equals power (heat). So with that being said, why adjust one vs the other if the ultimate goal ends up the same. Or to make it clearer, if your goal is a certain amount of watts, why can't the machine run at a constant voltage and just change the amperage?

 

Inverter machines are basically computer controlled. They rely on electronics to change and ramp up the power. The transformer machines use some electronics,newer models, but rely on large transformers that are copper or aluminum winded.

I actually like the Inverter machines. They are lighter and smarter. Also with these new inverter machines they draw less power and use it more efficiently.

 

It depends on type of welding. CONSTANT VOLTAGE, CV (MIG) or CONSTANT CURRENT, CC.(TIG, stick) Do a search. Plenty of info.

 

I have been wanting a good welder awhile now but just couldn't bare to shell out a grand for one, but seen the 180 for 649 and before I knew it I was typing in my cc lol. Would I like to have 110 and 220? Sure, but for the money I doubt there's anyone who could argue that the 180 is a great buy for that. I like the fact that the transformer version, even though it heavy it's proven and lasts forever if you take care of it. I struggled with Lincoln but this price really made up my mind, folks are still bidding on these used for $750 on eBay! I'm pleased, can't wait to open the box and see that shiny blue paint! Lol

 

Finally got electrical work finished and got to test it out this morning. Wow, I'm really impressed with this machine, it is honestly night and day difference from the smaller 110 welders. I am well pleased, can't believe how smooth it is, I burned through a piece of 1/8 and just messing around I filled the hole, this is where hotstart really shines! No more sputtering! Smooth as silk, it feels like it's spraying the bead out. I'm glad I chose miller, this little machine is amazing compared the Hobart 140 and Lincoln 140 I've used at my buddies, I guess now they'll be coming to my house.. Lol

 

Great to hear. You did very well on that welder.

 

@Hotstart, Glad to hear that my question helped you find the machine you were looking for. Remember me when you're famous and making Miller commercials on tv.

 

I haven't considered a career in acting, something to consider tho.. Lol. I think this 180 was overlooked by a bunch of folks because of the mm211 and the option to run it on 110. It got me to thinking about how good the 180 would weld on thin stuff. I know sometimes it's necessary to weld .0625-.125 materials so I built a cart yesterday and it couldn't of impressed me more. I Rarely need to weld thin metal but it's nice to know that this 180, even though 220 only, it still welds like a 110 model on low setting. I've said it before, and doubt it'll be the last time, but I am like a kid at Christmas everytime I turn up the power and wire feed to weld -.1875-.250 material. This is the smoothest machine I've ever used. I got a great deal on a few rolls of Hobart n71 inner core 035. I wanted a cylinder of 75/25 but now I'm leaning towards just getting a 8" spool of inershield and not worrying about wrestling with the extra weight
