Inverter Mig Question

I'm shopping for a new mig. Either a 220 or a dual power unit in the 180-210 class range.

I've never used one of the new inverter welders. They all weigh much less than the older type, but they cost more and are not available in all brands, sizes, etc.

Do they weld better? make a better cleaner arc? Are they worth the extra? Are they as reliable?

Thoughts and experience from those that have used both is appreciated.

Thanks

Also wondering ...
I'm looking for a continuous variable voltage control for tuning my alum welds better.
Is that a feature of an inverter machine (meaning i need to get one to get the other) or are some transformer models have continuous variable voltage?

Thanks

Assuming you buy a quality, name brand machine, you will have no worries. Dual voltage is the way to go, but will cost extra. One absolute must have is the ability to use a shield gas and not just flux wire. If the regulator kit is extra, spend the money and get it ! Others will tell you which other features are important.

3 years ago I bought 170A Kemppi inverter MIG. It's by far the best single phase welder I have used and I have tried many. Much better than older welders 5 times it's size and weight (or more).

Granted this is not a hobby machine, at least it's intended for professional use as well and it was quite expensive.

So generally speaking it seems to be the same story as with stick welders. You replace the good old 200lb welder with something that looks like a lunch-box and weighs 12lb and it is just as good if not better than the old one.

Miller 211 and don't look back
I love it and it will make you think you are a good welder

Get the Miller 211 Inverter machine.

Yes, I was an improved arc with this machine vs. my brother's Miller 252 when running the same wire, gas, and steel parts. The 252 is great, but it is huge and heavy, and is not 120v capable.

The 211 inverter is the most versatile mig I have read about or used and the price was great with the miller rebate. I added a 15' mig gun and the 150 spool gun. It is great for a beginner and, unlike the 120v only units, is good for small professional jobs. I had a Miller 135 and have used my brother's 252, and the 211 inverter has the best of both worlds.

If you have the space, money, and possible need for a bigger machine, the 252 is very nice and you can run the spool gun and mig gun at the same time and instantly switch between steel and aluminum work. It was overkill for most of what I do.

out of forty years of welding. i had never needed to weld anything out of aluminum. I dont think i have anything aluminum in my shop. I alway figure those that brag about buying an aluminim spool gun was so they could be macho, like the black four door diesel truck deal. hey baby, I can weld aluminum with my high dollar gizmo here

I have a Lincoln Power MIG 210 MP and absolutely love it. Very easy to set up and is dual voltage. I no longer have to guess when setting it up for MIG either, just go through the menu and it sets the exact voltage/feed perfectly.

Also what kind of aluminum work will you be doing? A spool gun on a "small" machine isn't very productive or easy to get good penetration in thicker pieces.

Hell maybe we all should just toss our spool guns in the trash, not!!!!

In the last year I have welded an aluminum trailer, snowmobile chassis, truck tool box, landscape trailer racks. Also made and welded several dozen aluminum dock corner ends for the lake.

I recently bought one as well with the tig set up. I've been using the $hit out of it and love it. I have a very experienced body guy in my shop using it as well that's super impressed.

Some weeks I do more aluminum than steel. I'd throw out my coffer maker before getting rid of my spool gun (and if you knew me you'd know that's saying a lot ...lol)

I'm leaning towards the Lincoln 210. The miller is a nice machine, and while i don't really care for the whole walk you through the set up on a video screen approach of the Lincoln, I do want voltage and wire speed read outs. When I find the sweet spot, i want to know what it is. And the continuously variable voltage helps find it.

I often finish a task (say 1/8 alum angle), switch to another job (maybe steel), and later come back and do more work on the alum angle. I hate having to find the sweet spot again and trying to remember ... oh yea, it was voltage 4 and speed about half way between 6 and 7. The numbers dials are a pain in my book. Every machine should show me what it is doing. I want to know 18.4 volts at 330 ipm etc. So the Lincoln wins out on that point.
The simple readouts (like an everlast) would be fine, but just dials with numbered voltage is annoying. Have you ever wondered if voltage 5 on one machine is the same as voltage 5 on another? The simple LED number displays cost about $1 in bulk. Why they don't use them is a mystery to me.

I considered the hobarts. They have good reviews and are a little less, but since Lincoln raised it's price, so did they. Their 210 dual voltage is an 80lb transformer model with no readouts and only saves me about $200 but then the spool gun costs more. I think in time I'll forget what it costs, but I will always notice how much I like using it, so I'm going to bite the bullet and go Lincoln unless I find another of similar value. If Miller had a display I might have gotten theirs.

The everlast models were interesting. They have inverter models with extra features better priced than Hobart, OK reviews (a few quality issues) but they are out of stock and don't expect more for weeks and their spool gun will cost more than the Lincoln if i get the package from Lincoln.

You want to weld Al - get a real welder

Al takes heat and lots of it. You can always weld thinner but with a small machine you can't weld Thicker.

Don't get me wrong - Love Lincoln Welders, have a 175 Square Wave I do Tig with. But when I want to MIG Al. I use a Miller 304.

Mig for Al. is one of those "Go Big or Go home" kinda things

One day I might just get a bigger machine (with pulse) for aluminum.
For now the 210 should handle most of what I do (1/8) just fine. :)

When your buddy comes over with the "Brake Stay" for his new Harley -

"Its just a temporary Fix"

"Just need it until the new one comes in"

"I hardly ever ride the thing"

"Brakes - who uses brakes anyway"

Al depends on what you do. First started tig welding in 1978 and with formula cars welded more aluminum than steel.
Since it is non repetitive welding projects tig was the way to go.
But have a Al shelf set of parts bin holders all clamped up and ready for my Miller 200 with spool gun when I get back from vacation.

The lack of volt and wire speed read outs on the 211 is my main gripe. That machine was built to be capable of more than just hobby work and it is very possible for people used to using bigger machines to use this one at home or for a portable machine, and it would be great to actually know what it is doing.

The 211 will weld 3/8" thick aluminum or steel, and is rated at 230 amps. It is impressive on steel when turned all the way up.

If I need more, I will crank the 330 abp up to kill mode and fry the part with 460 amps of output with a 100% duty cycle at 300 amps. They all have their place.

If you have never worked with or welded aluminum, you are missing out. The spool gun is a fast way to get it done and limit the heat input. I used the spool gun to make a frame for the slats that go in the water table, of the CNC plasma machine that my dad and I built. The water tray is 0.090" aluminum sheet and I welded the corners with the tig welder. If I had used steel, it would have been much heavier and more prone to corrosion.

Get this.......people have actually paid me to fabricate and weld parts from aluminum. It is also great to be able to repair or modify aluminum parts and not have to stick it together with jb weld or epoxy.

well if the brake stays are breaking on new Harley's, I'd tell him to take it back to the dealer ...lol

And if my buddy needs me to weld something heavier than the 210 can handle he can help me buy the bigger machine. I'm not his banker.

I'm not knockin the benefits of a bigger better machine. I'll welcome any one who wants to buy or give me one ha ha

How about titanium ? 317L stainless ? Inconel ? No ? Then you probably mean you've OWNED some welding machines for 40 years ;)

I agree with CGT80. A simple voltage monitor with read out would add maybe $5 to the cost. (Heck I can buy one retail for $15 and wire it up if i was inclined). Why Miller doesn't have them is beyond me. I think every mig should have them. The stupid numbered voltage doesn't tell you anything.

it's insulting to wonder if maybe they think we are to stupid to understand voltage. I guess they are too stupid to know it's why I didn't buy their machine.
