View Full Version : Millermatic 110v vs 220v welders

I see Miller has a 135 amp (110v) unit for about $670 on Ebay while the 175 model (220v) goes for about $150 more. I have access to both voltages, is the 220v model that much better for at home garage body work ??

Definately go with the 220V. Its built much heavier, will handle thicker metal and the welding is a more stable amperage/voltage on a 220 machine vs 110. (easier to weld with).

Love my MM175...

I had a 110v Miller "cricket", that I wore out, it was great.

I bought a 220v Lincoln, that I hate....can't seem to control the heat...too hot. It sits in the corner now.

I now have a 110v Miller and I'm in love again.

I also love my 135. The 175, as phil mentioned, will of course weld heavier steel, but for your use, I think the 135 will work fine for you. I would get one with infinite heat setting, rather than just 4. That was one of the most important feature when I shopped for my welder.

i cant tell that much difference between the welds or simplicity of use of the mm135 and my 175 lincoln. they both weld very well on sheet metal but my lincoln does surpass the miller on the thicker metals. if it wasn't for having a metal fab business, i probably wouldn't need the lincoln

The new Hobart HH187 is the absolute dogs bollocks, TSC has em on sale for under $600...

I'm "almost" tempted to get one just to run with .023 so I didn't have to fiddlefaff about with swapping out spools etc on my MM210

I have a question. What are the amperage (draw) ratings for the 110 versus 220 models. In looking at them, the 135/140 amp (110v) models require a 110v/20A plug. The 175/180 amp (220v) models seem to require a 50 amp plug. Does that seem possible? My 5 hp two stage compressor only reuires a 30 amp plug.

It seems that the 140amp model would fit my hobbyist needs, but the 180 amp models aren't that much more expensive.

Just another question. Would a 220v mig welder run okay on a 6000 watt generator? I know it would have enough power, I was just curious about surges that could harm the circuitry in the welder.

Bruce, on your 5 hp 2 stage compressor - look at the info tag on the electric motor and see what its rated running amperage is. A true 5 hp 220v electric motor should be drawing in the 20 - 25 amp running load. You can usually double that on startup. My Quincy compressor needs a 50 amp breaker.

We have five Millermatic 130 and 135's at work, all SUPER machines. We do all bodywork using these tools. If you are welding sheetmetal, body framing and what not it is all you need. If you are planning some frame welding or anything over 1/8" get the 220 for sure. But you just can't lose having the 220 no matter what.

Like my brother says "I never said Damn I wish I would have bought the cheaper tool". :)

Thanks for the help guys....guess I'll have to save up a little more!

I notice that you can get a Clarke 220v - 180 amp output mig or a Hobart 110v - 140 amp output for about the same price. In downloading their manuals, I notice that the Hobart manual is much more professional and informative. It seems as if parts availability is better with the Hobart also. In your opinion, which one would you recommend? Keep in mind that I am a pure hobbyist.

I am leaning towards the 110v due to portability and the fact that I only have 40amps coming into my garage.

As always...Thanks for your help.

If portability is a real issue than go with the 120 volt Hobart .

If it isn't than go with the Clarke 240 Volt unit. The duty cycle is what is important also. I believe both of these machines have a pretty good one.
I would go with the one that was highest.

Mooch :)

Most electrical codes require a 25% safety factor in load vs breaker/wire combination. The MM175 used 19.1 amps at max draw so it only needs a 30 amp breaker. That said - you will need to have the plug changed.

Miller makes agood welder.We still use a Miller Sidekick in our shop,we also have an HTP 200 that we use for heavier stuff,the little sidekick gets alot more use. Once again get a welder that you can run co2 or argon mix if for sheet metal. Bobby.Ironhead59

120 vs 240, 110 vs 220 or whatever is not the issue. How much welder do you need?

The higher voltage welders are such because as the welder's capabilities go up, so do the current demands. Where I use to work, the welders were all
480v becuase they were used at very high setting and run all day. The more current, the higher the amps will be. The higher voltages make amps more manageable.

I say all this because so many times I see a discussion like this and all that is talked about is the voltage. The demands that will be put on the welder is what is important. I presently use a 160 amp Century brand. It has a low duty cycle, but then again I rarely weld that much at one time. Most of my sheetmetal welding is in small bursts any way so as to avoid as much warpage as possible. If I have any serious heavy welding, I use a much larger Lincoln.

I have seen people advised to buy a Miller 175, when a 135 will do. For the money difference I would buy the 175 too, but what if a guy only wanted to mig some patch panels on and did not have the higher voltage in his garage already? It is about what YOU need and what is practical for YOUR situation.

Talk to your local welding supply dealer and they will probably be big help.

I have the Hobart 135 Handler and it works very well with .023 wire, just have to get the feel of the machine. The one thing I do not like is the short chord, I have a 25' length of 12-2 with ground that works great for an extension just a mess of wire. I can run mine on my 6000W gen with no problem and gives a great weld.

I'm actually looking at the Millermatic 140 (http://www.millerwelds.com/products/mig/millermatic_140/) maybe with the Autoset (http://www.millerwelds.com/products/mig/millermatic_140_autoset/). This is the new model replacing the 135

I was looking at the 180 (http://www.millerwelds.com/products/mig/millermatic_180/) but without 220 it's not doable
