Looking for the hive's thoughts on MIG welders.
I'm looking for a welder that does at a minimum 3/16" in a single pass on mild steel with the GMAW process. I went to the local welding shop and found that typically when they rate a MIG welder for "maximum in a single pass" they rate it for flux cored wire and thats exactly what I'm trying to avoid.

I should note I do not have 3 phase available to me at the moment. Only single phase 220.

Oh, and before I forget to ask about this altogether. To sucessfully weld 3/16" mild steel in a single pass *about* how many amps is required and what would be a good diameter solid core wire to use? 0.35, 0.45? I know it varies from welder to welder and from electrode to electrode on stick welders, but I'm trying to get a feel for what I need as far as MIG welders go.

I was leaning toward the Millermatic 210. Has a decent duty cycle (60% @ 160A - 24.5VDC)
Don't think I can come up with more than about $1600 for this expenditure.

I'm going to be honest I really don't know a ton about MIG welders, I learned on sticks. But these days I'm looking for a cleaner bead and so are my customers. Some input from you guys would really be great as I do value it.

Thanks guys (and gals)

I am a welder at PSNS... however, I don't warrant the additional cost of MIG training yet. (Trying to get TIG 100S1 in afterhours class coming soon). Anyways, we sit around and bullshit half the day on the weekends. I'll print this and see what they say.

I'm going to double post...

I really need more info on what you are wanting to weld... thickness of metal... diamiter... exact type of metal... also you say you want a 3/16 thick in one pass? What width? Any info would help.

Mild steel (hot or cold rolled), 3/16", bead width doesn't really matter in this application.

I run .035 solid on a Miller 251 at 18-20 volts for short arc but, I do more spray welding at 27.5 - 28.5 volts and I run it mostly on 3/16.



+1

When you get into the spending range you are in you start getting more amps for less money at that point, so buy big. 3/16" should need about 160-170 amps to do on a good day running .035 on gas IMHO....

Up-armored Scirocco, perhaps???

I know what else I was going to ask, how much does it typically cost these days to fill a 60cf tank of 75/25% mix?

I like her holster better



Where is RS Coyote; is he still in the doghouse?

Nope. I'm still around.

Wombat that machine looks awful familiar.

Rob go with what 1GR said you won't go wrong. I had a Miller 210, used it for a few years & sold it for about what I paid for it (the sale price) and now have a 250. I did the same thing with the plasma cutter, I had a Thermal Dynamics 50 and now have a 101.
