How thick of material can you weld at 100-120 amps?

I think you are right about getting a unit with AC. Better to have it and not need it, than need it and not have it.

dunno at 100, like i said mine is a 200 and I welded 1/2'' material no problem (with enough chamfer of course), you could weld thicker but it's all based on how quick and what's the acceptable warping if you heat up the pieces too much.  the other thing that i noticed when you weld thick pieces is the torch gets really hot, so if you do that on a constant basis you should look at a watercooled torch but i don't think that's something you need unless you plan to do it a lot (not worth the expense otherwise, just have to take a break and let it cool). one thing i noticed when they list the material thickness to me it looks like it's based on enough penetration on 1 pass to create a weld strong enough to compare with the strength of the material you are welding (like for example they say 1/4'' thick for 200Amp tig welder but that's really a walk in the park for the one i have, so that's where i got it from). Aluminum thickness rating is also lower than the steel (or requires more amps).

100 amp is probably good for 1/8'' or maybe 1/4'' with multiple passes, it's really how much penetration you get, you can still surface weld any thickness but the question is if it will be as strong as the the pieces you weld. if strength is not a concern you can weld them together but at a certain thickness you will also develop cracks in the weld if there's not enough penetration from what i could figure out with my own experiments, but since i am far from being an expert and just a backyard/home garage junkie i could be wrong on any of the statements above so anyone who's a welder by profession or more experience and knowledge please feel free to correct any mess in my post.

You also have to consider voltage, some welders run at 18, 24, or 48 volts and up.

100 amps at 18 V is way less penetration than 100 at 48...

so what settings and wire size would you use on a mig welder to get 100Amps at 18 volts and then 100amps at 48volts to compare the penetration between the 2 of them?

Sorry for the delay, I have been busy welding stuff!
Here is the link. They are not cheap! But they are a bit cheaper than the Lincoln and Miller products that have the same features.

I took advantage of their black Friday deal. It ends on Dec 2. They only do a sale once a year. This is a small company, maybe 10 people working there. If you want a HTP machine you need to buy it from them. They don't have a distributor system any more.

very cool machine, the adjustable freq for AC welding is great.

Welder dilemma.  Would you rather have a 110v that you could use anywhere or have a 220v where you may end up at a place without 220v?

most of them that support 240v would work with either 120 or 240 unless you're in Europe, I would go with a 240 to get the extra amps and look for one that supports both voltages. For example Lincoln has a version of powermig 180 that is dual voltage, with 120v works up to 140A DC, with 240v is 180A. The 120v version is only 140A, you get the idea.

PS: i'm not saying you should buy a Lincoln, good choice and quality if you want to spend the money though, if you go on a budget there are Chinese versions less costly (the chinese tig I have is dual voltage)

I'm looking at the Millermatic 141 and 190.  You have to go up to the 210 to get dual voltage unit (though that's not out of the question).  Currently I have access to 220 but that might not always be the case which is why I'm wondering if I should just get the 110 which will work everywhere.  I don't think I'll have any big welding jobs which is the other thing to consider.  Most skid plates/brackets are 3/16".  I don't think I'll be making bumpers.

I think I'm just going to go with the 190 and 110v be damned.

190 is nice, the other one though is only $200 more - but the 190 is lighter and smaller. I believe any household has 240 nowadays, all dryers and stoves run on that (and the water heaters if electric), only challenge is to have it wired but even with the ones that have 120v you still can't use a regular plug/receptacle (you need at least 20 amps if not more depending on the model).
