Yeah, thanks for the info. I pretty much only weld on automotive (off road) related stuff, and I have been feeling lately that .035 is often overkill. I notice I tend to gravitate more towards the tig on anything thinner than 3/16" as the mig is laying down a big bead. I too wouldn't mind having a smaller machine for sheet metal work.
I'm very conscious about the appearance of my welds as our circle is VERY critical of that stuff. I'm not the best at laying down a pretty mig weld, so I'd rather tig most things. On trailers and other stuff that is "mass produced", I'll break out the mig because it's convenient and my welds still look better than what come off an assembly line. I think the hard part of welding is knowing that your welds are essentially your signature, and are the first thing a person looks at. Nobody says "that weld looks strong" , they always say "that weld looks nice" or "that weld looks like bird ****". Also, when your welds are sitting next to a pro's, it really humbles you. The cars we race look like they were welded by NASA's crew; essentially flawless.
It's all time and practice, I'm just grateful we have superb internet resources that didn't exist when I started tig welding only 10yrs ago. My formal tig welding education was 3min of instruction on aluminum.....I've never welded aluminum since. I have ground a lot of tungsten since then while I've tried to figure it all out!
Very similar here. I have found myself using TIG on thinner items that I would probably have MIG welded had I had a smaller machine and wire setup. TIG definitely has its place and I love TIG welding but for some things it is just a bit too time consuming and a smaller wire/MIG machine will definitely fill that gap better.
If you are doing mostly off-road and automotive welding I highly recommend giving some .030" wire a shot. I think you will be pleased.
Funny you mentioned how tough your crowd is on welds. Back in the 90's when I made the move from street rods over to sand rails and sand ATV's I got quite a bit of **** from friends and fellow car club members who thought I was abandoning my roots. I said it couldn't have been further from the truth, I was merely expanding my world and needing a bit more challenge. They thought I was nuts until I told them that in a street rod there is so much to cover up poor workmanship, crappy welds, piss poor welds or down right ****** welds between body filler, carpet, etc. that I needed a bigger challenge because in a sand rail and ATV with EVERYTHING exposed and hanging out there for the whole world to see there really wasn't any way of hiding poor workmanship.

I said it in a somewhat joking manner but it really pissed a few people off and many haven't spoken to me since.
Fast forward to a few years ago when my wife and I got heavily involved in Jeeping and went to a local Jeep event, a little show 'n shine. My Jeep was receiving quite a lot of attention because people wanted to know about my suspension and what brand my bumpers were but didn't believe me when I said I had fabricated them myself. There was a member of the Jeep group present that also works for a well known shop in the area that specializes in Jeeps, he was showing off his newly built Jeep. I walked over and checked it out and introduced myself and he really didn't give me the time of day when I was asking him questions about his build. I was told by several that his nickname is "Weldor ****" so I assumed that he must have been a hell of a weldor and fabricator. He had some neat ideas on his Jeep and the parts used were high end but the execution could have been a little better and the welds should have been much better from a guy with "Weldor" in his name but I didn't tell him that as I was trying to be very complimentary to those things I liked.
One of his buddies brought him over to our Jeep and was showing him a few items then they came back over to his Jeep where I was still looking around. He was trying to inquire as to what shop I worked for and I just told him I had a small shop at home and just tinkered in it. I was going to get his goat and tell him I just bought a welder a few months back and was trying out my welding skills

but before I could his buddy nudged him and said "geez ****, with a name like Weldor **** your welds should look better than a nobody in a garage at home."
I know his buddy was just trying to get a rise out of him and it worked. He was pissed and walked away in a tizzy while his buddy laughed his *** off.
To my point, I completely agree that welds can be critiqued and critiqued hard in a crowd as some are down right brutal. We too have tough crowds and I want to have my welds stand out as my signature but in a good way, not like the other.
All that being said, my welds are never as good as I want them to be but I guess I'll keep trying. Maybe one day I will be able to call myself a weldor and/or fabricator but until then I will just keep my amateur status.
