I need to pay you a visit Shield Arc!

I'm home pretty much 24/7.

I'm not real good with thin material, coming from a structural back ground. There was one time where 3/8-inch material made me nervous!

I'd like to get my hands on your welder. I've never run one, but have heard great things about them. Not to sure I would like that auto set. I don't like people telling me what to do, much less a welding machine! :laughing:

The Miller Auto Set is really not Auto Set. it is however a brilliant marketing ploy.. It doubled the sales in the unit class that offered it. You still have to " dial it in ".. Which means it's not much different than reading the parameters off of the cover or in the manual and getting close. No matter though, Any welder that welds is a great tool..

Post some weld pics, I too would like to see them and read feedback. Granted I'm learning stick, but would eventually like to try MIG.

Dragon, Nice job. I have the same 211. Love it. I use .030 wire and pulse on off letting it cool to avoid burn thru. Take a scrap and non auto mode and start lowering the voltage letting the piece cool between passes.
I added a small wire gun, second tank (Argon) and have a great time welding aluminum. 211 does a nice job on that too. Best part, if you scratch your paint, it doesn't rust.

Thanks Rob, I should have tried 'pulsing'. Really, there were multiple attempts on many the joints and I only brushed clean in between instead of grinding. I did grind the finish flat where it was an appearance thing (plainly visible). I probably should have ground some between passes when I had a very poor bead but I was concerned about the stock thickness (16gauge) and taking too much metal away. I NEED to practice and I think on thicker material. I think my speed was too fast and my surface prep on re-trys was poor.

I bought the spool gun too and hope to eventually weld aluminum but only want to bite off one learning curve at a time. The Miller rebate 'forced' me. I know one thing for sure, the welder doesn't deserve me.... yet! :ashamed:

You shouldn't have to pulse(pull the trigger on and off) on 16 gauge if you have a tight fit up but 16 gauge would still be tricky for a beginner. Generally with MIG you want to twist your wrist side to side or go in little circles to ensure fusion at the edges. 16 gauge not so much. Thin material with stick, then I'm like Shield Arc.

ullinghair: Give me 1/2" and I'm fine.

Thanks Arc! Actually now that you mention it, I think a big part of my problem was indeed fit up. Some of my joints were not 'tight' due to sloppy square (lesson learned). I will practice that on my scraps leftover! How's that for getting the cart before the horse!

When I built this lumber rack, all the square tube is 1/16-inch wall. I used .023 wire. My Linde Mig machine had lots of trouble feeding that small of wire. I had to keep the gun as straight as possible at all times. If I would have had the Dynasty at the time I would have just Tig welded everything.
A lot of times on thin material, if I can I run everything down hill. But when building things you can't always roll it around to the best position.

Well sir it's just great to see you getting into welding. Knowing you, you will keep at it until you master it. Your off to a great start plus you have a nice unit to weld with with. I've NEVER had a Miller unit let me down and that's why I use them exclusively.

As far as triggering or I call it "throttling" your torch, well I do it on times and always have. If I'm using a heavy wire and I need to weld a thin metal and a short run I'll do it that way every time because for one it works well, looks great, less warpage and if you get good at it you will get that " roll of dimes" look plus in my case it saves me the time of not having to switch over to a smaller wire or set up the tig unit for a tiny job.

Penetration is critical. Don't let your welds get to high. If they are grind them out and go higher on the amperage. Doing so will ensure a stronger weld. I like to go higher than the recommended amperage anyway and move at a faster pace with the mig. Less chance of burn through, faster work and better looking weld. Clean metal and tight fitment is essential to a successful weld.

If I'm welding really thin meterial I'll even down weld to reduce the chance of burn through. Also be aware that welding anything galivinized is extremely dangerous to your health so use Google for the proper procedure or email me if you want.

There's lots of great advise here so your in good hands. I just wanted to add my :2cents: worth. Looking forward to seeing more of your work.
Thanks for posting and stay safe.
