I used to spry the area around my weld with anti spatter. It worked very well made it so the spatter just wiped right off. Then the can dried up :( haven't gotten anymore.

As others have said: turn up the amperage, hold a tight arc, and  slow down.  If you burn through, speed up a little.  You cannot weld it unless you melt it.  I am with Crusarius, find what is comfortable and produces the desired results and go with it regarding circles, lines, weaves or the way you hold the whip/gun.  You will get better with analysis and practice.

When you start to get picky, you can buy anti-spatter spray at the welding shop.  it will help prevent need to grind that away. have fun and be safe
There is also a nozzle gel that you dip your tip and cup in after warming up that prevents the spatter from sticking to your tip and does not affect the weld. Don't remember brand name but I get the one that comes in a tin and has a magnetic strip on the bottom.

ok, so this weekend I reminded myself it was T-shirt weather in the shop. I had to do a quick repair on a mower deck then did about a dozen tack welds. 

The mower deck repair was about 2" worth of weld. The 12 tacks was not a big deal. Or so I thought. Flash burned my one arm like I have a hundred times. I always forget the short welding is just as bad as the long welding.

So another lesson to be learned. No matter how little welding you plan on doing, at least put 1 sleeve on to cover the arm opposite the gun.

I keep trying to remember this, but I'm pretty sure I'm going to eventually learn the hard way...   :D

I was hurrying to clean up at the end of class tonite and had a dustpan stacked high with hot 1/4" t coupons and was headed for the recycle box. One fell off and with my hands full I kept going. I turned to look back and one of the guys was just bending down to pick it up barehanded when I yelled "Its HOT!" Luckily he didn't grab it, that stuff stays hot for quite awhile. I usually leave it on the workbench for as long as possible but the last round we have to carry out pretty warm.

I think he'll try for testing us next class, I've got to get more consistent fast! These were a few from tonite.  These were the straight forward and back whips, pretty tight with the gun at about a 30-45° forward angle. One thing that is helpful for me is to lock my elbows and feed my body side to side with my legs to keep the nozzle angle uniform. I tried to get fancy and popped the trigger to try to fill the divot at the end of my weld here, didn't work out so good ::). You can see I lurched about an inch back from the end, more to work on.





I had turned up to pretty much spray welding and turned the wire speed down in an attempt to get deeper penetration. It's also much less spatter. The instructor heard my welder and came over "you'll never penetrate like that, you have more than enough heat but you need to shove the wire down into the hot base metal, look at the end, good heat signature but no penetration". I was going to cut these up at work tomorrow if I have time and see what the penetration looks like in the middle of the coupon.

that is why I teach with stick first. learn proper technique and penetration then make it pretty. as you found you can lay down a very pretty bead with mig but how deep does it go.

getting there!  pretty is not always as tough.  just like in life.  Do they test with a sledge hammer, x-ray, or cross section?

I've made plenty of ugly welds  ;D. These were pretty typical of what I was getting at both settings n my last round, I just grabbed a couple as he was killing the lights. First in and last out, I'm taking all they'll give me.
On the 14 gauge they looked them over visually then smushed and folded them in a press and looked for puckers or tears. We were over a backing plate for the butts there which isn't typically what I have in the field when I cut the top off the bush hog :D. I'll quiz him on how they are doing this set. We'll submit a butt and T and then if we make it he'll teach us whatever we want for the rest of the class. I'd like vertical and overhead coaching. I've had an AC stick buzzbox for I guess about 20 or 30 years and have done farm and minor structural stuff with it and have played with homeowner MIG's but when this class came around it was too good to pass up. We are getting to play with an unlimited supply of steel coupons on really nice equipment under a really sharp instructor. His comment last night was priceless to me, I've been of the "turn it up" school and he explained if you don't shove something in there it doesn't help to simply crank it up. I had been cranking it up and slowing the feed down in hopes of slowing down and penetrating deeper, that was kind of upside down.

Know what the difference is between a farmer and a welder? A welder doesn't think he can farm. ;D Seriously, I am enjoying this thread, I know just enough about welding to leave it to the pros. I would never trust myself to do structural although I can lay a bead (sort of). I did a night class many years ago, wore polyester pants to the first session. YIKES! Never did that again.

then the next question is "does your state have a 15 dollar per hour min. wage?"   :D :D :D :D :D :D
or is your welding worth that!  (intended as fun!) 8)

over exposure to ultraviolet rays will lead to skin cancer. I have had all three types of cancer, not from welding, Aqueous, Basil, and carcinoma. Though I was a maintenance repair welder for 10 years I always used ppe. My dermatologist says protection from the sun is just as important as the effect of the rays can be acculmative.
To avoid the divot at the end of your bead, back up slightly and let the puddle fill in, lengthen your arc as you time it to stop as you let go of the trigger.

Most of the time I end up welding with short sleeves and and open collar and I haven't gotten any welding burn.  Not sure why that is the case.  Dumb luck or something.  I don't usually button up unless it's dirty or overhead.  Sounds like I should cover up a little better.  

Good discussion.

You can buy the fire retardant jackets ,usually green in color relatively inexpensively .I've got a full set of leathers,jacket,bib overalls and spats but it's been decades since I've used them . I gave up that burning myself also decades ago .I've got weld burns all over my body from being stupid in my youth .Get a hot one through the top of your trousers some time .That will really made you dance . :D

I don't typically take vanity shots of my welds. This is kind of a rare occasion. The only reason I took this picture is because it needed to be ground smooth for the slide pieces. It was necessary to add an extension to make my sawmill dual width.
