    Good call enlpck; Starting and stopping on center will make things much harder on you. You're right, relax and take your time. When you're making the passes from about the 3:00 to the 9:00 positions sometimes the slag dropout can fool your eyes and it's hard to focus on the puddle. If this happens go back to technique and trust your eyes second. Try this on a horizontal piece like flat plate. Put your hood on and start and arc and get it established, then close your eyes and run a straight bead (with a weave pattern , just like the cap.) When you are getting consistent acceptable results, you've got technique down pat.

      sorry for the delayed post on the picture, i ended up having to go to hosp last night for seever dehydration and a nasty stomach bug.. fun time let me tell you! here are the pics of the last coupon i ran yesterday. like i said i slowed myself down and i think it came out quite a bit better. these pics have some undercut at the top but i was able to run another stringer after and it was take care of. I like to think i was having a Yogi Berra type day on monday, you know where half of welding is 80% mental.

          you are getting close. i got my 21 about 4 yrs. ago. one of the happiest days of my life passing that bad boy. i think you need to move faster on root, close down gap. i used one hot pass, two fill, and three caps. i don't remember changing heat once set up. i was taught that by fourth tack heat should be dialed in. don't even think of 1/8" for cap (as suggested). your second set of pics looks much better. on test day, don't drink too much coffee. take your time. relax. also remember that almost everyone has to make repairs (grind outs), except on caps of course. lastly, remember to take suggestions on fourms with a grain of salt. some are good, some not so much. no offence to tryagn5, but you were way off on this one. good luck, and keep us informed. i'm 597 by the way. i'm working on ms tig, ss tig, and, ss stick now.

            puma thanks for the advice! are you working on 22 and 41 now? i think thats where i want to go next. least the 22 which is the same test as what im on now, but with a tig root. if i can get that then i will jump to the 1. hows the work situation out your way? 597 is in chicago right? unfortunatly since you've taken the 21 the UA has brought some sticter regulations to the test. there is a 3 hour time limit now, and if the atr's or cwi's catch you making a repair you are automatically looked out, no second coupon that day, and i think it's a 60 day wait for a retest now.

            Davinci thanks! they look much better, as am I thanks for asking! It has been a LONG 2 days!

              didn't know about changes. we are pretty slow here. last i heard around 2000 on bench. supposed to break in spring, lotta school work. i'm going to the school next week to get some pointers. it's a little pita to get there, about an hour drive each way. it's a great facility though, and the instructors are a lot more helpful than before. i've been practicing in my garage. made up a 6g jig, and i've got a bunch of sch. 40 cut offs for coupons.

                Yeah I just got out of mytime in september and they instituted the changes at the start of my 5th year. as far as i know they are UA wide, but it could just be a local thing. Our school just opened 4 days a week for like 7 hours a day for the guys like myself on the bench to get some solid hood time in. Hopefully we can get certs. least our certified guys aren't sitting too long. I know a few guys are talking bout heading out your way to try and get hooked up out to that canada job. I wish i had gear at my house to practice with, but alas no such luck, lucky for you though. I would love to get a nice used machine though.

                  Over Penetrating!

                  Looks like you've got way too much penetration on your root. It makes it look like burn thru and would be a failure in my circles. Close your root gap down to 1/16 - 3/32. Are you running the 6010 uphill? If that's the requirement for your cert, so be it. But I'd run it downhill! For consistenct on your 7018 definitely weave, passing smoothly across the center of your weave and pausing at the edges (I usually count in my head, 1,2,3 or 1,2,3,4 depending on how much fill is needed) Doing this, and pausing consistently for a given count will eliminate any undercutting and give a nice weld profile. Also for 3/32 7018 it sounds like you are running too hot. What you are looking for is the flux to peel back on it's own when the pass starts to cool. When this "shell" peels back and knocks off with a tap of the brush rather than heavy power brushing the heat is right on. On my TB 302 this sweet spot is at 73 amps for 3/32" ESAB 7018. Yours may be different, but try some different heat settings to find that optimum spot.

                    Uphill is the reqiurement for the root pass. I could prolly try to cut the gap and run it downhill, but i think now it would get me looked out. some of the atrs/cwis are really picky now. we do use lincoln fleetweld 5p+ on the 6010. the root is tricky because i find if i speed it up, and dont do a little "push in"when i come back into the keyhole i have a b!tch of a time breaking both walls enough. when i run the 70 well, like the second set of pics i do get a nice peel back with the slag. just a light tap with the edge of a file and it pops of. In the past I've used the Lincoln Exalibur 7018 rod in the field and i like the way that runs a lot better then the low end lincoln rod jetweld lh70 that the school offers and has us use.

                      Excaliber is good rod , I use it for my 7018 at the house. Try some Esab Atom Arc 7018 if you get a chance; It's pretty good also.
