How bout it?

The Set Up: Thermal Arc Gas Driven switch settings CV/DC+....Miller Extreme 12VS suitcase welder wire speed 250 input run voltage 19 wire used Washington Alloy E71T-GS .045 dia Flux core. I have included a couple of photo's. Aside from the snaky shakey how do they look? I was perpendicular and pulling the middle bead I tried to do C's. More heat, less speed, angle Volts?? Thanks in advance for advice.
Reply:Follow up shot. I kept the same settings as the previous posting and tried to push it and it seems alot better. Is the purple blue anything to worry about?
Reply:don't push flux core, instead use a drag.  I am not familiar with your machine, but try something like 16 volts and about 150-170ipm with about 1/2in stickout.  It is good to brace yourself and use both hands on the gun in order to have a steadier bead.
Reply:welderwomn would have some imput here..She does alot of that stuff.....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.

Reply:Its sure been a long time since ive used that set up. i only did enough to self shielding get used to it. Someone once said when theres slag, you drag.    the way i remember it was we set it up so it sort of felt like you were pushing your had back a little bit when you tryed to weld with it but at the same time  you could maintain a 1/2 inch of wire stick out. You see, the electricity comes from that contact tip, and the circuit is completed with the ground properly installed. the more wire sticking out the tip the further the electricity is away. if you get too much spatter turn up the volts or down the wire speed, or to steep of angle. volts are the heat and wire speed is the range for the setting.   Experiment with your angle. Dont move the gun so you can see the puddle, move your head to see the puddle, and experiment a bit. Have you weld with 7018? the puddle is supposed to look like that some what...      Im not sure of the settings so you will have to maybe check the book. with the right combination you will beable to weld nice stringers with that thing and be careful not to forget what you did cause it might take a while to remember it again. hope i helped.Nothing Ever Got Done By Quitting, Never Give Up.

Reply:First weld in first picture.  Towards the top the travel speed looks good.  Turn down the wire speed and maybe the heat up a bit.  Toy with the settings.  Point the wire directly at the material.  90 degree angle.  Then point the wire away from the direction of travel by a couple degrees.  10 degrees or so.The color is normal.  Steel blues up like that.  Hit it with a brush and it turns gray again.The reason your weld looks better when pushing is when pushing you spread the puddle out and as a result get poor penetration and in many cases fusion as well.  When pulling you penetrate deeper but the weld tends to get a more aggressive crown if not done properly.That one that you pushed does have a nice shape to it and it ties in well but I believe you used too fast of a travel speed as seen in the shape of the ripples.  They are v-shaped and should be c-shaped ripples.  Pushing sort of forces you to have to speed up which can leave certain parts of the weld inconsistent.With that size wire I would run between 18 and 22 volts (if I remember correctly, it's been a while since I ran anything that small but I run faster and hotter on everything I do...).  16v seems too low to me although I can't tell how thick that material is.  Looks like 3/16".  On 16/18g material with .030 wire I run 14.7-15.5v.  Wire speed will need to be tinkered with by you.  Listen for the crackling and popping to disappear and the very rapid sizzle of cooking bacon.  Any pops and you need to adjust your settings.  Traveling with too much of a drag angle will give you some bad crackle and popping even if settings are correct.You really should get in the habit of running straight stringer beads instead of weaving (running "C" shapes) with flux-core.  Shouldn't really weave that stuff like you would with solid wire.  Plus, it will train you to keep a steady hand.Overall looks pretty good.  Still think that first one looks promising towards the end of the weld.  Last edited by WelderBoy; 08-04-2007 at 01:17 AM.

Reply:First and foremost I want to thank everyone for their input and suggestions. I am taking a class at a community college in welding, this is my first semester. The next module of study and lab will be Mig. I have gas/solid wire and flux core capablities (all used stuff). I am very much looking forward to the next phase. We don't get much lab time and their is only one instructor for 25 people so I like to practice at home. I would like to get a couple of certs just to take me down the road of experience. One respondant ask if I ran 7018 and the answer is yes so I will try to use some of the learned traits and apply it to wire. I thought I would include a couple of none welding related photos for your viewing pleasure keep the comments coming I won't get back to welding until next Thursday but will check the forum.
Reply:you gonna send some of that bacon this way?  looks yummy

Reply:lol, nice transition... a live critter to bacon ( deer bacon? ) LOL
