Welding Class, Day 1
Well, technically, day two, but today was the first day we welded.
My first bead was terrible. Actually, that's an insult to all the terrible things in the world. Nothing about it was really right except the amperage, which my teacher set for me. But after a few hours I had nice, straight, regular beads. Somewhere in there I switched helmets because the one I had was pinching hair out of my head. Turns out helmet 1 had a ****ty lens in it and helmet 2 improved my welds a hundred times over. But there was excitement. A tiny bit of hot crap got into the neck of my shirt, I jumped and dropped the electrode right on the table. BOOM! Sparks everywhere. After getting laughed at by the class and hammering the electrode loose from the table with my instructor explaining the best angle to strike it from I went back to work. I can't wait for next friday! The status on my anvil project depends on how well I'm doing in a month from now. -- B.B. --I am not a goat! thegoat4 at airmail dot net http://web2.airmail.net/thegoat4/ |

Bring the anvil to class with you. Odds are you are running 6010 rod so
you can learn technique, It ought to be good enough to fill the lowest areas before you hard face. |

I took a 9 week arc welding class at and was great. I bought a Miller Bobcat 225 and I love it. I have a place in PA that laser cuts metal from CAD drawings for me (BenCo 1-610-273-3364) and they cut metal parts that are copies of old Gravely weldments. I weld them up and paint them and sell them on eBay for a good profit. I have sold hundreds of them. The thing about welding is practice, practice, practice... The more you do it the better you will get. I have fixed our riding mower and my backhoe. Being able to weld at home is great. I want to get a good MIG welder too like a Millermatic 175. Get one of the instant on helmets, they are great. I got a $350 one on eBay for $80 and all it needed was a $1 acrylic LCD cover.

Amen to that. When I use the school welder, I bring my own lens and
protector. Makes for MUCH better welds. larry g wrote: BB Spend the couple of dollars at the welding store to get a new lens and protector plate for the helmet your using in class.

I did have my shirt burn away from a secondary flame while gas welding, and all I got was some burnt hair and a hole in my shirt. Felt very lucky for that warning! |

This time was much better than last time. I buttoned up my collar
and didn't get any hot **** down there or drop the electrode. I didn't manage to get out to pick up a welding cap this week, so I burned by head a couple of times, but nothing serious. So I got clever and decided to weld a handle to the piece of scrap I was practicing on. For just a split second I hesitated and wondered to myself, "I wonder if we're not supposed to do this?" That was quickly trampled over by another thought, "**** that, this is a welding class." The handle was quite convenient since fumbling with pliers with gloves on is such a hassle. I'm making good progress and each day if we master whatever he wants us to do that day before the end of class, we have the option of leaving early. I think I'll be able to cram in some anvil fixing in another two weeks or so. May have to forgo the hard facing, though, as I appear to be flat broke for the foreseeable future. Damn it. Questions I forgot to ask while I was the when stick welding, how do you reliably start the arc without sticking? Currently I poke straight at the plate and pull back to around a quarter inch then move back down and lay the bead. Usually works without a hitch, but sometimes my electrode sticks. Typically, when that happens it'll stick again and again unless I wait a bit before trying again or move to another spot and start there. Is there some reason for it to keep sticking, or is it more like I'm just getting aggravated? -- B.B. --I am not a goat! thegoat4 at airmail dot net http://web2.airmail.net/thegoat4/ |

On a really frustrating day I'll start the arc someplace easy and leave a trail of beads and slag 2" long to reach the place I really want to weld. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com |

Currently I poke straight at the plate and pull back to around a quarter inch then move back down and lay the bead. Back in high school my shop teacher told us to "strike it like a match" At first it will take an inch or so to do it consistently without sticking. After you can do that, work on doing it in a 1/4" or 1/2". You end up with sort of a semicircular motion dipping the electrode down, grazing the work and pulling the arc up to working distance. |

Is | there some reason for it to keep sticking, or is it more like I'm just | getting aggravated? I learned to do this before I even struck an arc. No power, no helmet, and just swinging the tip of the rod in little loops, barely grazing the work. Depending on your work change the shape and plane of the loop. After awhile you close your eyes and just feel it. I had this down well enough that I was able to start an arc without even physical contact. but that was a long time ago. The idea is that you get the feel of starting the arc then when you go to actually do it, it's almost second nature. When actually welding, you can then feel whether you have an arc or not because it actually pushes back. I watched a guy weld a couple pieces together behind his back. Beautiful job. He did it all by feel. That's someone who knows how his weld is going not by looking at a buried puddle in the slag, but by how it all feels. It's definitely _not_ in the book! Sometimes I have to tap the tip if I'm in a tight spot or trying to restart at an exact spot. Practice this a bit, too. The process is just a bit different when doing a new rod vs. one that's been burned away a bit, but doing it by feel is best, especially since auto darkening didn't exist back then. |

Different rod diameters, coatings have different characteristics. Also, your amp setting may be a bit low. try turning it up about 10 amps. I'm guessing you are learning with 1/8 inch 6013 |

Im not a welder, nor do I play one on tv..but there appears to be two ways to start an arc Jabbing, and scratching. I prefer most of the time to simply start a smidge to the right side of where Im starting (assuming a left to right weld line) and drag the rod a bit and the arc starts and them Im at the beginning of the weld and I can start the puddle and go. This takes practice. Also the rod will stick if the amps are too low and/or the rod is crappy. I kid Ive been working with in welding, was a jabber and was always hanging the rod until I showed him the scratch. Now he is doing pretty good.

You'll find that you can close your eyes and focus on how "the feeling" tells you what to do. "Feel the power of The Force, Luke." Don't sweat what the welds look like right now, and if the instructor knows what you're doing he'll actually leave you along because you're then _way_ ahead of the rest of the class, maybe even him. You might find eventually that your blind welds look better than the ones you get to look at. Welding with your eyes closed inside a corner will be something you can do until the electrode runs out. Truly a cool trick. Actually, I must admit that now that I remembered this exercise I ought to go do it myself and get back on it. This is one of those things that's not in any book. I mentioned the more skilled among us collecting this kind of stuff for a good welding book some time ago and this is the exact type of thing I was talking about. |

Today I realized that my eyes are a wee bit on the sensitive side.
And not just because I flashed myself twice. (: A little back story: I had a rather severe eye infection at the beginning of the semester, so I was partially blinded. Anyway, it's one of those things you just have to wait out, and around tuesday or wednesday I got rid of that last bit of cloudyness. Turns out that fuzz was shielding my eyes a bit. The result, I have to use a #11 filter instead of a #10 now. I borrowed one of the teacher's helmets for the day since the class helmets are all #10 and he'll sell it to me next week--$20. Yippie! I also had the gaudy, ugly, stupid welding beanie on, which was quite comfortable when I wasn't thinking how dumb it looked. That'll finish up my "Stuff to buy for welding" list. Except maybe a shirt and pants that don't smell like oil. Today, I pulled ahead of the class, and finished the exercise early, so next week I'll haul up the anvil and see if I can sneak in a little work on it. Of course, I now have to figure out the logistical problem of sticking that flaming hot anvil back in my car at the end of the day. Perhaps I can befriend a classmate with a truck.

Whatsa "welding beanie"?
Different aps require different filters, eg tig is darker than stick. Also I have read cautionary tales about viewing cooling welds (white hot to red to dark), which some say still emits damaging infra red as well as uv. I think I read this in a machine manual somewhere, as well. I love welding, but this eye business has quite curtailed my indulgence. Too bad the welding course I took was run by a 90 year old Alzheimer's patient. I wound up w/ near second-degree burns from tigging w/o gloves. Took months to heal. Go figger. sci.engr.joining.welding is the welding newsgroup, proly get many more interesting and detailed responses, esp. on technique. ---------------------------- Mr. P.V.'d formerly Droll Troll "B.B." u wrote in message news Today I realized that my eyes are a wee bit on the sensitive side. And not just because I flashed myself twice. (: A little back story: I had a rather severe eye infection at the beginning of the semester, so I was partially blinded. Anyway, it's one of those things you just have to wait out, and around tuesday or wednesday I got rid of that last bit of cloudyness. Turns out that fuzz was shielding my eyes a bit. The result, I have to use a #11 filter instead of a #10 now. I borrowed one of the teacher's helmets for the day since the class helmets are all #10 and he'll sell it to me next week--$20. Yippie! I also had the gaudy, ugly, stupid welding beanie on, which was quite comfortable when I wasn't thinking how dumb it looked. That'll finish up my "Stuff to buy for welding" list. Except maybe a shirt and pants that don't smell like oil. Today, I pulled ahead of the class, and finished the exercise early, so next week I'll haul up the anvil and see if I can sneak in a little work on it. Of course, I now have to figure out the logistical problem of sticking that flaming hot anvil back in my car at the end of the day. Perhaps I can befriend a classmate with a truck.

Different aps require different filters, eg tig is darker than stick. Yeah, 10 is the minimum, while 11 or 12 is recommended for comfort in all the standard charts, so I'm not too abnormal.

I noticed that I didn't much like looking at cooling welds, so I keep my helmet down until I can't see a glow anymore. sci.engr.joining.welding is the welding newsgroup, proly get many more interesting and detailed responses, esp. on technique.

Or get a set of oxy/fuel type goggles, with the yellow lens, the kind that look like snorkeling goggles. The more you weld the more you will understand the toll it takes on you. |

Hmm, can't wear any goggles under my helmet--I have safety/prescription glasses on and anything that'll fit over them won't fit under the helmet. The one I borrowed and plan to buy actually has a yellow filter over the #11 lens, so I think that should cover me. (but I'm still open to suggestions) It was certainly a lot more comfortable than other helmets. Though I don't suppose it would do much for those times I flashed myself. -- B.B. --I am not a goat! thegoat4 at airmail dot net http://web2.airmail.net/thegoat4/ |

Then get safety glasses with your script. You must prevent grit from getting into your eyes. The fumes alone will be acidic when mixed with water/tears. Put a piece of yellow film over the safety glasses, or get a yellow plastic flip/clip to go on the safety glasses. By now you've seen the black stuff that gets into your nose, thats also going into your eyes. |

I'm already wearing safety glasses--I wouldn't go anywhere near any of this **** without 'em. I'm just wondering if I necessarily need tint on the glasses themselves, given that my helmet seems to be taking care of all the light now. Honestly, I've never heard of doubling up goggles or tinted glasses with a welding helmet rather than just moving to a darker lens on the helmet. So I don't necessarily see what benefit I'd gain from putting shades over my glasses and it seems like it wold be a needless hassle when positioning and inspecting. -- B.B. --I am not a goat! thegoat4 at airmail dot net http://web2.airmail.net/thegoat4/ |
