An oldy but goody

[TeenyCAR]

I picked up this old dinosaur the other day in trade for my Hobart 187. It is a Hobart Fabricator and is a 300amp machine. I had to rewire it, but that's it. With minimal adjustment it laid down a pretty nice bead. I'm more than impressed with how hard it hits right off the bat. The top dial is for major voltage adjustments and the bottom dial is for fine voltage adjustment. It has a separate wire feeder and the gun is huge and very solid. It takes a massive spool of wire so I don't think I'll have to change out that very often. I don't use MIG much anymore but I think it is a nice find for the other guys that come up to the shop. Now I just need to find a nice size hobby lathe and mill and I'll be set.

Thats a good machine, built very well.

I see a no-no in that weld :), can you guess what i see :flipoff2:

Yep. he shouldn't be practicing. Just makes the rest of us look bad.

Nice score! I love huge old welders; I got a old Miller CP300 for the shop a while ago to replace a 210 and the sheer joy of 3-phase 480 power backing that big a power supply makes welding a breeze.

nope, care to try again :flipoff2:

a little thing called fish eyes, which is a tattletale sign of the tacking method, or the use of making circles in some form or another, which can lead to a few issues such as lack of fusion.

[reddevil1111]

I am learning welding but his pattern was reheating the some of the same spots he had already welded. he should be using a C motion rather than a circle right?
The pattern looks almost the same when done other than the splatter and the fact that reheating it delaminates the weld from the metal but only where he made the second pass on the weld. The weld might hold, but it has weak flaws in it that could cause the entire weld to fail under stress.
Am I right? Like I said, I am new at this. :evil:

[TeenyCAR]

Actually only the ends were done in the tacking method as I wanted to see how responsive the gun and welder are upon first strike. The center portion of the weld was done using continuous and with overlapping c's. Circular patterns leave excessive material and just isn't needed on a large machine like this welding 1/8 inch material. And I'm certainly NOT worried about fusion of metals since on the backside you can see it "blistering" in some test spots.

What is it with the welding nazi's always wanting to piss all over a person then tell them it's raining.

Post up your first bead on a new machine!

[TeenyCAR]

Passionate extremists, yep they are annoying. I guess I still don't seem to understand how someone can look at a weld and determine if it has achieved proper penetration and fusion. I guess if it was a glob, erratically strewn all over the place but come on. I'm beginning to wonder if you weld critics are omnipresent since you'd have to be looking over my should to see what is actually happening in the penetration and fusion process.

[PTSchram]

I'd hate to think what those guys would think of my welds, the vast majority are in rusty metal patching rusty floors-or at least, that's what it seems like :flipoff2:

Nice score, I never seem to find them.

[Jeepermat]

Nice score, everytime I find a huge ass machine like that it is either 3phase or way overpriced

cause i'm work right now (I.E. i'm that asshole inspector everyone loves to hate) and the fact that i'm a certified cwb inspector that looks over more feet of weld in a week then most people look at in a lifetime, that and weld craters are something i don't get along with well :flipoff2:

You'd be amazed at what can be determined from a good picture of a weld and knowing what process/machine/base metal was used.

Teeny good score on the ole machine and nice looking welds. I know if I dont use my mig (millermatic vintage 250) for a little while I loose the touch and it takes a little practice to get it back. Hell you just got that machine, its older and you picked it right up and layed that down... Sweet...

I think its funny about all the critics that come to this site... Lately the trend has been pro welders:shaking: (i think because more so of the TACK TACK TACK thread...) before it was the structural engineers (you need more triangulation guys) and before that it was the suspension engineers (too much - not enough antisquat guys) and my favorite the english majors (they get me everytime!!!:D)

Hell even in my apartment- shop build thread I had the construction exports judging my dirt work from pictures in arkansas from the computer setting in California:shaking: and guys arguing through 2 pages if the walls should be painted first or the trim...

When it comes to inspectors everything is critical but hell its not like you were welding natural gas pipe lines or food grade stainless countertops...

Hell I realize I am in a shity mood today so you never know I may warm up and delete my post...

(off my soap box now)

You paint the walls first then install the prepainted trim:flipoff2:


I wish I could find a deal like this, I would love to trade my MM 175 for a vintage 250 class machine. It seems like all these deals are always in Cali:shaking:

Yeah i hear you on this, theres always things to. Where i work, its not as critical as high pressure natural gas lines, its just the shear volume of weld thats done in a day (8000-18000ft depending on whether 6 machines are welding for 4hrs a day or all 19 are running for 4hrs a day minimum) thats makes even the smallest issues big problems.

[Po' riggity]

Nice welder, Im coming to your house when I need work done! :D

Nice looking welder. Those welds make me cringe too. :flipoff2: but if you're happy with it, then who gives a damn. I like the analogy of how a bare bones buggy looks better to me because it's all function and the right tool for the job, while a superduty on 44's and chrome shocks will appeal to more (other) people visually and will do a lot of the same trails the buggy will but not as well.
I don't see your aversion to just laying down a straight no frills weld that when done properly looks way better than any pattern or tac method--other than that it's harder to do.

[TeenyCAR]

It certainly isn't harder to do.
It looks like a slug wrapped around a tube seam.
If you can't understand why I use this method by looking at my projects then you're probably never gunna get it. I'm not welding up steel buildings or gas pipe for goodness sake. I'm building an art project that does indeed perform as nicely as it looks. Open up your eyes and get a clue. There are things beyond your industrial weld shop.
I should have known this would have turned into a critique the weld thread. The point was that an old welder while looking archaic is still a nice machine and easy to use. So if you see on of these machines in good operating order, don't be afraid to pick it up. Oh and yes they are serviceable.
Continue on with the pissing match. I'm out.

And that they do, hell i picked up a 1980 miller dialarc ac/dc stick welder awhile back and it works like its still brand new.

Industrial weld shop or not, the same "basic" principles of what makes a good weld apply from the industrial side of things down to the hobbist welder, "weld defects" are just that defects, and is what i sarcasticly pointed out, as braxton said if you're happy with it then who gives a damn. If you want to unknot your panties for a sec try to remember that the weld craters are defects and can cause weld failure no matter the weld bead profile or technique used, i see tacs to keep something from moving around break on a regular basis due to that simple fact of an unfilled weld crater that started to crack.

welded at work today and it looks like a drunk chicken shit all over the piece:D nice machine:smokin:

Sure, it does get played out a bit, but its the way things have worked round here for years. People post up their projects and get either praises or hopefully constructive criticism. Be it a cage with no diagonal reinforcement, a link mounted in single shear, bolts instead of studs and nuts on a steering arm, a tack tack tack weld, or even bad grammar (that one annoys me too, always seemed like grasping at straws to feel superior if you ask me). If someone posts up something that looks like shit, then hell yea I'll call a spade a spade and say it looks like shit, I'll also say hell yea when something looks well thought out and well put together. To see quality fab work put together improperly is just a pet peeve of mine, sorta like building a chromo chassis and using grade 2 bolts to hold everything together.

Teeny and I have had it out a couple times about welding, it doesn't mean I dont respect his fab work, and it doesn't mean I wouldnt have a beer with him if we ever got to meet, it just means I dont like his primary welding method. Who cares, he's not going to change his mind, I'm not going to change mine, which is why I've stopped saying anything about welding lately. However, I cant see giving the welding nazi's a hard time for trying to convince someone to do things the right way, seriously, you wouldn't defend grade 2 bolts would ya? Even if the person you were trying to convince swore they had never had a failure, right?

As for the folks who get all riled up every time someone criticizes a weld around here, take a class or two and learn to weld, ouce you get the knack of it, you'll be suprised what jumps out at ya, even from a pic.:flipoff2:



edit: Almost forgot. Hey Teeny, thats a damn nice ole machine, good score.
