Well, I know NOTHING about welding … but how are you doing with the bikes???

DaveInGA · Jul 10, 2019

Okay, this may be a bit late in the process, but if you were going to upgrade a 070 to an 090, who's cylinder kit (cylinder & piston/rings) would you use and why?

Also, where can I get the rim sprocket setup to fit the larger 6 foot (?) 090 clutch? I'm guessing most any brand will do, but finding the larger diameter one has been hard to do.

Finally, did I mention bikes earlier (I've got a kid's bike that needs new tires for him to ride.) or did somebody else? I musta missed something and of course I'm nosey.

Thanks again,

Dave

Also to my last post, before someone replies something. This is my opinion. If you go to any formal school they will teach STICK first and I can understand why. A monkey can run a MIG, It is the easiest form of welding available to the masses.

However If we can be hypothetical if you take two people, One who has only ran MIG (GMAW) and one who has ran STICK (SMAW) for years. Now take those two people and give them a basic lesson in TIG (GTAW). The one who learned STICK will have the advantage since STICK is much more sensitive to user error watching ARC height and maintaining it mainly.

Now this doesn't mean this person who learned STICK will pick up TIG will be able to run it right off the bat. It's just less cumbersome, the best way I can describe learning TIG is like riding a bicycle expect The bikes on fire, the road is on fire and you have to figure out how to ride it without burning cause Satan is behind you. You will eat though electrodes, have misshapen puddles, bad penetration, and ETC. TIG is also a process you have to have lowish air movement as in a shop/garage or a portable tent in order for good gas coverage. (Same goes for MIG just slightly less headache)

At this point you might be asking why the hell anyone would ever run a TIG. There are upsides, when running right you will have amazing penetration for the heat distributed. Speaking of heat there's less of it put though the work piece (*Arguable*). You will be able to work with stupid thin metals compared to MIG/STICK (With a good machine). You will have ZERO I mean ZERO splatter with TIG. ( When both you and Machine are running right) Also if it's metal it's probably weld able with TIG. Those are just some of the benefits to running TIG off the top of my head.

Now something that MIG does great. PRODUCTION!
With MIG you can literally run forever (joking) because you can keep a continuous weld going where both STICK and TIG can't. The least amount of splatter I've seen has been running STARGAS where commonly it's 25% Co2 and 75 Argon OR 100% Co2 depending on wire that is.

Now there is Shielded MIG wire which is gas-less. But you are talking splatter city. It can also lead to porosity if it is damp. Some say it would be awesome for pipeline welders However I can see a partial argument against it. Once it gets damp it's done. I can't bake it in a metal oven like a STICK and dry it out. Since it's on a plastic roll. Once it's damp it's going to splatter even worse and have a higher chance of porosity.

If you have questions message me.
I would not consider myself the greatest of all time but I can attempt to answer questions if you have them and if I can't answer them I can get them from people I would consider the greatest of all time. This goes for anyone on this site.

Attached are some sexy TIG welds. (Just from a quick search)

Learning to read “the puddle” is what it’s all about.

You get what you pay for. Those cheap Chinese AC tig machines aren’t very good or long lasting.

The cheapest/best I would go with is the Thermal Arc brand. I believe the 186 is the best new one, but I’ve been out of that game for a while. I use a Japanese TA300. I tig everything because of no spatter at all. Tig brazing with SiBr filler is amazingly forgiving and great for mufflers because it flows out and doesn’t burn through much.

I sold my Miller Dynasty 200 when I found the TA

I wasn’t trying to offend anyone if I did everything I wrote is my opinion only. And I’m my opinion if I could only afford a new Chinese tig machine I’d save longer of buy a used name brand in good condition. I have no experience with any of the Chinese saws but have the same opinion on those as the welders especially if your trying to make some money at whatever. They are good at copying stuff right down to the owners manual but not so great with quality control or materials used.

I’ve wanted an ac/dc tig for awhile now and a place one of my family members works upgraded so now I have this new to me thermal arc as of yesterday because the price was right

lehman live edge slab · Jul 10, 2019

Now I just need to go buy some tungstens and a lease on a bottle of argon. Came with a foot pedal and weldcraft air cooled torch

I got my clutch stuff off ebay. Just type in 090 clutch or maybe someone on here can find it. Also make sure the clutch drum is 404 not 1/2.

Most of the 090 clutches are spur drive the sprocket type was outrageously priced last time I saw.

As far a cylinder goes I had a farmertec it had very thin plating and failed. They refunded me. Then I ended up getting a new west which was a much higher quality.

I did a lot of research before I bought those two machines. I watched a video on the vulcan and was surprised to the inside circuits. Most Chinese welders fail because of bad heat dissipation with low quality caps. The vulcan seemed like a pretty good design except it didn't have filters over the intake which is standard for a lot of new welders. It also had a strange daughter board.

For the primeweld 225 I haven't seen a in depth article or video on it yet. However I am thinking of replacing the fans in it with a quieter set. So I'll end up going though it and maybe I'll take photos and put it in the off topic sections.

I also have a Hobart champion 16 AC/DC multiprocess generator welder and the Lincoln suitcase that goes with it. That was passed down to me. It's actually what I learned on as a kid.

I also have a snap on mig. Which is having problems and snap on no longer has a lifetime gaurentee even on their old products. That's why I got the vulcan.

Before you lease a bottle you should also look at purchasing one. Depending on how long you are going to keep it. Sometimes the bottle will end up paying for itself. The amount of money my father would have saved on buying instead of leasing was a small fortune. When I was on school I learned that even if the hydro is out of date airgas will still take it and exchange it without batting an eye.

Awesome machine. I'd get a CK brand 20 series watercooled if I were you. You can make a cooler from a Procon soda pump yourself, or find a used cooler on ebay. Many guys I know just use a big water tank without any heat exchanger. It will seemingly take forever to warm 5-10 gallons of coolant. The CK torches have larger cooling orifices.

No, you didn't, see post #56.

Snap on makes good hand tools but I’d think a welder is best bought somewhere else especially since snap on gives nothing away and you could buy a welder from a company that makes welders for the same money. Have a late 70’s early 80’s millermatic 200 at home also that as much as it’s used will last forever probably. High & low range with 6 heat settings in each and an infinite adjust wire drive. I will look into a liquid cooled torch after I set the machine up on my 20 cu ft cylinder of argon to make sure all is well. Then I’ll rent or buy a big tank because it’s only a little more than double money to fill a 330 cu ft tank vs the 20cu ft. Same hazard fees on both tanks ect.

Sorry we turned this into a welding thread, anybody here that’s done lots of tig on magnesium have any threads going elsewhere on this site? I’ve done some aluminum and a fair amount of stainless/mild steel tig but never any magnesium . I’ve been told hardwire do than aluminum maybe need some old lawn boys to practice on.

It’s hard to get a puddle. Has to be super clean, even more than aluminum.

Tungsten needs a tight arc, like down in the puddle tight

The filler rod is pricey.

Use some crappy old saw cases to practice on. It embeds oils in it super easily though.

So I found a decent price on a 090 rim clutch drum today.
